Abstract : A Data Description Language (DDL) for describing the organizations of data in files and data bases, is specified. This language has been developed as part of a utility which will process data bases or data files, with existing formats and organizations, and which will produce these data in new desired forms. The DDL is sufficiently rich and expressive to be readily used to describe the organization of existing data bases, the structure of desired data bases and the transformations between the existing ones to the desired ones. The DDL is specified in the form of an extensive manual containing specifications and a set of detailed examples of the use of the DDL. (Author)
