daab

DAAB stands for Data Access Application Block, a proprietary Microsoft technology that is part of the Microsoft .NET framework. It is a software component for accessing stored procedures and issuing textual SQL queries -- for MS SQL Server databases. DAAB supports the languages C# and Visual Basic .NET. It is quite akin to JDBC (Java Database Connectivity) as in both cases you pass in text strings of SQL commands to access a database. While JDBC is aimed at portability, DAAB is specific to MS SQL Server.

DAAB can also be viewed as a basic Object Relational Mapping tool, that simplifies simple developments. Where DAAB is perhaps not the best choice is where more sophisticated relationships are involved such as "Order" linking to many "Order Lines". Whereas frameworks such as J2EE separate business logic from presentation, in .NET (and hence in DAAB) the two are much more tightly coupled. As the stored procedure languages of Oracle and MS SQL Server are different, so DAAB 1.0 and 2.0 code was limited to SQL Server. DAAB 3.0 is anticipated to support both.

DAAB is also the name of a polish Reggae-Band.
