Construct a reasonable ERD to capture the data requirements. List the entities, relationships with multiplicities, and attributes. Specify the primary key of an entity whenever possible. Note that you should use the Crow's Foot notation as supported by ER Assistant v2.1. ER Assistant supports attributes for relationships and your ERD may have relationship attributes.
Simple Team Modeling Tool (TMT) Prototype
Modelers from a consortium of multiple organizations can work on developing
multiple Software and Engineering models. TMT provides some very simplistic
supports.
A model has a unique model Id, a name, an optional description, and a start date.
This can be regarded as the description of the model.
A model is composed of one or more top-level components. A component has a id, name and an optional description. A component has a predefined type, e.g.
'Conceptual', 'Mongo_Logical', MySQL_Logical', etc. A component may have subcomponents. The actual component content may be an ER model, UML model, SysML model, etc. A component may have some relationships with other components, and the descriptions of these relationships should be stored.
