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.

Advantages of UniDAC

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.

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 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, macOS, Linux, iOS, and Android, 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.

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, producing dynamic SQL by replacing parts of the query statements with user-defined code.

Access to cloud services

UniDAC allows developing applications that work with data stored in cloud services such as BigCommerce, Dynamics 365, FreshBooks, Magento, Mailchimp, NetSuite, Salesforce, Salesforce Marketing Cloud, SugarCRM, QuickBooks, Zoho CRM. For this, it is enough to use UniDAC along with any Devart ODBC Driver for clouds.

Secure connection

You can use UniDAC with SecureBridge components to embed an SSL, SSH, or HTTP/HTTPS protocols into your application developed in Delphi, C++Builder, Lazarus, or Free Pascal for establishing a secure connection to the server.

Product features

Direct mode

Direct mode allows you to work with Oracle, SQL Server, MySQL, PostgreSQL, SQLite, Redshift, ASE, DBF, and NexusDB directly, without involving DB client libraries. This simplifies the deployment and configuration of your applications.

Mobile development

Development for iOS- and Android-powered mobile devices using UniDAC becomes easier than ever, as UniDAC allows your mobile applications to work with multiple databases as simply as desktop applications do.

Database compatibility

Our product supports the latest versions of the world's most popular database servers like Microsoft SQL Server, MySQL, Oracle Database, InterBase, Firebird, PostgreSQL, SQLite, and other databases (using ODBC providers) and cloud services.

IDE compatibility

Our product is compatible with the latest IDE versions and editions (including Community Editions): Embarcadero RAD Studio 13 Florence, Delphi 13 Florence, C++ Builder 13 Florence, Lazarus (and FPC). It is also compatible with the previous IDE versions since Delphi 6 and C++Builder 6.

Data type mapping

If you want to make custom correspondence between server and Delphi data types, you can use the simple and flexible data type mapping engine provided by UniDAC.

Development platforms

All major GUI frameworks are supported; you can develop VCL applications for Windows or cross-platform FMX applications in Delphi, as well as LCL applications for Windows, macOS, or Linux in Lazarus.

Performance

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.

Monitoring

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

FAQ

What is UniDAC?

Universal Data Access Components (UniDAC) is a powerful library of nonvisual cross-database data access components for Delphi, C++Builder, and Lazarus (Free Pascal). The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications. UniDAC completely replaces standard database connectivity solutions and is an effective alternative to Borland Database Engine and dbExpress for accessing databases and cloud services.

How to install Data Access Components in Delphi?

Before installing a new version of the Data Access Components you've chosen, uninstall any previous version you may have, and check if your new install is compatible with other Devart Data Access Components products you have installed.

To compile UniDAC-based applications, your environment must be configured to have access to the UniDAC libraries. Environment changes are IDE-dependent. For all instructions, replace %UniDAC% with the path to your UniDAC installation directory (for example, Delphi\Bin). To compile UniDAC-based applications, your environment must be configured to have access to the UniDAC libraries. Environment changes are IDE-dependent. For all instructions, replace %UniDAC% with the path to your UniDAC installation directory (Delphi).

What databases and cloud services are compatible with UniDAC?

UniDAC supports the latest versions of popular database servers like Oracle, SQL Server, MySQL, InterBase, Firebird, PostgreSQL, SQLite, and others (using ODBC provider) as well as different cloud services like Freshbooks, Google BigQuery, Netsuite, and Salesforce.
