Virtual Data Access Components (VirtualDAC) is a library of components that extends data processing capabilities in Delphi, C++Builder and Lazarus (FPC) on Windows, macOS, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. VirtualDAC consists of components that provides such capabilities as working with non-tabular data, performing SQL-queries to data in memory or to data from sources in different RDBMS’es etc., that are not available for standard data access components.
- TVirtualTable – Dataset that stores data in memory.
- TVirtualDataSet – Dataset that processes arbitrary non-tabular data.
- TVirtualQuery – Dataset that is used to retrieve data simultaneously from several different RDBMS’es.
