There are three parts to implement.
Part 1
Draw the Entity-Relationship Diagram (ERD) of the operational data stored in the third normal form and convert the ERD to a relational schema. Describe any design assumptions made. Implement the relational schema with an SQL script file. Insert sufficient example data for thirty students, nine courses (three for each trimester for trimesters 1, 2, and 3 ), and six lecturers.
Part 2
Draw the ERD of the data warehouse and convert the ERD to a relational schema. Implement the data warehouse with an SQL script file. Implement an ETL scheme with one or multiple SQL script files, one script file for each trimester, to extract data from the operational data store and load them into the data warehouse. If needed, create and drop temp tables during the ETL process. An ETL operation is to be run every trimester.
Part 3
