         This newsletter is to introduce DSAC's Ada task group and to give 
    a bit of our history.  Established in December of 1986 as the Ada
    Language Project, we were to assess the applicability of Ada to the
    development of the Defense Logistics Agency's business processing 
    systems. After designing and developing our first application, the Ada
    group made several conclusions, including:
    
         1) Add Ada as a DLA software programming language.
    
         2) Maintain Ada expertise by training personnel and beginning a
    software engineering user's group.
    
         3) Utilize Ada to create software for functions that commercial
    packages have not addressed.
    
         4) Develop/obtain a library of reusable tools, a reusable
    software library manager, and Ada/DBMS(s) interface(s).
    
         5) Because Ada allows arithmetic precision to vary from one
    machine to the next, the organization's money handling needs require 
    that modules be written/obtained that would provide the necessary
    accuracy and precision.
    
         6) Once this precision is achieved and Ada DBMS support is in
    place, the agency may consider using Ada for applications that may
    benefit from Ada's strengths. It is important that an APSE be 
    sophisticated enough that it can help not only the analyst and
    programmers to design and code, but also the project managers to
    devise project schedules, control resources and monitor the progress
    of development through the application's entire life cycle.
    
    
         At present, the group is involved in a project which utilizes
    Ada in an information management system that is ultimately aimed for
    an OSI environment.  Called the Logistics Information Exchange (LINX),
    this project is to design a standard, portable interface between user
    applications and the commercial service level facilities residing in
    the top layer of the OSI model.
    
         We'll be glad to hear from anyone who has any questions or
    comments. We would also like to know how any military agencies are
    using Ada, and if anyone is working on the application layer of the
    OSI model.
