Abstract

The ADL system provides a way in which computer programs written in different programming languages can share data. The ADL system comprises the ADL language and the facilities necessary to perform the data sharing function. The ADL language uses the concept of a data description and conversion module. A data description and conversion module, or more simply, an ADL module is composed of declarations and plans. Each declaration is an ADL description of how a particular program environment represents data. The plan portion of the ADL module contains ADL statements that instruct the computer system to convert the data representations of the source program environment into the data representations of the target program environment.
