Abstract : Problems which have arisen in the management of data are examined for a common root. The examination suggests the need for better data description facilities. On this basis, an attempt is made to generalize the functions of data description, and a definition of a data description language is formulated. Current work on all aspects of these problems is surveyed and criticized on the basis of how well defined functions are fulfilled. Those problems on which no start has been made or for which only inadequate solutions have been proposed are summarized and a more comprehensive, generalized approach is proposed. Finally, the specification is given of a Data Description Language and its processor, which are being designed to meet the demands of the approach proposed and the problems discussed. (Author)
