Getting Started with UniDAC
Universal Data Access Components (UniDAC) provide a framework for building database applications that work with different database servers through a unified programming interface. The library enables developers to manage connections, execute queries, and work with datasets using consistent components while supporting database-specific functionality where required.

Multi-Database Connectivity

Provides connectivity to a wide range of database systems including Oracle, SQL Server, MySQL, PostgreSQL, SQLite, InterBase, and Firebird through a unified programming interface.

Direct Database Connection Mode

Supports direct connectivity to several database servers without requiring external client libraries, simplifying application deployment and configuration.

Stored Procedure And Function Execution

UniDAC provides components for executing stored procedures and functions across supported database systems. Applications can pass parameters, retrieve result sets, and integrate database side logic into application workflows while maintaining a consistent programming interface.

Server-Aware Database Providers

Uses database-specific providers that optimize data access operations according to the connected database server.

Server-Independent SQL Support

Includes SQL macros and query customization tools that help developers write flexible SQL statements for applications that work with multiple database systems.

Secure Database Connectivity

Supports encrypted connections and secure communication protocols through integration with Devart security components.

Advanced Dataset and Query Components

Provides components for executing queries, managing datasets, running database scripts, and retrieving database metadata.

High-Performance Data Operations

Implements optimized data access algorithms, connection management, and efficient data retrieval methods for responsive database applications.

Flexible Data Type Mapping

UniDAC includes mechanisms for mapping database specific data types to application level data types. This allows developers to handle differences between database systems while maintaining consistent dataset structures within applications.

Connection Pooling

UniDAC supports connection pooling to reuse established database connections across application operations. By maintaining a pool of active connections, applications can reduce connection overhead and improve performance in environments with frequent database access.
