The Relational Databases & Data Modelling Overview course is designed to give delegates practical experience in data modelling using entity relationship diagrams & data normalisation,also in designing relational databases using the normalised entity model.

Course overview:
Both entity modelling and data normalisation form core elements of this course. Delegates are not expected to have any prior knowledge of systems analysis or databases,and the course includes a brief introduction to the principles of systems analysis. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Course objectives:
Course Objectives The Relational Databases & Data Modelling Overview course provides an understanding of the structure of a RDBMS (Relational Database Management System) and the underlying principles of relational analysis and data modelling.

COURSE PREREQUISITES:
Requirements An understanding of Information Technology concepts and computer terms is required.

Target audience:
Who will the Course Benefit? Developers moving into the area of relational databases who need an understanding of the principles and logic of the relational database; programmers who are to start programming in SQL and need to know the principles on which it is built; programmers who need to understand entity modelling and normalization; analysts needing a knowledge of entity modelling and entity relationship diagrams and any others who need to know the principles of relational analysis and data modelling but do not need a complete systems analysis course.
