The group assignment involves a 4 phase database design project for a center. Phase 1 involves choosing a center, writing a report on it, and identifying its database needs. Phase 2 is the conceptual design with an ER diagram and data dictionary. Phase 3 is the logical design with normalization of tables to 3NF and a relational schema. Phase 4 is the physical design with SQL scripts to create and populate tables, views for users, and 5 queries.
