Abstract : This paper considers the problem of maintaining large files describing complex and widespread operations in a computer as well as storing and retrieving the necessary information in real time. The requirements are first stated generally, in terms of the hierarchy of the organization, hierarchy of the computers used, the language of communication with the file and the retrieval and updating. The paper then turns to a more detailed description of specific features and techniques. Three types of files are considered: Resources File, Plans File, and a Technical Library File. The organization of each file, use of trees and lists and loading of files are described. Techniques are given for retrieval by position in an organizational hierarchy, cross referencing between files, and the creation of a thesaurus and a classification system. (Author)
