dbExpress is a database-independent layer that defines a common interface to provide fast access to SQL database servers. For each supported server, dbExpress provides a driver as an independent library that implements the common dbExpress interfaces for processing queries and stored procedures. As a thin and simple data-access layer, dbExpress provides high performance database connectivity and is easy to deploy. dbExpress driver for InterBase (DbxIda) provides access to InterBase, Firebird and Yaffil databases. It directly uses InterBase client software to connect to server. DbxIda supports InterBase starting with the version 5.x, Firebird 2.x, 1.x versions and Yaffil. Driver requires InterBase client to be installed on the client side. Following the main features of our dbExpress drivers: * Direct data access * Ability to connect through native protocol without using client software (DbxOda and DbxMda) * High performance * Supports latest versions of servers * All data types support * Extended options for advanced behaviour * Ability of monitoring query execution with DBMonitor * Source code available * Free support for registered users * Licensed per a developer without royalty fee
