Book Description

March 20, 2006 1590596323 978-1590596326 2

Rockford Lhotka started writing his Business Objects books in 1996, and over the years, he’s become one of the world’s foremost authorities on building distributed object-oriented systems. His industry-standard VB .NET Business Objects book not only addresses changes in .NET 2.0 and Visual Studio 2005, but also reflects substantial enhancements and improvements to the CSLA .NET Framework and how it can be used to create enterprise-level .NET applications.

Expert C# 2005 Business Objects is for developers who want to see Lhotka's ideas applied in the C# idiom. The book takes you from an opening discussion of logical architectures to detailed n-tier deployment options using the CSLA .NET Framework.

The depth of Rockford's thinking now influences developers across language boundaries. With this book, you can learn directly from the expert whose framework has become universally accepted and respected.

Format:Paperback
Truly, I think this book is an introduction to Mr. Lhotka's CSLA Framework, and not a text for designing expert business objects. Discovering and designing business objects for an application are tough exercises that are not covered in much detail here.

There are applications that can benefit from the type of design suggested in the book and the CSLA framework, but in the realm of business applications I think they are few and far between. If you want to build an application that essentially pulls records from a database, lets the user view or change that data and return it to the database, then this book offers a very straightforward way to build these types of applications. However it is easy for a developer to believe that this type of design can be applied to every application they face. (When you have a hammer, everything looks like a nail.) Often, I think the result is an application highly coupled to the implementation of storage, with quasi-business objects that have complexity above and beyond their true business complexity, no core system that can be cleanly modeled and understood by non-technical team members, and a user interface that is often no more than just a front-end to a database. Again, I think the CSLA framework promotes this kind of design; it does not enforce it or stop you from building a more solid design.

The book is well written and is not too difficult to follow the concepts offered. This is why I give it 3 stars and not less. However I have to warn the newer developer who is looking for guidance in building OO designed applications in an effort to manage the difficulties of the more complex business applications they are starting to deal with. I don't think this book addresses this need. I would suggest Object-Oriented Design Heuristics by Arthur J.

3.0 out of 5 stars GOOD INFORMATION, ARCHITECTURE SO/SO February 13, 2007
Format:Paperback
This book has a very good discussion of frameworks and includes the details of the CSLA (Component Scalable Logical Architecture) framework. However, I don't believe the book is worthwhile for the discussion of frameworks alone. If you're required to use CSLA, then this is the book for you.

I give the book three stars because its contents can't be separated from the design of CSLA. The problem with CSLA is the layers. The use of "fat", fully encapsulated business objects has fallen out of favor recently and is not the best architecture for enterprise applications. Despite what the author says, I don't believe CSLA is truly a layered architecture, either.

The book lacks a discussion of when CSLA is a good choice and when another architecture is better. Choosing to use CSLA pre-determines your architecture (the "A" stands for "Architecture", after all). You should always choose your architecture based on your requirements and never select an architecture in advance.

That said, CSLA can be a good architecture for smaller projects. New developers often have issues understanding true multi-tiered architectures. Because CSLA uses an encapsulated architecture that's similar to the OOP training they had in school, those developers may find CSLA a good choice because it's easier for them to understand.

1.0 out of 5 stars CSLA is behind the times February 16, 2009
By Fred
Format:Paperback
I have tracked CSLA and used the architecture since the Early VB6 days and I unfortunately have to admit that I have moved from being a follower to becomming increasingly dissapointed over the years. CSLA has in my opinion just failed to keep up with the newer concepts of Domain Modelling etc from Eric Evans it has also failed to in incorporating concepts and patterns from Martin Fowler et al. The architecture does not solve or present any real solution for the Object Relational mapping issues etc etc etc. The problem in my opininion stem from the fact that the architecture has remained rooted in the principles that worked and were needed in VB6. If you and your organisation are already committed to CSLA then keep buying the book and keep up with the minor changes that happen to the architecture with each iteration. The second problem for me is that the CSLA is not test driven (although there are some tests that appear to have been retrofitted). The Framework itself is fairly limited with most of the logic being in the generated code. This means that it is extremely difficult to extend or enhance since you need to start fiddling with templates etc. We all know that generated code is very hard to test so doing this makes things very fragile and frustrating.

If you are looking learn Domain Concepts and to utilise these in production projects then I would suggest that you go for one of the Open Source Enterprise Application Frameworks that are available. These are more feature rich and more alive in terms of contribution than CSLA.

My suggestions would be
1)NHibernate - this is an open source ORM but has many generators e.g. CodeSmith that allow you to generate the Business Object Layer.

5.0 out of 5 stars Great Book for understanding Frameworks November 12, 2006
Format:Paperback
I found this book to be a great book to learn the ins and outs of designing and implementing a Business Framework, and how to implement real world OOP. I have had a lot of trouble in the past reading all the examples in books about OOP in general. They would start off with the analogy of a car, an airplane, a person, etc. a lot of detail would go into designing that object. All well and good but how do I really break down these objects so they can be used in a business model and extend that same object. Well this book has moved me a long way down the road in that regard. I have had the privilege of seeing Rocky at a training event. This book is not a hypothetical to him but real world knowledge put into practice.
