Software Composition with Extended Entity-Relationship Diagrams

Abstract
We introduce a compositional approach to application software
construction. In our approach, an extended entity-relationship
diagram (EERD), which represents the component types and the
relationship types within an application domain, is used as a template
of executable programs in that application domain. As we use
structural active objects as the components of a program, we can
obtain an executable program simply by connecting them as dictated by
an EERD. Furthermore, the graphical editor in the proposed software
development environment uses EERDs as menus in constructing an
application software. An EERD used as a menu can enforce legitimate
patterns of relationships among components besides that they provide
an intuitive view of available components and possible relationships
among them.
