This Relational Database Design training course delivers the groundwork for building and working with relational databases — including Oracle, SQL Server, and MySQL — and enables you to develop and use relational databases in your environment. You will learn to design your database to model your business requirements, normalise and denormalise data to optimise performance, and automatically generate database documentation using CASE tools. You will also learn how to simplify code and improve performance by avoiding common database design errors.
Relational Database Design Training Delivery Methods
Relational Database Design Training Information
In this training, you will learn how to do the following:
- Extract core business data requirements from source documents.
- Design both conceptual and logical data models using requirements.
- Recognise and accurately model complex data relationships.
- Apply data normalisation methods to refine data models.
- Physically deploy a relational schema from a logical model complete with tables, indexes, keys, and constraints.
Prerequisites
Before taking this course, you should already have basic knowledge and experience using a relational database and SQL.
