How would you change the current design and how does your new design address the problems you have identified with the current design.
Calculate a canonical cover for above set of functional dependencies (show each step of your derivation with an explanation).
What rules would have to be enforced based on entity type? Choose one entity type and discuss what enforcement is needed by the database or application.
Structured Methodologies, Data Flow Diagrams, Entity Relationship diagrams, Structured English, Decision Tables and Cohesion/coupling.
When increasing cardinalities from 1:N to N:M, which of the given steps are included in process the order of steps listed below is not relevant, only steps themselves?

Transform the tables into one or more tables in BCNF. Write the primary keys, candidate keys, and referential integrity constraints.
Describe all the tables - get table_name, status, num_rows, user_stats in user_tables system vie
Creation of a data classification scheme. A discussion about the sensitivity and mapping of the data into the data classification scheme
