    Data is a resource in both its physical and descriptive aspects. Both should be managed as any other major organizational resource—that is, data needs to be available on an organizationwide basis and thus requires centralized control. Described in this paper is a Data Dictionary/Directory (DDID) which provides such a method of centralized control over data management. View full abstract»

    A significant amount of work has been done in the area of general indexing in terms of simple indexing. This is reflected in the development of access methods such as VSAM. Very little work has been done on complex indexes. The only example given in this paper is the cascading indexes of CICS. Future work could include an expansion of the items discussed under complex indexes. In particular, some attention should be given to the relationships between different sets of data. A limited set of these relationships are provided by hierarchical data structures provided by systems such as the Information Managment System. View full abstract»

  • Functional structure of IBM virtual storage operating systems, Part I: Influences of dynamic address translation on operating system technology

    The operating system started as a means for controlling the sequential use of a computer more efficiently than a machine operator could do himself. As computers have grown larger, faster, and more able to support independent concurrent operations, operating systems have grown to provide for the simultaneous shared use of such systems. Thus multiprogramming, originally developed to make still more efficient use of the hardware, has become essential in its own right with the development of interactive computing. View full abstract»

    In designing a system like OS/VS2-2, which is aimed at meeting a broad variety of objectives in a multitude of complex operational environments, the tradeoffs and decisions are extremely difficult to decide. The intent of this paper has been to give insight into the thinking behind the major new elements of the OS/VS2-2 design. View full abstract»

  • Functional structure of IBM virtual storage operating systems, Part III: Architecture and design of DOS/VS

    DOS/VS represents a significant set of enhancements to the Disk Operating System. The addition of virtual storage support, additional partitions, and the relocating loader, among other items, extends the ability of the user to perform multiprogramming operations on System/370. Demands on the system operator are reduced, as are those on the scheduling function at the user installation. This type of operation, however, may require some changes in thinking by many DOS users, especially in considering factors that affect the total productivity of an entire computer installation.
