Oracle Database 12c: SQL II – Intermediate

Overview

This course builds upon the prerequisite introductory volume from the Oracle Database 12c: SQL Expert Series and considers intermediate-level SQL topics such as writing database queries using the SQL-99 syntax and exploiting the power of built-in functions that extend the capabilities of SQL. 

You will learn how to complete an application schema definition by creating database objects such as relational views, sequences, synonyms, indexes, and others to complement the table definitions. The crucial topic of data integrity and how this is protected using declarative constraints are covered. 

With this course, you will also leave the idyllic realm of the learning environment and begin to explore such practical real-world considerations as database object security and database performance.
