Object-Oriented Database Management Systems provides a critical review and technology assessment of Object-Oriented Database Management Systems (OODBMS). This report can be used to understand OODBMS technology and the current state of commercial OODBMS. This report can be used as the first step in an evaluation aimed at selecting an OODBMS for use in a given application development effort. This report describes a broad range of OODBMS evaluation criteria. It then evaluates five commercial OODBMS products on a subset of the overall criteria. An appendix to this report defines a template, useful as a guide for performing an evaluation of OODBMS.
A State of the Art Review of Software Design Methods provides an analysis of software design methods. Software design is an extensive topic with a rich history. This report provides readers with a useful snapshot of software design technology. It can be used as a tutorial for the uninitiated, a starting point for detailed research, or a guide for those developing software in the future. The report includes coverage of the nature of design, its evolution, its status, and directions for the future. New paradigms for software development and programming are presented, with a discussion of the role design plays in each. Specific design technologies are presented. The report concludes with the authors' perceptions of the state of the art of software design. Object-Oriented technology and its influences on software design are covered because this technology promises to have a large impact on future software development.
The report, A Review of Non-Ada to Ada Conversion, provides a discussion of the processes and problems involved with the conversion of software from early High Order Languages (HOLs) to Ada. Specific compatibility and format difficulties are discussed for each HOL examined, including C, Cobol, Fortran, Jovial, Modula-2, and Pascal. Several conversion approaches are presented, along with the advantages and disadvantages of each approach. Three specific conversion projects are summarized. Points of contacts for several currently available Commercial Off the Shelf (COTS) tools to help the conversion are included for reference, with a short discussion of each tool.
Each of these three reports is available for $30 from the Data & Analysis Center for Software (DACS). Contact the DACS Newsletter Editor ([email protected]) for more information or go to the DACS Store.
