Oracle Data Access Components (ODAC) library offers some nonvisual components for Borland Delphi. They serve for access to Oracle RDBMS. ODAC is an alternative to standard way processing data by Borland Database Engine (BDE). Using Oracle Data Access gives you the following advantages: - No distributing, installing and configuring the BDE and ODBC; - You can use any Delphi Professional Edition to develop client/server application; - Enables you to use many Oracle specific features; - Simplifies data updating; - Speeds up fetch record from database; - Provides automatic locking and fefreshing records; - Allows to execute longtime stored procedure separated thered; - Supports BLOB-fields; - Interface (methods, properties) of ODAC components is similar to standard BDE data access components (TDatabase, TQuery, ..); - Supports all data-aware components.
