Course Overview

A company’s success hinges on responsible, accurate database management. Organizations rely on highly available data to complete all sorts of tasks, from creating marketing reports and invoicing customers to setting financial goals. Data professionals like analysts, developers and architects are tasked with creating, optimizing, managing and analyzing data from databases – with little room for error. When databases aren’t built or maintained correctly, it’s easy to mishandle or lose valuable data. Our SQL Programming and Database Training Series provides students with the skills they require to develop, analyze and maintain data and in correctly structured,  modern and secure databases. A full presentation of the basics of relational databases and their use are also covered.

NOTE: This course provides a complete, hands-on introduction to SQL including the use of both SQL Developer and SQL*Plus, however Oracle tooling is not the focus of the course, and other tooling or database options may be available. Please advise if you want to use another tool in class and we can coordinate on options with you in advance of the delivery.
