Abstract: Structures have always been employed in designing software applications. In order to specify separate data structures, however, classes should be introduced to facilitate the process. The development of databases, in this case is made easier to specify records, data items, and simpler to identify unique keys within the database. The dataflow and entity relationships diagrams help in the development process. This paper provides a simple set of diagrams emphasizing the importance of these relationships.

Keywords: dataflow diagram DFD: the design of the flow of data and records prior to programming; entity relationships diagram ERD: the diagramming design that identifies and specifies the type and category of association; classes: an object or entity types; data structure: a set of related data objects or records (search for similar items in EconPapers)
