Modeling

I dont exactly remember on which mailing-list I saw this book mentioned but I will never regret my curiosity on that day.
I had been practising object modeling for some time before I read that book and was, at times, wondering :
-what could be the right objects in that situation ?
-where should I put this behavior ?
-do I need "services/processes" objects to operate on my "domain" objects ?

This book gave me really precious answers :
-use the patterns to identify objects
-Let the objects do the work
-Let the object that has the knowledge do the work that requires this knowledge.

I have been practising on new projects since and found the lessons invaluable.

That's why I am not surprised at all about other reviews and I have been recommending the book around me ever since.

The fundamental complexity of business systems is business, not transactions, persistence, gui or any other technical aspect. We have many years of experience with technical matters but we often strive to preserve/improve business value in the systems we build.

This is one of those books that comes along every now and then- that only the fortunate few find and buy and think, what a truly insightful peice of work. This book is one of those times. ANd consider yourself fortunate that you have found it. And to make it even cooler: it is actually good to read!

It is both a philosphical and technical blueprint for the modeling process: forget use cases and such. This is about modeling the domain using twelve pattern players that, alone and in combination, describe virtually all domains. Twelve simple pieces that can be snapped together to make extremely complex models that are robust, resilient and extensible. Amazing stuff.

At 400 pages this is the perfect size book: there is no bloat...just a fortright exposition that well explained and diagramed. This isn't a book burdened with UML (I have a beginners guide to UML that is about the same thickness...UML has lost its way: it's become ridiculously bloated and cubersome and oh so self-important). This book helps your pare away the edifice of UML that adds major complexity to the modelign process and get down to the point of the exercise: modeling. Simple.

This book will give you a set of tools for analayzing domains efficiently: because you will permeate what it teaches you through all your domain analyses, which then make the process easier, quicker, and more effective and the net result will be better and stronger. Then you can layer as much UML on it as you like (UML is like butter, full of cholestorol that clogs the arteries). I guess you could call the tools it teaches you- Rapid Modeling.

This is a good book. Try it and find out. Definintely 5 stars.

There a simple beauty to good architecture. The authors boil down object modelling to 12 patterns that represent the simplest building blocks. With these you can model any system and have that model be comprehensive and flexible for any complex system.

A must read!

PMWIN is a robust simulation system capable of modeling groundwater flow and solute transport. It is easy to use and import figures of differing formats. The GUI (graphical user interface) is user friendly. The text presents all the information, graphics and illustrations of the GUI making it easy to understand and use. I highly recommend this program.

I was using earlier version of pmwin and 3-d visualisation was missing. Therefore I always in preferred to work with Visual Modflow with 3-D explorer and GMS. Now using version 5 of PMWIN with 3-D explorer, I was thrilled. Really it is wounderful and quite simple. I do not find it is less than other counter part Commercial Software. Its 3-D explorer is better than Visual Modflow 3-d explorer.

To learn the groundwater modeling techniques, the students or the professionals need the suitable software and the textbook which explaines clearly the theory and the used software.The book must explaine the procedures step by step and from start to to the end.But nowadays, if you have not enough money to purchase the commercial modflow based software, it is a pity that you have to learn MODFLOW codes.It was the undesriable things.Hydrogeological modeling means interpretation.But there is no possibility to see visual something among the codes.I created the input and as a result output errors during the simulations with codes at the beginning.There is a good words in computer technology; Gap In Gap Out.It summurizes the best what i meant.Definitely all hydrogeologists have to know all background informations on groundwater modeling techniques and the structure of used softwares. But i think, groundwater modeling is more than a science, it is a art which must have a visual effect.So that I have looked for the best groundwater modeling book and the software since 1991.At the end, i have found, what i have ever looked for. This is this book which combines the latest modeling techniques and the latest modeling software.You can learn the latest modeling techniques written by the leading teaching experts and creators of PMWIN.This 344 pages textbook walks the practising engineers or students through the modeling process from start to finish.You don't need any other additional tool.This book has also the best groundwater modeling and contaminant transport modeling software. Especially it is the best learning asistance with example problems for the students and practising professionals.

With PMWIN ,groundwater modeling has never been so easy.It is more than a pre and post processor of MODFLOW family (88,96 or 2000);it is a great modeling environment in which you can find what you needed. You can also realize your all modeling and contaminant transport dreams with using all MOC3D, MT3D, PHT3D or RT3D family ( it was a dream for me ).

PMWIN is an advanced environment which has a digitizer, field interpolater, field generator and environment for the background images or dxf files.You can import vector or raster based images...create your own georeferenced background maps.You can interpolate your datas by using FIELDinterpolater and export your kriging results just in a minute with field generator.You can find 4 different interpolation methos.The most complex 3D preprocessing, such as surface or layer property routines take max.30 minutes.You can enter your values to cells, either in cell by cell method or in zonal method or using interchange options from the field interpolater program.

The PMWIN has a preference options the simulation can be performed either with MODFLOW 88,96 or 2000.The all datas will be controlled by the PMWIN, if needed you will be directed for the deficit inputs.After the modflow simulation has finished, the RESULTextractor gets your results in a matrix dialog. If you prefer to open your datas in an other application such as SURFER, it is also possible, you can export your matrix result. PMWIN creates two output files; one of them USGS's *.nam file, the other is the PMWIN's *.pm5 file.For example if you have only GE, you can also visualize your modflow code simulation results in GE environment because GE reads the modflows *.nam files.

If you have GE (it is an optional, low cost 3D visualization tool.It is the cheapest, the best and the easiest tool in the industry).I have tried the all other visulalzation tools, GE is the best, GE is the simple.If you wonder about the prices, it app.250 USD.The most complex and troublous datas will be shown so clearly in 2 minutes.PMWIN and GE or some other add on modules work seamlessly and perfect.The author and the programmer Prof.Wen-Hsing CHAING had thought everything.I have examined PMWIN with the most complex problems,the program has never stooped or the operating system has never collapsed.The PMWIN 5.1.7 permits 250.000 cells but with MF2K add on modules it can be reached up 640.000 cells. Again no problem, no colapse in system.If your operating system is stable, it works so unique.

If you are an unexperienced modeler or beginner,it is not problem.After one or two day with this book; definitely you will become more familiar.It is so simple that the visualization processes take just 2 minutes...you can create your own animations and import your animation scenes in many digital formats such as *.BMP, *.GIF and modify there and present.

With some additional add on modules which have been created again by the Authors of the book, you can merge with other modeling tools such as RT3D or PHT3D.I have contacted to Prof.wen-Hsing CHAING and learned that there will be a lot of add on modules...one of them is the surface water/groundwater interaction modules.I have also learned that GE will be used for the presentation of the surface waters and the meteorological datas.It means, PMWIN will be the best software in this industry.Many of the commercial modflow processors are still using Modflow 96. The MODFLOW 2000, PEST-ASP and the late version of the UCODE had been added in April 2001 to PMWIN.And it works without any problem since April 2001. I have contacted and got more additional information about the PMWIN and the book. I am gratefull to Prof.Kinzelbach and Prof.Wen-Hsiang CHAING who has written 3D GROUNDWATER MODELING WITH PMWIN and created,developed the PMWIN, GE and MODFLOW 2000 add on modules.I have found the best software and the best TEXTBOOK.This book is really excellent and can be advised both to the students,practical engineers and advanced groundwater modelers, as a compherensive guide to modeling and complete the exercises to refresh their knowledges.And also... Especially for the professors , this book will be an excellent primary text for a university course, or as asupplement to an existing curriculum.

Few books devoted to science fiction modelmaking have punctuated the monotonous and predictable landscape of model building related books, and this one is a stand-out! "The Ultimate Modeling Guide..." covers a broad range of science fiction hardware and model making techniques. Excellent photography supports detailed and authoritative text. I've found it to be instructional and inspirational. This book is for anyone interested in modelmaking. And for the sci-fi specific modelmaker, you library is sorely incomplete until you get this book. I highly recommend it!

Reference books and how-to books for modelers are a small niche in the market, and they've been almost entirely oriented toward the military modeler. Now at last is an in-depth how-to book for the science fiction kit builder. We're not out in the cold any more! Steve Iverson has gathered a gaggle of the best sci fi modelers from around the CultTVMan internet community, and they've given us step-by-step articles on building and improving such kits as Polar Lights' Robbie the Robot and C-57D spaceship, Lunar Models' Proteus and Discovey, and many other mainstream and garage industry models. The book is capped off with a fascinating history of the filming model of the Starship Enterprise from Star Trek: The Motion Picture through its retirement, with some wonderful reference photos of the ship - worth the price of admission alone!

I picked up Cult's book at WonderFest with egar anticipation. What was contained in the book did not dissapoint. It was filled with great kits I never knew existed (& now want) as well as great ideas & tips on building them. I can't say enough about this book & how it will help me build a better kit.

I committed to doing a MySQL project because it was less expensive overall for my client than using software I'm more familiar with (I'm not naming names but let's just call them SQL Server and .Net). I'm very experienced creating databases but brand new to MySQL and PHP. I don't know how I would have survived without Kofler's book. He not only explains everything step-by-step but in a very relevant, clear way. I had several other books in my arsenal and found I dropped all of them when I needed to look something up and just used Kofler all the way. Everything I needed to do, he had an example for in his demo files!

I know from experience how frustrating it can be not to have the right resources available. Although there are some great user's groups and so on, Kofler's book saved me a ton of time because I found pretty much everything in his book. Using his book and the free, on-line PDF MySQL manual is all you'll need to do a complex business application for the web.

Thanks Kofler. You're my hero!

Very good book. The content is very precise and has content which will be useful to newbie as a well as to a seasoned MySQL user. I recomment it to all.

This book covers both UNIX/LINUX and Windows for almost every topic - I really like that especially since we run a mixed environment and I'm wanting to learn more LINUX.

I'm a Windows user who needed to setup MySQL that was required by a free message board [;ocal website]). This book made the MySQL portion of the install extremely easy and covered all of the topics I needed to know to setup MySQL in a Windows environment. He covered all the "gotchas" with both Windows and UNIX/LINUX platforms - nice! It also covers setting up and interfacign with PHP, Apache and other system "components" - which really helped me to deploy my message board project.

I enjoyed his writing style so much, I found myself reading the book front to back, versus looking up specific topics - that doesn't happen very often with these types of technical books.

The information is up to date, even though it's over a year old. I checked out the top 3 MySQL books out there and this one was my favorite for getting started clear through advanced usage - there is not a lot of "fluff" - just a clear writing style hitting all the topics.

The book by Amit Konar is a new addition to the disciplines of Artificial Intelligence and Soft Computing. I am greatly charmed with the presentation style of the author. The chapters on Imprecision and Uncertainty Management (ch.9), Fuzzy Petrinet (ch.10), Spatial and temporal Reasoning (ch.11), neural nets. (ch.14) and genetic algorithm (ch.15) impressed me much both for their simplicity and research-orientation. The book started with a humble beginning on psychological model of perception in chapter 2, and introduced many new concepts to formalize the theory of perception. The last two chapters in the book deal with applications of cognitive science in a criminology application and navigational planning of mobile robots respectively. The CD included with the book contains the programs used to demonstrate the concepts of the last two chapters. The programs can easily be run even by a novice user with the guidelines presented in Appendix-A.I wish you will enjoy reading this valuable book, the price paid for which is justified enough.

This is an excellent book to understand AI. Thanks to the author for his best effort. The book may be used as a text. Examples presented in the book are thought provoking. Both beginners and experts would find it useful.

This book covers a wide spectrum of tools, techniques, theory and simulation of AI and Soft Computing. The book introduces an interesting as well as impressive area i.e. cognitive modeling of human brain- definitely a new paradigm in Artificial Intelligence. Soft computing tools has been explained in a lucid manner for the under graduate and graduate students. Interesting programs on Soft Computing has been provided in the book for simulation. Particularly, the program on Genetic Algorithm for robot path planning is quite interesting. Structural organization given in the preface, helps the novice readers, as well as the teachers in covering the course contents efficiently. Another vital feature of this book is that it has been written in such a fashion that the reader can easily know the name contributors of the original research work. As a teacher of AI for the undergraduates and graduate students, I always look at the course contents of the book, coverage of each chapter and as well as the exercise there in. This book is arranged so nicely that, it becomes very easy on the part of the teacher for designing the course in a modular fashion. Secondly the exercise given in the book is of much use to the students, which I have already experienced in my tutorial class. The book shows many open problems in each chapter, which are yet to be solved. This is quite helpful to the researcher as well as to research guide. As a researcher in this area, I should appreciate the efforts put in to this book. The book can be used as a handbook of AI and Soft Computing for the students, researchers, and the teachers of this area. I strongly, recommend this book for the students of AI, which I have already done for my under graduate and graduate students.

While not a C programmer by any means, I decided to take some time and tackle the UNIX Network Programming book. I found that lots of early college classes came back to me as I forged a few pages in. It was clear from the very beginning that this book was going to be a very detailed study on all aspects of IP networking as it relates to UNIX programmers. Even for someone who isn't initiated in the topic or really even interested, it was quite an experience to read through the hundreds of flow charts and detailed examples of C code showing how to perform all kinds of interesting network tasks.

From a simple HTTP GET to detailed network file and connectivity operations, including TCP and UDP packets, ports, sockets and so on, there is a place in the book for each kind of network programming service. There is also a fair amount of text dealing with debugging techniques, allowing even those programmers who are experienced in their craft to find new ways to ferret out the problems in their code. The book also promotes good stylistics in programming, engendering the idea that readable and understandable code is better code than that which simply works.

There are also examples and explanations for IPv6?, for any programmer who is going to be making the leap into next generation networks. There are also instructions on how to deal with wireless networks, security models and other topics for anyone who plans on designing network applications or specialized network configurations.

It's probably not accurate to rate a book on a topic that holds little interest to the reader, but even a modest script programmer can tell when a book hits a subject just right and brings out all the details in a concise, easy-to-understand way. If you're a hard-core network programmer, this book is definitely for you. If not, you may find you learn something anyway.

It would be difficult to put value on a book that has been a classic text and a reference in academia and in the real world in the context of Network Programming for over a decade. Richard Stevens published the ever-popular Unix Network Programming [UNP] back in 1990, followed the second edition in 1998. With a dedication to the memory of R. Stevens, the UNP book found itself two new authors, Bill Fenner and Andrew M. Rudoff, who would write the third edition of this book. The third edition has many updates, a new look and feel and many of new chapters that cover the topics more applicable these days. In my opinion, it is still the most valuable and profound text in the context of Network Programming.

For those of us who have the first two editions of this book, the third edition has the following changes in effect:
·IPv6 updates. In the second version of the book, IPv6 was merely a draft and the sections covering IPv6 has been updated to take these changes into effect.

·POSIX updates. The functions/APIs and examples have been updated to reflect the changes to the latest version of the POSIX specification (1003.1-2001)
·SCTP coverage. 3 new chapters that cover this new reliable, message-based transport protocol have been added.
·Key Management Sockets coverage. Network security and its applicability and use with IPsec.
·Updated Operating Systems and machines that are used to run the examples in the book.
·Some topics such as Transaction TCP and X/Open Transport Interface have been dropped.

Many topics and sections have been updated with the authors' comments. These comments even though simple for someone new to the profession, are extremely useful as they are like hints and tips from one developer to the next to help you out in your next programming assignment.

If this is the only edition of the book that you are reading, you are in for a treat. Topics in Network Programming are covered in detail and using concrete programming examples that all of us can relate to - all Unix, but what else is there?! All kidding aside, the topics are covered well enough that they are useful information under any Operating System. The concepts don't change; sockets are sockets under any Operating System. The function call is different, but one needs to go thru the same steps under any environment.

Being the most popular networking protocol, TCP/IP is covered in Part I of the book. One needs to have prior understanding of the TCP/IP protocol and the OSI model, however. If this is the first time you are looking at the programming aspects of networking protocols, Part I of this book will cover the basics. It starts you off with a couple of simple examples such as daytime client and a daytime server and it builds on that as the reader reads along. TCP, UDP and SCTP (Stream Control Transmission Protocol) are covered in brief in Part I, and basic concepts such as the three-way handshake of TCP and the four-way handshake of SCTP are depicted.

Part II of the book covers sockets and socket programming. Topics such as the socket Address Structure in IPv4 and IPv6 for TCP, UDP and SCTP are covered and examples (the same daytime client/server) are given to convey the point to the reader. It is important to mention here that all the topics and concepts are depicted for the three transport protocols: TCP, UDP and SCTP. Every single socket API under the Unix programming environment is covered and examples are given for each function call to show the reader how the function can be utilized. An entire chapter has been dedicated to Socket Options and how they are used/can be used for best results. Hints are given throughout the chapter to tell the user about the pitfalls and best practices of each option.

After the basics have been covered, various I/O models are depicted in detail and examples are shown to convey the pro's and con's of each I/O model. The five I/O models used thru the book and available under the Unix environment are:
·Blocking I/O
·Non-blocking I/O
·I/O Multiplexing (using select and poll)
·Signal driven I/O
·Asynchronous I/O

SCTP - Stream Control Transmission Protocol, a new IEFT standard are covered in later chapters of 9 and 10 and again in chapter 23. The two interface models of SCTP (one-to-one and one-to-many) are covered in detail, and their differences with TCP are also explained in full. The client/server example that has been used throughout the book is ported to use the new SCTP protocol. The authors then go into great detail explaining the problems that SCTP solves over TCP and where and how it would be useful to use SCTP.

Advanced topics such as IPv4 and IPv6 portability, Unix Domain Protocols, Multicasting and advanced Socket programming for UDP, TCP and SCTP cover the rest of the chapters in this book.
Various options for interoperability between IPv4 and IPv6 start off the last section of the book. A chapter on Advanced I/O functions brings the reader a new perspective of how complicated Network Programming can become. Non-blocking I/O, befits and examples are covered in chapter 16. The topics on Multicasting, and adding reliability to UDP are probably my favorite chapters in this book. The Time Server that has been used throughout the book is re-coded to become a multicast application. Some issues that arise when designing multicast applications such as multicast on a WAN are also discussed.
The third edition of the UNP book is as good as ever. The updates truly reflect solutions to today's challenges in Network Programming. Bill Fenner and Andrew Rudoff did an amazing job continuing the work a true legend in the field of Computer Science.

The book was great. It covers both the basics for the TCP/IP API in Unix and some advanced techniques of Network Programming. The book was a very easy read and flowed great. There were plenty of code examples so you could read and see how the functionality would work. Besides this being a great reference tool for any Unix Programmer, it is a great tool for anyone looking to develop Unix apps with the new IPV6 standard. The book thouroughly covers both IPV4 and IPV6. When using it as a reference tool, the index is amazingly detailed. It makes finding the information your looking for quick and easy. This is one book that a Unix Programmer can't do without.

I have about 20 to 25 books on max and only 2 other books have valuted my skill level as high as this CD has done.
The CD plays great and flows at an excellent pace. Even the way they teach, gives you some great layout and operational techniques to make using MAX so much more efficient.
Plus what makes this training great is THE TUTOR. He is creatig the model at the same time as he is telling you what to do. Hence you always see his steps even if he skips mentioning it.
I have never been so pleased using one product as I have been using this CD.
As someone wrote earlier the CD is worth 3 times more than what we paid for it.

Wanderfull! I finally really doing it!
(what about character animation cbt?)

This CD has greatly improved my modelling skills and knowledge in max. It is like having a teacher there showing you and explaining every step, with the advantage of rewinding as many times as you need to. I would recommend this to the beginner of max modelling. It has certanily helped me out a long way. And Tim Kugler provides great support as well.

What are you waiting for, go buy a copy!

I am currently a student of Dr. Halpin at Northface University in Utah. After our first course on modeling in ORM directly from Dr. Halpin I am psyched about the future of DB modeling using ORM. This book along with "Database Modeling with Microsoft Visio for Enterprise Architects" serves as our core course books. Read this book and follow the Exercises and you are getting Halpin's Course minus his sense of humor.

His books are informative and easy to read. Even with his instruction close at hand, having this book is a must for any modeler who wants to get anywhere. He covers ORM, UML, and ER modeling. My preference for ORM when modeling databases or XML schema's is strongly tied to this book. Its easy, its fast, and best of all it makes sense.

My first recommendation would be to come check Dr. Halpin out for yourself in Utah @ Northface University. But if you can't, buy his books and seriously follow along. This is the future, this is where the industry is headed, not just for DB's but all applications (just ask anyone at MS or IBM).

This book is nothing short of brilliant. I read this book, did the exercises, and can honestly say its the best and most clearly written software development book I have read to date.

I started knowing nothing about how to design a database, and came away as an expert.

Halpin should win an award for this book.

After having used ER modeling with extreme frustration, I finally decided to investigate something new. This is the bible for ORM, and ORM is just so far superior to ER for conceptual modeling, which I now realize is critical.

Conceptual modeling means modeling your data in a way that makes sense to everyone, from the business experts (who know nothing about databases) to the coders and DBA's. And ORM provides a logical, intuitive way to do this.

Once you've got a conceptual model, it's pretty straightforward to get an ER model, from which you can develop the logical databased design. In fact, MS Visio (forget which version) does this for you.

The reason ER fails is that it cannot model data in a stable way. It still has a place, but ORM is so much more powerful, scalable, and stable.

And not only will you learn about ORM (he has great exercises to help practice), but you will learn a lot about data in general.

This is the best technical/developer/software engineering book I have ever read.

An excellent book for learning HTTP and much more about how web servers work at the protocol level. What you can learn in a few hours from this book is amazing because it is organized so well, the author is a gifted teacher with an excellent roadmap of what he wants to present, and the hierarchy of overview and detail is so well designed. The book covers the context in which the HTTP protocol resides, the details of HTTP itself, and then branches into important usages of HTTP for creating secure, reliable and scalable web sites.

Get this book. It reads a whole lot better than the spec. The language is so straightforward that your grandmother might enjoy reading it too. It comes with a dictionary of exception codes too, so you'll never be left scratching your head if a few important message packets begin to burp on their way to Paris via Kuala Lumpur.

I,as a university student with great interest to HTTP,borrow this book from school library. This book gives me basic and clear concept about http operations between client and server and stuff behind the scene. a list of explanation of http message and header is heleful too. later, the author writes very detail about proxy server,caching server and how the webserver are build for serious commercial use.
I am able to finish 2/3 of this book in 3 days. it's so interesting and keeps me reading on.

This is definitely a book to get you start with all kind of term for HTTP and a grasp for HTTP/Webserver concept.

for ppl with solid backgroud on HTTP, i would recommend the "HTTP: The Definitive Guide".

I have found this book of tremendous help in my work.

My first books on use cases focused more on UML rather than use cases. I did not give a hoot on use cases, because they look so simple on paper (and that's why I didn't buy a book specifically on use cases!) But as I grew as a developer, I began to believe that use case modelling if done well can significantly reduce development effort and bring about quality solutions. Use cases are the foundation to the understanding of the system that you are trying to develop. Use cases deserve serious attention.

The main problem with use cases is that you either don't know how to start or when to stop. This book tells you both. It tells you how to develop your use case model systematically from scratch and how to make provisions so that your use case model can grow. IMO, that's the main draw for this book.

The authors also give good insights on the possible approaches the reader can take to expand his/her use case model iteratively. It cautions the modeller to keep a balanced model so that stakeholders can understand, rather than one that specifies everything but gets bogged down by the details.

Semantics, you can get it elsewhere, but this book discusses it pretty well too. The examples are clear and relevant.

All in all, Frank and Granville did an excellent job covering the topic.

It is refreshing to a read a text that caters for those of use who already have experience in this domain and are seeking to develop their skills - without reverting to acadamia style writing. Useful examples, balanced descriptions, and an excellent coverage are all attributes of this text.

I strongly recommend this book!
