More about this course

This course has been running at JBI Training since 1995 and "hits the spot" every time. It enables people with little or no database knowledge to understand how databases are constructed, and how to query and extract the data stored in them using SQL language. You also learn to present this data in meaningful reports.

To facilitate learning, a subject matter expert leads the training, hands-on labs and discussions to ensure course topics are covered in a meaningful, relevant and timely manner.

Delegates may bring their own practical requirements and work to the course if the subjects and course topics are suitable.
