    The Optical File Cabinet (OFC) is patterned after a conventional office file cabinet where all versions of a stored item are retained, but the current version of each item is the easiest to find. The OFC retains the favorable aspects of write-once optical disks while preserving the existing relationship between the operating system and the file system. Alternate approaches to write-once storage an... View full abstract»

    The author proposes that the formality of specifications and designs be developed together in box structures with many sponsor and user interfaces. Box structures of data abstractions allow the stepwise refinement and verification of hierarchical system designs from their specifications at formal and informal levels. He discusses the features and advantages of the approach. He used a navigation an... View full abstract»

    The authors identify problems with present parallel processing systems, and present Armstrong, a hardware-software system that is designed to address some of the problems discussed. They briefly describe the Armstrong hardware and discuss, in depth, the operating system software, and performance of the system on a real application, namely, and computation of the 2-D discrete Fourier transform of a...

    An overview is given of past present data-modeling trends, and future directions are identified. The three traditional and commonly used data models that gained wide acceptance in the late 1960s and early 1970s and are used extensively today, namely the relational, hierarchical, and network models, are reviewed. Semantic data models that attempt to enhance the representation of operational informa... View full abstract»

    Programming techniques necessary for high performance on the 3090 Vector Facilities are illustrated, showing that VS Fortran programs can achieve near-maximum execution rates. Relevant features of the 3090 architecture are reviewed, stressing the need to make efficient use of a hierarchical storage system and take advantage of the compound vector instructions. The key programming techniques for ma... View full abstract»

    Two products that transform mathematical expressions into useful results are reviewed. One is Math View Professional version 0.94, a self-contained mathematics application that is capable of performing a nearly encyclopedic range of mathematical, graphical, and statistical operations. The authors briefly summarize the program's features, touch on the manual supplied with the review copy, offer som... View full abstract»
