Universal Data Access Components

Universal Data Access Components (UniDAC) is a library of components that provides direct access to multiple databases from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. We have combined the experience of long-term successful development into one product, which provides unified access to multiple database servers like Oracle, Microsoft SQL Server, MySQL, InterBase, Firebird, PostgreSQL, SQLite, DB2, Microsoft Access, Sybase Advantage Database Server, Sybase Adaptive Server Enterprise, and other databases (using ODBC provider).

UniDAC offers unified approach to the database-related applications development process. That means you can switch easily between different databases in your projects without going deep into their specifics.

Using UniDAC with its server-independent interface is the best way to create cross-database applications. UniDAC gives outstanding flexibility and independence to your projects.

Advantages of UniDAC Technology

UniDAC is easy to setup and use. It provides transparent server-independent interface for working with different databases. Selected database provider ensures the best way to perform operations on the server.


Unified Connectivity Solution

UniDAC provides transparent server-independent interfaces for working with different databases, and lets you change the client engine for a specific server type just by changing single connection option. It means that you can easily switch between different database servers in your cross-database UniDAC-based application.

Server-Aware Providers

Server-Aware Providers

UniDAC chooses the best way specific to the server to perform most operations. Every UniDAC data provider uses server-specific native connectivity. All operations with data are performed by providers automatically considering the selected database server peculiarities.

Cross-platform and cross-IDE solution

Cross-Platform Solution for Delphi, C++Builder, and Lazarus

UniDAC is a cross-platform solution for developing applications using various IDEs: RAD Studio, Delphi, C++Builder, Lazarus (and FPC) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both x86 and x64 platforms. UniDAC also provides support for the FireMonkey platform, which allows you to develop visually spectacular high-performance desktop and mobile native applications.

Optimized Code

Server-Independent SQL

When developing database applications that allow working with several databases, one of the key points is writing of server-independent SQL. In UniDAC, the server-independent SQL support is implemented by means of the powerful macros engine, that produces dynamic SQL by replacing parts of the query statements with user-defined code.

Key Features

Direct Connection

Direct Mode

Allows your application to work with Oracle, SQL Server, MySQL, PostgreSQL, SQLite, and NexusDB directly without involving a DB Client library, thus significantly facilitating deployment and configuration of your applications.

x64 development

Mobile Development

Develompent for iOS and Android mobile devices using UniDAC becomes still easier, as UniDAC allows your mobile applications to work with multiple databases as simply as desktop applications do.

Database Compatibility

DB Compatibility

Our product supports the latest versions of the popular database servers like Oracle, SQL Server, MySQL, InterBase, Firebird, PostgreSQL, SQLite, and other databases (using ODBC provider)

IDE Compatibility

Data Type Mapping

If you want to make custom correspondence between server and Delphi data types, you can use a simple and flexible Data Type Mapping engine provided by UniDAC.

IDE Compatibility

IDE Compatibility

Our product is compatible with the latest IDE versions: Embarcadero RAD Studio 10 Seattle, Delphi 10 Seattle, C++Builder 10 Seattle, Lazarus (and FPC). It is also compatible with the previous IDE versions since Delphi 6 and C++Builder 6.

IDE Compatibility

Development Platforms

Now you can develop not only VCL-based applications in Delphi and LCL-based ones in Lazarus, but also use the newest FireMonkey application development platform.



All our components and libraries are designed to help you write high-performance, lightweight data access layers, therefore they use advanced data access algorithms and techniques of optimization.



Use our freeware dbMonitor tool to monitor and analyze all the DB calls made by your application using UniDAC. dbMonitor performs per­component tracing of SQL statement execution, commits, rollbacks, etc.

Steve Faleiro, Delphi Developer from Goa, India

I just wanted to say thanks to the Devart team for a great product. UniDac succesfully compiled on my linux X64 box with Lazarus / FPC and it also succesfully compiled on my Raspberry Pi with Lazarus / FPC. Well done guys I am really impressed.
