This section contains documentation for features that provide external access to Reality, including web features. It is divided into seven subsections:
RealWeb. This feature provides the Web developer with access to data held in a Reality database, by making it possible to call a DataBasic subroutine directly from a Web browser by simply specifying a URL. Subroutines that will be called from RealWeb must be specially written using the supplied DataBasic API - this allows the programmer to fetch arguments passed to RealWeb, and to construct an HTML page that is returned for display in the browser.
The RealWeb section describes the DataBasic subroutines supplied with RealWeb and how to use these to construct HTML pages.
Reality Java Interface. This section provides advice for the Java programmer wishing to enquire upon or update a Reality database via one of the following methods:
This section contains Acrobat versions of manuals that do not form part of the main documentation, but that you may need or find useful.
