Forking this subquestion from my question
Does SQL Server clients use (WDAC, MDAC) and when?
Having read msdn article SQL Server 2008 R2 Native Client Programming I could not understand:
Is SQL Server Native Client (SSNC) intended to be used as advanced substitute for MDAC (currently renamed as WDAC)?
what one could have understood from th? article...
Except that this article tells:
"The SQL Server Native Client ODBC driver is always used in conjunction with the ODBC Driver Manager supplied with Windows DAC"
From one side it sounds that SQL Server Native Client (SSNC) provide the same functionalities that MDAC (WDAC) and more being "a stand-alone data access API,".
From the other side, it is written that SSNC is dependent on MDAC(WDAC) components (drivers, dll) and vice versa.
So, why 2 parallel, having essentially the same functionalities, data access structure duplicates?
