SQL Server Data Access Components (SDAC) by Devart is a library of components that provides native connectivity to SQL Server from Delphi and C++Builder, including Community Edition, as well as Lazarus (and Free Pascal) for Windows, Linux, macOS, iOS, and Android for both 32-bit and 64-bit platforms.

• Native Connectivity to SQL Server: SDAC-based applications connect to SQL Server directly through OLE DB, eliminating the need for additional data provider layers such as BDE or ODBC. This direct connection enhances performance and simplifies deployment.
• Cross-Platform Development: SDAC supports development across various platforms, including Windows, macOS, Linux, iOS, and Android. It is compatible with IDEs like RAD Studio, Delphi, C++Builder, and Lazarus, enabling the creation of high-performance desktop and mobile applications.
• Wide Coverage of SQL Server Features: SDAC offers support for a broad range of SQL Server-specific features, including Transparent Application Failover, Notification, Queuing and reliable messaging, SQL Server Compact Edition, User-defined Types (such as HierarchyID, Geography, Geometry), Table-Valued Parameters, and Filestream.
• Direct Mode: Allows applications to connect to SQL Server directly via TCP/IP without involving the SQL Server Client, significantly facilitating deployment and configuration.
• High Performance: SDAC is designed with optimized code and advanced data access algorithms to ensure high-performance data access, including fast controlled fetch of large data blocks and optimized string data storing.
• IDE Compatibility: Compatible with the latest IDE versions and editions, including Community Edition: Embarcadero RAD Studio 12 Athens, Delphi 12 Athens, C++Builder 12 Athens, and Lazarus (and FPC). It also supports previous IDE versions since Delphi 6 and C++Builder 6.
• Data Type Mapping: Provides a flexible Data Type Mapping engine, allowing custom correspondence between SQL Server and Delphi data types to suit specific application requirements.
• Monitoring: Includes the dbMonitor tool to monitor and analyze all database calls made by your application, offering per-component tracing of SQL statement execution, commits, rollbacks, and more.
• Support and Documentation: Offers comprehensive documentation, demo projects, and fast technical support from the SDAC development team, ensuring developers have the resources needed for successful implementation.
