The Enterprise Library seems to have a lot of good stuff in it. However, am
I missiing something, or is the Data Access Application Block JUST for
Oracle, SQL server & DB2. What about OLEDB for Access DBs????

Hi,

I am pretty sure you can extend it to support OleDB by implementing several
provider-specific classes (and making changes to the provider factory in
order to recognize the new provider type).

Microsoft at its best.

Why have they left out the most flexible provider: OleDb ?!

I am sure the Entrerprise Library DAAB can be extended to support OleDb, but
they should have provided the support for it from the get-go.

I am sure it is a great academic exercise to complete the DAAB but how much
time and costs am I really going to save introducing these entreprise library
blocks in my development if I have to extend them before using them ? I mean,
this is not some dark custom provider, it is OleDb!

Makes me wonder if this is a pattern I can expect from the rest of the
Enterprise Library Blocks.

....actually I was surprized not to find a provider using Odbc, since
they added the Odbc namespace to the framework in v.1.1 :(

Hopefulyl we will soon find tutorials on how to extend the EL so that
we can make our own.

ANyone found good samples on that yet?

I've been reading all I could find in the GotDotNet Workspace, but I
haven't found yet any 'How to extend the EL for dummies' article yet :(

F.O.R.
