Creating a Data Model (I.E)
An I.E data model shows entity-types as square cornered boxes (an entity is any person or thing about which data is stored.) The entity types are associated with one another; for example, a "Product" entity is purchased by a "Customer" entity. Lines linking the boxes show these associations. The lines have cardinality (multiplicity) indicators.
To create a data model:
1. In HOPEX, click the Logical data navigation pane.
2. In the navigation pane, click All data models.
3. In the edit area, click New.
The data model mapping creation dialog box opens.
4. Enter the name of the model.
5. Click OK.
The data model appears in the list of data models.
Data Diagram (I.E.)
A data diagram is a graphical representation of a model or of part of a model. The creation of a diagram varies slightly depending on whether you are in Windows Front-End or Web Front-End.
To create a data diagram:
Right-click the data model and select New > Data Diagram (I.E).The data diagram opens.
