Duration: 2 days

 
 

Relational Databases & Data Modelling Overview Course Overview

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. 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.

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.

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.

Skills Gained

The delegate will learn and acquire skills as follows:

  • The database approach
  • Database Management Systems
  • The logic of database architectures
  • Entity modelling
  • Constraints and assumptions
  • Data normalisation to the third normal form
  • Logical data structures
  • The relational schema
  • Database constraints
  • The concept of views
  • De-normalisation techniques
  • An introduction to simple queries in Structured Query Language (SQL)

Course Reviews

Excellent course, extensive reference literature and well described and explained throughout. Workshops and problems were good and very relevant to the material and really helped to drive home points made in the course. Was very happy with the training centre and facilities. Instructor was excellent, friendly, knowledgeable and happy to answer questions to fill in and extend the material.

Daniel - Analyst Programmer - Insurance


Definitely recommend this to any colleagues starting out on Data Analysis.

Dan - DATA ANALYST - Utilities


The instructor taught the group very well, he got each attendee involved and made sure everyone was understanding each part. Would highly recommend.

Mark - Manufacturing


Great course, led in a very professional manner. Would definitely consider further courses at Stay Ahead Training.

Imran - Data Analyst - Retail / Hire


Found the course to be very useful and have taken some key points away from the course which will enable my work to be more streamlined.
