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.
