5. Entities

Entities are the main focus of your development in the Logical Modeler. They are the starting point for most model development.

An entity can be anything that a user works with in their business. For example, in an order entry application, a Product, a Customer or an Order may be an entity.

For each entity, you can:

• define elements,

• define relationships to other entities,

• add notes,

• build the entity, and

• review build error messages.

Each entity must be assigned a type. This is very important in determining how entities interact with each other via relationships, and how they are implemented in the repository when the model is built.
