Components
IBDAC includes the following components:

• TIBCConnection - sets and controls connection to InterBase database
• TIBCTransaction - provides discrete transaction control over database connections
• TIBCQuery - uses SQL statements to retrieve data from InterBase table or tables, automatically generates missing INSERT, DELETE, UPDATE statements
• TIBCTable - lets you retrieve and update data in a single table without writing SQL statements
• TIBCStoredProc - executes stored procedures and functions, allows to edit cursor data returned as parameter
• TIBCSQL - executes SQL statements and stored procedures, which do not return rowsets
• TIBCScript - executes sequence of SQL statements
• TIBCUpdateSQL - lets you tune update operations for a DataSet component
• TIBCDataSource - provides an interface between a IBDAC dataset components and data-aware controls on a form
• TIBCAlerter - transfers messages between connections
• TIBCMetaData - retrieves metadata on specified SQL object
• TIBCSQLMonitor - allows to monitor dynamic SQL executing in IBDAC-based applications
• TIBCConnectDialog - serves for entering username, password and server name
• TCRDBGrid - extends TDBGrid capabilities, provides visual access to filters and incremental search
• TVirtualTable - dataset stores data in memory
• IBCDataAdapter - .NET component, uses TDataSet as data source for retrieving and saving data to System.Data.DataSet
• TCRBatchMove - transfers data between all types of TDataSet descendants
