| Abstract: | Much of transaction processing involves classification, that is, the
categorization of inputs into outputs based on various tests. In
Artificial Intelligence (Al), classification systems are generally
represented in terms of AND/OR graphs. Such graphs are collections of
production rules that capture declaratively the logic of an application
domain. If one views a transaction processing system as a classification
system, it becomes natural to represent it in terms of an AND/OR graph.
In this paper, we present an interpretation of dataflow diagrams used in
Structured Analysis as AND/OR graphs. By examining the dataflow
diagrams, production rules capturing application-specific knowledge can
be constructed. This interpretation has two implications: 1) production
rules can be used to unify analysis and design since the same data
structure (the rule) is used for both purposes, and 2) the resulting
design can be simulated for purposes of explanation and what-if
analysis. We also discuss some of the general pros and cons of
production systems as they pertain to systems analysis and design. |
