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 Models are available with the following profiles:
• HOPEX Data Governance: Data Designer and Data Governance Functional Administrator
• HOPEX Data Architecture: Data Architect and Data Functional Administrator
