Importance of ERDs in Database Design
While diagrams have played a critical role in software development, engineers often find the manual drawing of such diagrams a laborious and time-consuming task. However, the use of Entity-Relationship Diagrams (ERDs) does the heavy-lifting in database design and software development (Habib, 2019). Through Entity-Relationship Modeling (ERM), developers can describe information based on attributes, entities, and relationships to facilitate the process of database design. ER models are widely used in controlling and monitoring databases in a system. When using models, data is treated as entities comprising attributes and their corresponding relationships. In ER modeling, developers make a comprehensive graphical representation of the entities and relationship types using ERDs based on robust mathematical foundations of concepts such as logic, lattice theory, set theory, modern algebra, and mathematical relations (Habib, 2019). Even in small databases, process or system documentatio...
