Data Modeling and Database Design
Final Exam
Course Introduction
This course provides an in-depth exploration of the principles and practices involved in data modeling and database design. Students will learn how to analyze data requirements, develop conceptual, logical, and physical data models, and apply normalization techniques to ensure data integrity and efficiency. The course covers relational database theory, entity-relationship diagrams, SQL implementation, and schema optimization strategies. Practical assignments and projects will give students hands-on experience in designing robust database systems to support real-world applications, preparing them for roles in database administration, software development, and data management.

Sample Questions
Q1) Compare and contrast subqueries and joins.
Answer: Subqueries and joins are both used to process data for queries that require data from multiple tables.Subqueries involve embedding a second query within the WHERE clause of the first query.Many levels of subqueries can exist.Joins involve combining the rows of multiple tables into a single relation whose rows contain the data from all the tables that are joined.This new relation can then be processed by the other clauses of the SELECT query.One notable issue with subqueries is that only data from a single table may appear in the result that is returned by the query.One notable issue with joins is that any unmatched rows in either table will not appear in the result that is returned by the query.
Q2) Which of the following is not a standard data type used in SQL?
