SQL Server Data Access Components (SDAC) is a library of components that provides access to Microsoft SQL Server databases. SDAC connects to SQL Server directly through OLE DB, which is a native SQL Server interface. The SDAC library is designed to help programmers develop faster and cleaner SQL Server database applications. SDAC is a complete replacement for standard SQL Server connectivity solutions and presents an efficient alternative to the Borland Database Engine for access to SQL Server.

Components
All editions of SDAC include the following basic components:

• TMSConnection - lets you set up and control connections to SQL Server
• TMSQuery - queries execution, operates record set, flexible way updating database tables
• TMSTable - lets you retrieve and update data in a single table without writing SQL statements
• TMSStoredProc - executes stored procedures and functions
• TMSSQL - executes SQL statements and stored procedures, which do not return rowsets
• TMSScript - executes sequences of SQL statements
• TMSUpdateSQL - lets you tune update operations for a DataSet component
• TMSDataSource - provides an interface between a SDAC dataset components and data-aware controls on a form
• TMSSQLMonitor - allows to monitor dynamic SQL executing in SDAC based applications
• TMSConnectDialog - allows you to build custom prompts for usernames, passwords, and servers
• TVirtualTable - dataset stores data in memory
• MSDataAdapter - .NET component, uses TDataSet as data source for retrieving and saving data to System.Data.DataSet

• TMSLoader - allows you to quickly load data into SQL Server databases
• TMSDump - serves to store a database or its parts as a script and also to restore database from received script
• TMSServiceBroker - lets you work with Service Broker technology to send and receive messages
• TMSMetadata - allows to retrieve embracing metadata on specified SQL object
• TMSChangeNotification - lets you react on different server side changes on-the-fly. Based on the Query Notifications mechanism of SQL Server 2005
• TMSTransaction - lets you control distributed transactions via Microsoft Distributed Transaction Coordinator
