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 Portsmouth

Portsmouth,  situated on the Portsea Island,70-miles south-west of London, in Hampshire is home to 205,400 people. Portsmouth is said to have been existing during the Roman civilization too. Portsmouth for many centuries has served the Royal Navy as well. During the French invasion of 1545, Portsmouth is said to have served England as a line of defence. It is also known as the oldest dry dock of the world.

Portsmouth became the first to go into mass production. As such it also came to be known for being an industrialized city. The Portsmouth Blitz, during the Second World War, claimed 930 lives, as a result of bombing by the Nazi forces. The troops deployed to liberate the Falkland Islands in 1982 were from the Portsmouth’s naval base. When Hong Kong, the last British colony, was to be transferred, The Queen’s yacht Britannia left to Hongkong from Portsmouth.

Literature

‘Pompey’, a novel by Jonathan Meades, shows Portsmouth as the home of many criminals.Fanny Park, the lead character, in Jane Austen's novel Mansfield Park, is a resident of Portsmouth. Incidentally, many of Jane Austen’s made sure that her novels came to end in the Portsmouth city. In his novel, ‘The Life and Adventures of Nicholas Nickleby', Charles Dickens has portrayed Nicholas and Smike getting involved in a theatrical troupe in Portsmouth. The Aubrey-Martin series by Patrick O’Brian mostly saw Captain Jack Aubrey’s ships sailing from Portsmouth.

Many crime novels such D.I. Faraday/D.C. Winter novels by Graham Hurley and the Heartsone by C.J.Samson were set in Portsmouth.Published in 2014, the ‘Portsmouth Fairy Tales for Grown Ups’, had locations in its stories that were from around Portsmouth.

The Fratton Park is the home ground for Portsmouth F.C. The team has been victorious twice winning the Football League titles in 1949 and 1950. The team was victorious in the FA Cup in 1939 and 2008. The team once again started playing the Premier League in the 2003 season. 2010 to 2012 was a period of great difficulties for the team. They went down to the Championship level and then to LeagueOne by 2012. 2013 saw them further relegated to the fourth tier of the English Football, the League Two. Pompey Supporters Trust, in April 2013, purchased the team and made it making it the biggest fan-owned football club in the history of English Football.
