2Week 4 Assignment – E-R DiagramsAn entity relationship diagram, also referred to as ER diagrams or ERD, shows the relationships of entity sets stored in a database. This means an ERD is a structural diagram utilized to design data bases. It offers an inclusive view of the information system and becomes the blueprint for producing the physical data structures [ CITATION Til20 \l 1033 ]. An ER diagram demonstrates the logical structure of databases by describing the entities, their characteristics, and illustrating the connections among them [ CITATION Sik11 \l 1033 ].My development idea for a computer-based tool to assist a system analyst would be a case tool, like the one displayed on lucidchart.com website.
