Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, Delphi for .NET, C++Builder, and Lazarus (Free Pascal).

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, SAP Sybase Advantage Database Server, SAP Sybase Adaptive Server Enterprise and other databases (using ODBC provider).

Key Features:

  • 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.
  • 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.
  • DB Compatibility: The 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)
  • 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: Our product is compatible with the latest IDE versions: Embarcadero RAD Studio 10.2 Tokyo, Delphi 10.2 Tokyo, C++Builder 10.2 Tokyo, Lazarus (and FPC). It is also compatible with the previous IDE versions since Delphi 6 and C++Builder 6.
  • Development Platforms: Now you can develop not only VCL-based applications in Delphi and LCL-based ones in Lazarus, but also use the newestFireMonkeyapplication development platform.
  • Performance: All the 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 optimisation.
  • Monitoring: Use Devart's freeware dbMonitor tool to monitor and analyse all the DB calls made by your application using UniDAC. dbMonitor performs percomponent tracing of SQL statementexecution,commits, rollbacks, etc.
  • Support: Visit Support page to get instant support from experienced professionals, fast and detailed responses, user engagement and interaction, frequent builds with bug fixes and much more.

Universal Data Access Components (UniDAC) - Features

Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, Delphi for .NET, C++Builder, and FreePascal. We have combined the experience of long-term successful development into one product, which provides unified access to the popular database servers like Oracle, Microsoft SQL Server, MySQL, InterBase, Firebird, and PostgreSQL.

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

  • Universal Data Access
    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 database servers in your cross-database UniDAC-based application.
  • 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.
  • Optimized Code
    The goal of UniDAC is to enable developers to write efficient and flexible database applications. The UniDAC library is implemented using advanced data access algorithms and optimization techniques. Classes and components undergo comprehensive performance tests and are designed to help you write high-performance, lightweight data access layers.
  • Compatibility with Standard Data Access Components
    The UniDAC interface retains compatibility with the standard VCL data access components like BDE. Existing BDE-based applications can be easily migrated to UniDAC and enhanced to take advantage of the server-specific features.
