SQL Server Data Access Components (SDAC) library offers a set of
nonvisual components for Borland Delphi and C++ Builder. They
provide access to Microsoft SQL Server and are an alternative to a
standard way of accessing databases using Borland Database Engine
(BDE).
SDAC uses OLE DB directly through a set of COM-based interfaces
that expose data from a variety of sources. OLE DB interfaces
provide applications with uniform access to data stored in diverse
information sources, or data stores. These interfaces support the
amount of DBMS functionality appropriate to the data store,
enabling the data store to share its data.
Using BDE in MS SQL Server oriented client/server applications has
some deficiencies. In many cases BDE community are unable to
employ server specific features, they must tolerate excessive
usage of resources, reduced speed of processing data, restricted
distribution of an application and its administration.
