Whether youвЂ™re fortunate enough or not to be in such a situation (sometimes lawyers get in the way, sometimes clients arenвЂ™t available for that much commitment, etc.) itвЂ™s important to understand what everyone brings to the table. In fact, whenever possible, I donвЂ™t see it as the development team and the client, but a single entity: the team. Something which I take very seriously from Agile development is the close interaction the development team has with clients and users. Not only that, but it was their money and my job was to make them get the most out of it.ДЄs the relationship turned more collaborative and positive, not only did the end result greatly improve, but programming became fun again. The client knew far more about his or her business than I did. Once I actually thought about it though, I realized that I wasn't nearly as smart as I thought I was. They were annoying, didn't know what they wanted and always made the wrong choice. In the past, I'd frequently get pissed off with clients. NET community, are probably scratching their heads trying to understand why Microsoft insists on going against conventional wisdom and clumsily having to always catch-up.) Many programmers, both inside and outside the. NET developers are doing (enterprise development), and, when improperly used, results in less maintainable code. I think much of the hostility between the вЂњcampsвЂќ is that Microsoft disproportionately favors data driven design despite the fact that it doesnвЂ™t fit well with what most. True ALT.NETers though, ought to appreciate that data driven is indeed the right choice in some situations. (It may be crude and a little contradictory to what I said in my introduction, but the debate between The MSDN Way and ALT.NET could be summed up as a battle between data driven and domain driven design. YouвЂ™ve probably read all of this before, and in the end, you simply have to make a leap of faith and tentatively accept what we preach вЂ“ at least enough so that you can judge for yourself. This doesnвЂ™t make domain driven better than data driven вЂ“ it simply makes domain driven better than data driven in some cases and the reverse is also true. DDD is simply better suited at handling complex systems in a more maintainable way for a number of reasons вЂ“ all of which weвЂ™ll cover in following chapters. A data-centric system isnвЂ™t void of behavior nor does it treat them as an afterthought. Of course that isnвЂ™t at all the case вЂ“ in fact itвЂ™d be pretty trivial to do. The above descriptions are somewhat misleading вЂ“ it somehow implies that if you were using DataSets you wouldnвЂ™t care about, or be able to provide, the behavior of giving employees a raise. The tool we use is object oriented programming (OOP) вЂ“ and just because youвЂ™re using an object-oriented language like C# or VB.NET doesnвЂ™t mean youвЂ™re necessarily doing OOP. The Problem Domain is just a fancy way of saying the business youвЂ™re building a system for. So we not only focus on the fact that an employee has a FirstName, but also on the fact that he or she can get a Raise. This approach is sometimes called data driven development.Дomain-centric design or, as itвЂ™s more commonly called, domain driven design (DDD), focuses on the problem domain as a whole вЂ“ which not only includes the data, but also the behavior. The focus is all about the data вЂ“ which in a lot of cases is actually a good idea.

We all know that given a table with data in it, we can have a website or windows application up and running in less than 5 minutes with just a few lines of code. NET developers is that Microsoft spent a lot of time automating the mimicking process with DataAdapters, DataSets and DataTables. The typical approach is to first model your database by creating all the tables, columns and foreign key relationships, and then mimicking this in C#/VB.NET. What do I mean by data and domain-centric approaches? Data-centric generally means that you build your system around your understanding of the data youвЂ™ll be interacting with.
