Four steps are key to logical database modeling and design
1. Develop a logical data model for each known user interface (form and report) for the application, using normalization principles.
2. Combine normalized data requirements from all user interfaces into one consolidated logical database model; this step is called view integration.
3. Translate the conceptual E-R data model for the application, developed without explicit consideration of specific user interfaces, into normalized data requirements.
4. Compare the consolidated logical database design with the translated E-R model and produce, through view integration, one final logical database model for the application.
