Relational Databases & Data Modelling Overview
Course Code: RDBO
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.
Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
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
Very Good two day course John our course instructor was very informative and give thorough information on relational databases and SQL query's. I enjoyed the breakout workshops which was very engaging to get involved with the exercises provided, overall very happy with the training thank you.
James - Government - November 2024
Very nice paced, allowed me to take everything in and I never felt like I fell behind. Practical tasks were great and break out rooms were interactive.
Jake - Trainee Software Developer - Utilities
We got through the course material at a reasonable pace. The instructor John was able to answer any and all questions I had and elaborated on more concepts that he felt were suitable to my level of training.
Keiron - Software developer - IT
Very good course, John was very helpful and approachable. All learning outcomes successfully achieved, which has given me greater confidence and knowledge within this particular subject.
Daniel - Commercial Officer - Environmental
The trainer John was very good at teaching the team about databases. He was very patient and understanding. He listened to all of our concerns and responded to our questions quickly.
