#### Product Description

Virtual Data Access Components (VirtualDAC) is a library of components that extends the functionality of processing data 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 allows you to perform tasks that are not available for standard data access components, such as working with non-tabular data, performing SQL-queries simultaneously to data in different RDBMS'es etc. VirtualDAC is designed to help programmers develop really lightweight, faster and cleaner applications.

#### Requirements

An application based on VirtualDAC does not require any additional files or client libraries. If the TVirtualQuery component is used in an application, the need for additional libraries depends on data-access components which are used as source datasets for TVirtualQuery.

#### Installation

Compiled versions of VirtualDAC are installed automatically by the VirtualDAC Installer for all supported IDEs. VirtualDAC Standard Edition with Source Code must be installed manually. For more information, see the Installation topic of the VirtualDAC Help documentation.

It is important to know that ODAC, SDAC, MyDAC, IBDAC, PgDAC, LiteDAC, UniDAC and VirtualDAC components use common base packages, so product compatibility is provided for the current build only. In other words, if you upgrade one of the installed products, it may conflict with older builds of the other products. In order to continue using the products simultaneously, you should upgrade all of them at the same time.

#### Documentation and informational resources

VirtualDAC comes with full documentation, which includes a detailed reference for all VirtualDAC components and classes, and a set of articles that highlight VirtualDAC advanced functionality. The VirtualDAC documentation is integrated into your IDE at the install time. It can be invoked from the VirtualDAC menu added to the Menu Bar, or by pressing F1 in an object inspector or on a selected code segment.

If you have a question regarding VirtualDAC, refer to the Getting Support topic in the VirtualDAC help for information on how to contact the VirtualDAC support team.
