Question

What problems would I have had to come up against for me to turn to Microsoft Enterprise Library for its DAAB? In other words, I seem to be developing fine without it now – I’m using ADO .net entity framework to access my SQL database but obviously open to new/more efficient ways of dealing with data access if they’re worth it. The only articles I seem to have found are aimed at the more senior level of developer so can anyone please give me a little explanation of what Enterprise Library actually provides that I may be missing out on now??

Answer 1

When you are coding you should never re-event the wheel for many reasons. Most importantly when you re-use you are using something that has been reviewed and generally accepted by the development community. EL is library is designed to simplify the amount of code you need to write to do common things like exception handling, data access, logging, etc.

In the case of Data Access Application of the many benefits:

1. it forces you to abstract your self from the underlying database and types allowing you to move from one to another. This also forces you to standardize how your access your data in your product.
2. DA also allows you to simply define your database and access it in a generic fashion, leaving DA to deal with the plumbing of connecting and querying your database.
3. Lastly it also helps junior level developers because they dont have to code to different databases, they use one interface and it will work on various platforms.

Drawbacks, in general any framework that sits above ADO.NET will be slower, and if you are not planning on doing any of the above, you might not need to use it.
