Category: Databases and SQL

The course provides students with an overview of database theory and practical application. Students get to know SQL language and learn to create complex queries. They control database programmatically. The course provides students with skills and knowledge to use indexes and other optimisation techniques.

Standard course is run on PostreSQL system. For exclusive group the course can be run on any dedicated relational database system, for example Oracle, MS SQL Server, IBM DB2. Contact us for more info.

Notice:

  • For clients who want to learn just SQL language (for report and analytic goals) we recommend Course 'Access: Databases and SQL Laguage for Analysts’, which not include administrative, programming and performance issues.
    • For clients working on specific database platform and wanting to know exactly the SQL dialect used by that specific database, we recommend dedicated courses. Dedicated courses’ outline are practically the same, but we can show more specific details and tools, which every platform has.
