Oracle Database 12c: Introduction to SQL

ABOUT THE PROGRAM

Since the early days of computers, there was always a need to store data. First, it was stored just in the computer’s RAM and later on in flat files. As the need for more data grew, newer options came into the market. Dbase was the forerunner among such technologies. It was followed by Foxbase, FoxPro etc. To suit to the Windows environment these DBMS systems either upgraded with Windows versions or there were new players in the market such as Microsoft Access. Data still kept pouring in and the need to handle such large amounts of data gave rise to the RDBMS and ORDBMS packages that we are all familiar with now. A starter among them was ORACLE. Oracle used single statements to retrieve, update or delete data from the database as compared to the programs a user would have to write for doing the same job early on.

PROGRAM OVERVIEW

Oracle, since its inception as a Database, has had many versions namely Oracle 1 through Oracle 8, then 8i, 9i, 10g, 11g and the latest being 12c. Each of these versions come with three main components i.e. SQL* PLUS, Oracle Forms and Oracle Reports. Oracle also comes in various Database Editions such as

  • Oracle Enterprise Edition
  • Oracle Standard Edition
  • Oracle Standard Edition One
  • Oracle Personal Edition
  • Oracle Express Edition

However, the most primary component of the database in all these versions has been SQL*Plus. SQL*Plus is the application that uses a query language to perform operations such as insert, update, delete and others.

The Oracle Database 12c: Introduction to SQL, helps the delegates to write multiple queries which can also be executed as a single query using the operators provided by Oracle SQL. The Oracle SQL allows its users to store data using DDL operations, manipulate data with DML operations and control data using DCL. It also provides for Transaction Control using the TCL feature. During this course, the delegates learn to manage objects within a schema, work with different types of views, manage roles and privileges, work with external tables etc.
