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.
Data modelling with I.E is available with the following profiles:
• HOPEX Data Governance: Data Designer and Data Governance Functional Administrator
• HOPEX Data Architecture: Data Architect and Functional Data Administrator
Prerequisites
To use the I.E notation, you must select the corresponding option:
1. On the desktop, click Main Menu > Settings > Options.
2. In the options navigation tree, expand the HOPEX Solutions > Data folder.
3. Click Data Notation.
4. In the right-hand side of the window, select the I.E. notation.
5. Click OK.
Creating the Data Model
To create a data model in HOPEX Data Governance:
1. In HOPEX, click the Architecture > Data Models navigation pane.
2. In the edit area, click Hierarchy View.
*In HOPEX Data Architecture, click Data Models.
3. To the right of the Data Model Hierarchy folder, click the + New button.
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:
1. Move the mouse over the data model and click the Create a Diagram button on the right.
2. Select the Data Diagram (I.E) diagram type.
The diagram opens.
