Provide data access to SQL Server databases from your VCL applications. SQL Server Data Access Components (SDAC) library offers a set of nonvisual components for Delphi and C++ Builder. They provide access to Microsoft SQL Server and are an alternative to the 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.

Using BDE in database applications amounts to the following data path between server and client:

[SQL Server] <-> [DBLibrary] <-> [SQL Links] <-> [BDE] <-> [Application]

SDAC works directly through OLE DB, which is a native MS SQL Server interface. Applications with SDAC components access server directly:

[SQL Server] <-> [OLE DB] <-> [Application]

SDAC includes following components:

TMSConnection - controls server connection;

TMSQuery - queries execution, operates record set, flexible way updating database tables;

TMSSQL - executes SQL statements;

TMSTable - allows to retrieve and update data single table without writing SQL statement;

TMSStoredProc - executes stored procedures and functions;

TMSSQLMonitor - allows to monitor dynamic SQL executing in SDAC based applications;

TMSConnectDialog - serves for enter username, password and server name;

TMSMetaData - allows to retrieve embracing metadata on specified SQL object;

TVirtualTable - dataset stores data in memory.

Only Professional, Enterprise and Architect editions are supported.

SQL Server Data Access Components comes in two editions: SDAC Standard Edition and SDAC Professional Edition.

SDAC Standard Edition includes the SDAC basic connectivity components and the SDAC Migration Wizard. SDAC Professional Edition includes additional components.

Following are the main features of SQL Server Data Access Components:

No distribution, installation and configuration is required for BDE and ODBC;

You can use any Delphi Professional Edition to develop client/server applications;

VCL and VCL.NET versions of library

Supports MS SQL Server specific features: windows authentication, metadata, unicode fields, manual refresh for record in a dataset, automatic getting Identity value and results of triggers work and a lot of more;

Simplifies data updating;

Speeds up fetch of records from database;

Provides automatic refresh for records;

Advanced design time editors;

Interface (methods, properties) of SDAC components is similar to those of standard BDE data access components (TDatabase, TQuery, ..);

Extended SQL tracing capabilities provided by TMSSQLMonitor component and DBMonitor application;

Includes source code of TCRDBGrid enhanced data-aware grid control;

Wide data-aware and reporting components support, including InfoPower, ReportBuilder, FastReport;

and many other features.
