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 Plymouth

Plymouth is a port city in Devon that also goes by the name of the Ocean City of Britain. The city is known for its narrow cobbled streets and a maritime heritage. Plymouth lies between the mouths of the two rivers  - Plym and Tamar – and hence its name. The first settlers had come to Plymouth in the Bronze Age. It was in 1620 that the Pilgrim Fathers departed from Plymouth in search of some New World. They established a new colony at the time known as the Plymouth Colony and later as The United States of America.

Plymouth grew during the Industrial Revolution as a Commercial Shipping Port. Imports and passengers both poured into Plymouth from the Americas. Plymouth was also using its ports to export minerals such as time, lime, china clay, copper and arsenic. In 1928 Plymouth achieved a city status when three of its neighbours also joined together under the same name. During the Second World War, Plymouth was a target for the Nazi forces as it sided with the Allied forces.

Governed locally by Plymouth City Council, the city is home to 264,200 people as per the data collected in 2016. The economy of Plymouth has for long been influenced by industries such as Ship-building and sea-faring, but since the 1990’s it is turning more towards the service-based industry. In the whole of Western Europe, Plymouth is home to the biggest Naval-base.

Plymouth 2020

In 2003, Plymouth Council started the "Vision for Plymouth" – a project for the development of the city of Plymouth.  The project aims to build shopping centres, an avenue as a part of the project and a cruise terminal. Another aim of the project is to increase the population to 300,000. 2004 saw the old Drake Circus being demolished and replaced by the Drake Circus Shopping Centre that opened in October 2006. In one of another project,  the Plymouth City Council's headquarters are to be shifted and the civic centre to be demolished. The demolished land of civic centre will be sold so as to generate revenue for building the new council headquarters.at the location where the Bretonside bus station is currently located. The Plymouth Pavillion arena is also up for demolition in one of the projects. This would be replaced by a new canal links from Millbay to the city centre.
