Course Description
Intended Outcomes for the course
Upon completion of this course the student should be able to:
- Describe and explain the importance of database development, processing, and security.
- Design and prepare a data model using an Entity Relationship Diagram.
- Communicate effectively with database professionals using relational database terminology.
- Communicate effectively with database professionals regarding the rules of normalization.
- Prepare queries to a database using Structured Query Language.
Outcome Assessment Strategies
- Design and prepare a data model using an Entity-Relationship diagram and a Semantic Object Model diagram.
- Apply technology to create data designs using both the E-R model and the Semantic Object model.
- Data model should be a real business or personal database.
- Data model should include at least 5 and not more than 8 strong entities/objects.
- Data model should include 1:N and M:N relationships.
- Prepare queries to a database using Structured Query Language.
- Write queries using basic SQL including WHERE, built-in functions, subqueries, joins, LIKE, BETWEEN, EXISTS
- In satisfying the assessments, students must dmonstrate written communication skills. Other assessment choices include:
- Contextual written tasks in or outside of class.
- Written case study analysis.
- Individual or group projects.
- Class presentations.
- Quizzes and/or examinations.
- In class interactive role-plays
