      Training objectives 

      The training is designed for anyone wishing to learn the technique of using relational databases. The skills acquired during the training can be useful in performing daily tasks in work of a programmer, database administrator and analyst creating various reports and statements.

      During the training the participants will gain knowledge on the construction of a relational database and the principles of using SQL language for data processing. Knowledge of the basics of SQL can be used to independently obtain and transform data from databases operated in the organization. This is a valuable competency for people who deal with the generation of various statements, reports and analyses on a daily basis. The examples of SQL language application discussed during the course come from the most common scenarios of data presentation and analysis.

      Skills

      After completing the course, the participant will be able to:

      • Create queries and work with objects contained in databases using the T-SQL language.
      • Properly design a database, choose the right data types to match the requirements of the database structure.
      • Create, modify and delete tables and data using T-SQL
      • Design aggregate and group queries, use subqueries.
