ODBCDAC for Delphi

Posted on by Robin Ding Leave a comment Design, Libraries

ODBC Data Access Components (ODBCDAC) is a feature-rich and high-performance library of components that provides data access for data sources exposed through ODBC. The components support both 32-bit and 64-bit platforms. ODBCDAC-based applications connects to any data source exposed through ODBC using the .NET Framework Data Provider for ODBC.ODBCDAC aims to assist programmers in developing of fast and native database applications. ODBCDAC uses the native ODBC Driver Manager (DM) to enable data access. ODBCDAC uses the native ODBC Driver Manager (DM) to enable data access.

ODBCDAC-based DB applications are easy to deploy, requires installation of ODBC drivers, uses ADO.Net technologies and works faster than the ones based on standard Delphi data connectivity solutions.
