Importance of Data Flow Diagrams and Entity Relationships Diagrams to Data Structures Systems Design in C++ “A Practical Example”

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.
