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.

ABOUT Crewe

Located within the borough of Cheshire East, 158 miles north of London, Crewe is a railway town of Cheshire, England. With a population of 72,863, Crewe is known for its large railway station. It is also known for Crewe Works – an organisation that used to manufacture and recondition locomotives. Crewe is also known as the birthplace of Rolls-Royce. Rolls-Royce remained in Crewe from 1946 to 2002 i.e. for a span of 56 years. Now it is the Bentley motor cars that are being manufactured in Crewe.

A mention of Creu is found in the Domesday Book - a record of the "Great Survey" of much of England & Wales that was completed in 1086 to determine the taxes that were owed to the King. However, it was not until 1843 that Crewe had its first modern settlement owing to a development in the railway system that had started in the early 1840’s. During the Second World War, Crewe became a target of the Nazi forces because of the railway junction as well as the presence of Rolls-Royce engineering works.

Developments

In 2008, the development of the current bus station and main shopping area were given up due to a shortage of funds. The railway station was also to be modified and as a part of the plan, it was to be moved to Basford. Anyhow, no such things happened and the current station underwent only some maintenance work instead. A new plan was developed by the Cheshire East Council. A Lifestyle Centre, furnished with swimming pool, a library and a gym was to be a part of the new plan. A new transport hub has been planned for Crewe that would be completed by 2027.
