Kurs informasjon: Accessing the DB2 UDB for System i Database Using SQL

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 System i high-level languages as an alternate means to access the database.

This course is designed to teach System i programmers and highly skilled System i users how to access the DB2 UDB database using the SQL. Students will learn how to create, maintain, and query the database using the interactive SQL interface and iSeries Navigator.
