Course Description

Introduces the design, uses, and terminology of a database management system. Includes data modeling using Entity Relationship modeling tools, normalization rules, relational database terminology, and program/query development. Audit available.

Intended Outcomes for the course

On 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

Direct instruction (+ study time) in discipline-related computations 

  • Interpreting business logic as a collection of Entities, Attributes, and Relationships between those Entities.
  • Identifying functional dependencies between Attributes of an Entity.
  • Applying the rules for key selection to identify candidate keys, primary keys, foreign keys, composite keys, and surrogate keys.
  • Determining the minimum and maximum cardinalities between Entities in a Relationship.
  • Explicitly tracking assumptions made during the process of creating Entities, Relationships, and cardinalities.
  • Resolving ternary and greater Relationships through the introduction of Intersection Entities.
