dbExpress Drivers

dbExpress is a database-independent layer that defines 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 data-access layer is thin and simple, dbExpress provides high performance database connectivity and is easy to deploy. You can use our drivers in the same way as the ones supplied by Embarcadero.

We offer lightweight dbExpress drivers for access to the following database servers:

Advantages of our dbExpress drivers

Devart dbExperss drivers offer a set of advantages in comparison with the standard drivers supplied by Embarcadero. Along with advanced stability, functionality, and efficiency they present the most optimal way to access data of all similar solutions available on the market, and also the ability to connect through native protocol without using client software. Among other advantages, we can name:

Direct access to data

We offer you optimal data access using native libraries. Devart dbExpress drivers for Oracle, MySQL, and PostgreSQL are able to connect through the native protocol without using client software.

High performance

Use Devart dbExpress drivers if you need to develop fast and efficient data access applications.

Support for the latest versions of servers

Devart dbExpress drivers support latest versions of Oracle, MySQL, PostgreSQL, Microsoft SQL Server, Interbase, Firebird, and Yaffil.

All data types support

Our dbExpress drivers support all the data types, which may be mapped to dbExpress data types. Besides, our dbExpress drivers have additional options to control data type mapping, such as EnableBCD option, which allows the driver to map NUMERIC, DECIMAL, BIGINT datatypes on ftFMTBcd field type.

Extended options for advanced behaviour

Devart dbExpress drivers offer several extended options that expand functionality of the driver. For example, Prepared option allows all dataset to be prepared. Reconnect option controls if automatic reconnect should be performed if the connection is broken.

Complete support for dbExpress version 4

Our drivers are completely compatible with the dbExpress version 4 and can be used in applications, developed with CodeGear RAD Studio 2007 and later without any performance or feature loss.

Ability of monitoring query execution with dbMonitor

dbMonitor eases the debug process, allowing you to view the application database interaction log. You can monitor all the executed SQL Statements, connect/disconnect and transaction events and view SQL statement execution status, database error messages, parameters with their values.

Source code available

You may order edition with source code. It can be useful for debugging and locating errors, or if you need to change something in our drivers for your applications.

Easy to deploy

You need to deploy just a single additional dll with your application, using dbExpress drivers.

Include annual Subscription with Priority Support

Subscription Program is an annual maintenance and support service for users of Devart dbExpress drivers.

It grants every user free access to the latest drivers' versions when they are released, access to all updates and bug fixes of the driver, product support through the Priority Support program, and notifications on new product versions.

Priority Support is an advanced product support program which offers you expedited individual assistance with product-related questions from the developers themselves. Priority Support is carried out over email and has a two business day response policy.

Licensed royalty-free per developer

The drivers don't require payment of author's royalty, and their license gives right to use the drivers for software development.
