Abstract:

This report, an application of Parnas family methodology, describes the required user-visible behavior of a family of Military Message Systems MMS. These systems have two significant areas of commonality all enforce the rules described by the MMS security model and the user-visible data types and user commands required by each system can be extracted from a large set of data types and user commands. Based on a study of several existing message systems, this report defines the set of data types e.g., message, message file, directory and user commands associated with the MMS family. We use an Intermediate Command Language ICL to describe the user commands abstractly, i.e., to specify each commands effects without imposing unnecessary restrictions on either the command syntax or the physical characteristics of the users terminal. To simplify and shorten the specifications, we define a hierarchy data types. Also included is a glossary of terms. Keywords Requirements, Specifications, Security model, Program families, Functional specifications, and Message systems.
