Database Design Project
This week, you need to work on the Logical Modeling Design and to specify the entries, columns and their relationship. Use an entity-relationship ER diagram to visualize the database.
Your schema should include some attributes that make it possible to include some transactions that involve aggregate functions. For example, a school schema would allow for queries to calculate enrollment in each section of the average enrollment in courses for a given department, or the total courses being taught by each instructor, etc. This should also make interesting constraints and triggers possible. Review this basic example of a requirements document and Conceptual Data Model.
Turn your ER diagram into a normalized relational database design for the (subset of the) domain (i.e. a set of tables, each with appropriate attributes, a primary key, and appropriate foreign keys. The database should be based on the ER diagram, but one-to-one and one-to-many relationships may be implemented by appropriate attributes in the “one” entity, rather than as separate tables. You relational database must be at least in 3NF. Remember to determine the cardinality of the relationships. You may want to decide on cardinality when you are creating an Entityrelationship diagram ERD relationship table.
Please find the ERD in the file and give the 1NF,2NF and 3NF of the table
