Relational Database
Design
The goal of this seminar is to develop sound principles for determining the
value of information, what data should he stored, how it should he
organized, retrieved and managed to provide a manageably sized,
responsive, user-friendly, accurate, information-producing relational
database.
Objectives: By the end of the course, qualified and diligent participants
should know:
The concepts of data and information and how data produces
information
The identification procedure for entities and the procedure for
determining their interrelationships
How to construct logical data structures for modeling data
How to construct a relational database starting from a logical data
structure
How to construct a relational database starting from an existing
collection of data or existing “tables.”
During the seminar, participants will be given opportunity to:
Identify attributes, entities, values, and relationships
Use relational operators on a set of tables to produce information
Normalize an existing set of data into a set of well-formed relations
Construct a logical data structure
Map a logical data structure into a set of well-formed relations
