Kurs informasjon: IBM i DB2 and SQL School

SQL is a very powerful programming and database language that is widely used in business today. For example, SQL can be used to perform interactive database queries as well as to extract data from a server and pass that data to a Java applet running on a client PC. SQL is frequently used in i system high-level languages as an alternate means to access the database.

This course is designed to teach i programmers and highly skilled i system users how to access the database using SQL. Students will learn how to create, maintain, and query the database using the interactive SQL interface and System i Navigator.

This course provides lectures and hands on labs in a face-to-face classroom setting. This course is also offered in a live virtual classroom environment (ILO - Instructor Led Online) with hands-on labs: IBM i DB2 and SQL School - ILO (OV470NO).
