Simple Team Modeling Tool (TMT) Prototype Modelers from a consortium of multiple organizations can work on developingmultiple Software and Engineering models. TMT provides some very simplisticsupports. 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. Construct a reasonable ERD to capture the data requirements.List the entities, relationships with multiplicities, and attributes. Specify the primarykey of an entity whenever possible. Note that you should use the…
