Oracle Data Access Components (ODAC) is a library of components that offers native connectivity to Oracle in Delphi and C++Builder, such as Community Edition, in addition to Lazarus (and Free Pascal) on Windows, Linux, macOS, iOS, along with Android for both 32-bit and 64-bit platforms. The ODAC library is intended to help developers develop quicker and more native Oracle database software.
ODAC, a high speed, and feature-rich Oracle connectivity alternative, would be an efficient native option to the Borland Database Engine (BDE) and regular dbExpress driver. It supplies both chances of connection with Oracle through native Oracle data access and immediate access to Oracle from Delphi with no Oracle Client.
ODAC-based DB software is simple to deploy. It doesn't require the installation of different information supplier layers (for example, BDE or ODBC), so they can operate faster than the ones based on standard Delphi data connectivity options. Additionally, ODAC offers an extra chance to utilize Oracle directly through TCP/IP without requiring Oracle Client.
