Db2 for z/OS: Introduction, Concepts & Facilities

This course introduces, describes and explains the fundamental principles of Db2 for z/OS. The course also explains the relational theory and concepts, and shows how Db2 adheres to them. The concepts of Db2 data storage, the Db2 system and its operation, Structured Query Language, the use of DB2 Interactive (DB2I), and the management of Db2 data using standard utility tasks are also introduced and explained. The course includes demonstrations and practical, hands-on exercises, and is relevant to all releases of Db2 for z/OS.

This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

What do I need?

  • webcam
  • headphones with microphone
  • sufficient bandwidth, at least 1.5 Mb/s in each direction.

What you will learn

On successful completion of this course you will be able to:

  • describe the relational concepts and theory, and the advantages of a RDBMS
  • describe the components of the Db2 system, their function, and how they are controlled
  • identify the objects used to store Db2 data and the relationships between them
  • code the SQL statements needed to create and modify Db2 data objects, and control access to them
  • code SQL statements to read and modify Db2 data and interrogate the Db2 catalog
  • describe and fully utilise all the functions available with DB2 Interactive (DB2I)
  • use online utilities to backup and restore data, and perform other data management tasks
  • describe the use of stand-alone utilities and identify situations where they may be required.

Who Should Attend

All IT professionals who need to understand and work with Db2 for z/OS.


A basic understanding of IT, with some exposure to database technology as a user. Whilst not essential, a knowledge of TSO/ISPF would be beneficial.
