SQL is a query language standardized by the ANSI Institute, which is used to retrieve information and to edit database structures in to relational databases. Many reporting tools produce underlying SQL language automatically: to understand SQL Language is the basic requirement for developing Business Intelligence environments and producing better reporting.
During the training, you will learn the SQL language grammar, to help you do both simple and versatile relational database queries. Our training provides the basic skills for the reporting of data in the database query language, as well as a good basis for further study of information content editing (Data Manipulation Language), reporting software, database maintenance, and application development.
The training is primarily intended for database users and the reporter designers who have no previous experience in SQL queries. The course uses CGI Academy own-developed material. The material is based on SQL language standard, but it includes key differences in Microsoft and Oracle’s own syntax.
The training does not require prior database or programming experience.
