SQL Server Data Access Components
SQL Server Data Access Components (SDAC) 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. SDAC-based applications connect to SQL Server directly through OLE DB, which is a native SQL Server interface. SDAC is designed to help programmers develop faster and cleaner SQL Server database applications.
SDAC, a high-performance and feature-rich SQL Server connectivity solution, is a complete replacement for standard SQL Server connectivity solutions and presents an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to SQL Server.
Native Connectivity to SQL Server
SDAC-based DB applications are easy to deploy, do not require installation of other data provider layers (such as BDE and ODBC), and that's why they can work faster than the ones based on standard Delphi data connectivity solutions. Moreover, SDAC provides working with SQL Server not only through OLE DB, but through SQL Native Client as well.

Wide Coverage of SQL Server Features
SDAC supports a wide range of SQL Server specific features, such as Transparent Application Failover, Notification, Queing and reliable messaging, SQL Server Compact Edition, User-defined Types (including HierarchyID, Geography, Geometry), Table-Valued Parameters, Filestream, and others.

Cross-Platform Development in Delphi, C++Builder, and Lazarus
SDAC is a cross-platform solution for developing applications using various IDEs: RAD Studio, Delphi, C++Builder, Lazarus (and FPC) on Windows, macOS, Linux, iOS, Android, and FreeBSD for both x86 and x64 platforms. SDAC also provides support for the FireMonkey application development platform, which allows you to develop visually spectacular high-performance desktop and mobile native applications.

High Development Productivity with SDAC
We provide various GUI tools that will increase your productivity: dbMonitor allows monitoring activity of your DB applications, Dataset Manager simplifies DataSet and DB controls tweaking, and others.
