Oracle Data Access Components

MORE DELPHI COMPONENTS

Oracle Data Access Components (ODAC) is a library of components that provides native connectivity to Oracle from Delphi and C++Builder including Community Edition, as well as Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms. The ODAC library is designed to help programmers develop faster and more native Oracle database applications.

ODAC, a high-performance and feature-rich Oracle connectivity solution, is an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver. It provides both possibility of connection to Oracle by means of native Oracle data access and direct access to Oracle from Delphi without Oracle Client.

Native Connectivity to Oracle

ODAC-based DB applications are easy to deploy, do not require installation of other data provider layers (such as BDE or ODBC), and that’s why they can work faster than the ones based on standard Delphi data connectivity solutions. Moreover, ODAC provides an additional opportunity to work with Oracle directly via TCP/IP without involving Oracle Client.

General usability

• Direct access to server data. Does not require installation of other data provider layers (such as BDE and ODBC)
• Interface compatible with standard data access methods, such as BDE and ADO
• VCL, LCL and FMX versions of library available
