Use Case: Managing Enterprise-level Diagrams

With all your harvested models and metadata, ER360 allows you to construct and visualize Enterprise Architecture (EA) diagrams — helping data modelers, architects, and business users understand the relationships and data flows across systems.

This is particularly useful during modernization, mergers, or platform transitions — for example, when moving from a legacy DVD rental business to an OTT streaming platform.

Example: eMovies Transition to OTT Platform

In this example, we track and visualize the evolution of three key systems:

• DVD Rental System

  Legacy system with tables like CUSTOMERS, MOVIES, and RENTALS.

• OTT Streaming Platform

  Modern system with USERS, CONTENT, and STREAMING_HISTORY.

• Enterprise Data Warehouse (EDW)

  Central integration layer with DW_CUSTOMERS, DW_CONTENT, and DW_USAGE_FACT.

To create and view EA diagrams:

1. Go to the Application Menu > EA
   The Enterprise Architecture page opens.

2. Select the models you want to connect (e.g., DVD, OTT, EDW).

3. Use drag-and-drop to position models and draw relationships.

4. You can define connections/links such as:

   • DvDRental -> OTT

   • DataWareHouse -> OTT

   • DataWareHouse -> DvDRental

You can also see the Model properties in the right-hand column properties pane:
