dbExpress is a database-independent layer that defines common interface to provide fast access to PostgreSQL from Delphi and C++Builder, including Community Edition, on Windows and macOS (32-bit and 64-bit) and Linux (64-bit) platforms. For this server, dbExpress provides a driver as an independent library that implements the common dbExpress interface for processing queries and stored procedures. As data-access layer is thin and simple, dbExpress provides high performance database connectivity and is easy to deploy. You can use our driver in the same way as the one supplied by Embarcadero.
dbExpress driver for PostgreSQL provides direct high performance access to PostgreSQL database server. It directly connects to the server without using PostgreSQL client software.
Native Connectivity to PostgreSQL
Applications based on dbExpress driver for PostgreSQL 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, PgDAC provides an additional opportunity to work with PostgreSQL directly via TCP/IP without involving PostgreSQL Client.
