Relational Database Design

Course Description

This course is one common starting point for the entire database curriculum. The objective of this course is to consider the logical design of relational databases using a methodology known as semantic data modeling and related practical techniques. Major subject areas to be explored are: • Building a logical data model of increasing complexity and accuracy • Transforming a logical model into a physical model for a relational database • Using object oriented and semantic modeling techniques to refine a model • Identifying classic structures and patterns which may be reused among many different models. • Learn about star schemas, snowflake schemas and data warehouse models • Introduce the use of a data model diagramming tool and CASE tools • Consider the physical objects of a relational database and how they implement a logical model.
