Relational databases often drive the company-critical and web-enabled applications essential for achieving success in a highly competitive market. This training course is designed to deliver the groundwork for building and working with relational databases — including Oracle, SQL Server, and MySQL — and enabling you to develop and use relational databases in your environment.

You Will Learn How To

  • Design, build, and use a relational database using proven methods
  • Ensure database designs accurately model business requirements
  • Normalise and denormalise your data to optimise performance
  • Work with integrity constraints
  • Automatically generate database documentation using CASE tools

Important Course Information

Software:

  • Oracle's free SQL*Developer Data Modeler is used to design and generate a database
  • PostgreSQL RDBMS along with the SQL Workbench/J IDE are used for database demonstrations and samples
  • Concepts apply to any relational database environment
