2 Question about Enterprise Library 2.0

rockdale

Well, I guess I did express myself very clearly.

I implemented the Ent Lib 2.0 data block against SQL database
successfully. The system now is a production system. But now we want to
migrate the database to MySQL. From mySQL website you can find
Connector/Net 1.0 and COnnector/ODBC, further more this link talks
aboout
http://dev.mysql.com/tech-resources/...x.html#ADO.NET
different approaches to connect to mySQL.
My question is which one should I use so that my coding change is
minimum. I guess if I use ODBC then what I need to change is the
connectionstrin g in my web.config file. But ODBC may not be the best
choice since it is slow? For Connector/Net1.0 I am not sure wether Ent
Lib 2.0 support it or not.
My second question is how can I encrypt the connectionstrin g in my
web.config file to protect user credential and at the same time the ENt
Lib 2.0 can use the decrypted connectionstrin g. (where should I decrypt
the connectionstrin g?)

Sorry for the confusing first post

Thanks again

You want to avoid the ODBC if you can. It introduces more layers, something
affecting performance.

The big scoop with ODBC (circa late 1990's) was that it allowed a common
syntax between different vendors.
But, you paid the price for this generic-ness.

However, you have a bigger question.

Has someone extended the 2.0 Enterprise Library for use with MySql? I don't
know the answer to this.

http://www.aspfree.com/c/a/ASP.NET/C...ing-ASPNET-20/

a.. Database (the abstract class)
a.. SqlDatabase
a.. OracleDatabase
a.. GenericDatabase
You see, someone has created a "concrete" class for Sql Server, called
SqlDatabase.
Someone has created a concrete class for Oracle, called OracleDatabase

the question is... has someone out there in internet-land wrote one for
MySql.
as in, they wrote a concrete class (which works specifically with MySql)
which implements:
Microsoft.Pract ices.Enterprise Library.Data.Da tabase

Or can you use the GenericDatabase object?

I'm not a MySql person, so I don't know the answers.

Your post:
http://dev.mysql.com/tech-resources/...x.html#ADO.NET

This articles shows how to talk to MySql thru DotNet, this is not an
extension of the EnterpriseLibra ry (for MySql)

Try here
http://www.codeproject.com/useritems...th_Ent_Lib.asp

which I found by googling:
"Microsoft.Prac tices.Enterpris eLibrary.Data" MySql
