Goals and Objectives of the Course

Students who complete the course will be able to:  
1. Discuss the role of database management systems in the enterprise.
2. Identify the basic constructs of a relational database.
3. Formulate and execute queries that answer specific questions using QBE, SQL, and QBD interfaces.
4. Demonstrate the ability to design simple database schemas that avoid data redundancy and employ correct data types.
5. Discuss the implications of poor database design.
6. Identify the ways in which data integrity and business rules are enforced in a database.
7. Generate basic tabular and form based reports based on data in a relational database.
8. Distinguish between transactional databases and data warehouses and between data warehousing, data mining, and decision support systems.
9. Give examples of situations where DSS and data mining tools should be used.
10. Describe how they would approach a data mining opportunity, set up the related tasks, and identify tradeoffs between different data mining techniques.
11. Discuss the differences and implications of those differences between enterprise level and personal databases.


Assessment Measures
