The Codd and Date Premise Given all of the above characteristics of a good data warehouse data model, we submit that the best data-modeling technique you can use is one based on the original relational database design-the entity-relationship diagram (ERD) developed by Chris Date and Ted Codd.
For example, flowcharts for evaluating information and internal control systems; process maps, like the one shown in exhibit 1, for showing a pictorial diagram of a business's activities and processes; data flow diagrams for designing information systems; entity-relationship diagrams for use in modeling and depicting database designs.
0, an affordable, powerful tool for database modeling and design using entity-relationship diagrams (ERDs).
