Entity Relationship Diagram
An entity relationship diagram (ERD) represents the sets of the data objects with entities,
attributes and relationship between them. The following diagram has been mapped to support the
computer application of the athletic meets for the school. The relation has been represented using
Chen’s notation of one to one, one to many and many to many (Łacheciński, 2013). Based on
this ERD model the further schema can be developed and implemented in the application
development.
