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, 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.
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.
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.
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
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, 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
native applications for Windows and Mac OS X.
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.
Allows your application to work with Oracle, MySQL, PostgreSQL, SQLite, and NexusDB
directly without involving a DB Client library, thus significantly facilitating
deployment and configuration of your applications.
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)
UniDAC doesn't limit your choice of the development platform. Now you can develop
for 32-bit and 64-bit platforms with Delphi and Lazarus (FPC).
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.
Our product is compatible with the latest IDE versions: Embarcadero RAD Studio XE4,
Delphi XE4, C++Builder XE4, Lazarus (and FPC). It is also compatible with the previous
IDE versions since Delphi 6 and C++Builder 6.
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
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,
