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 Chorley

A market town in England known for its cotton industry, Chorley is located around 20 miles North West of Manchester. In the 1970’s the town was home to a large number of factories which have now been demolished.  A few that remain from the said period are Morrison’s chimney and some mill buildings. Chorley finds the origin of its name in two Anglo-Saxon words ‘Ceori’ and ‘ley’ where the former stands for a person of some status and the latter refer to a place name.

Education

Chorley has a number of primary schools which are supported both by the council as well as the church. There are six high schools in Chorley as listed below:

  • Parklands High School
  • Michael's CE High School
  • Southlands High School
  • Albany Academy
  • Holy Cross Catholic High School
  • Bishop Rawstorne CE Academy

Some of the privately owned schools also run just outside the borough. Children also go to the Runshaw College for further studies which have expanded now into the administration site of ROF Chorley. Another college in Chorley is the Lancashire College that also offers adult education. The Lancashire College also provides exhaustive residential courses to its students. The Chorley Training College (also known as the College Day Training College since 1960) was another college for Chorley based students that functioned till 1981.

Media

There are two local newspapers that serve the citizens of Chorley - the weekly Chorley Guardian and the free Chorley Citizen. Chorley’s radio station, the Chorley FM, is a famous radio station having been cited in the  British comedy show on the television Phoenix Nights. The radio station got a full license to broadcast only in 2005. Earlier, the broadcasts took place for a few weeks.

A comedy series by Dave Spikey, Dead Man Weds, was based in Chorley. Most of the characters in Steve Pemberton’s The League of Gentlemen were taken from Adlington, located in Chorley.

Seal Films, which operates from Higher Wheelton, and is a film production company, was nominated for a short film in 2001 for a Royal Television Society Award.

Economy

The first industry that appeared in Chorley was mining.This can be seen today even as there is evidence of abandoned quarries today even in the outskirts of Chorley. The mining industry eventually gave way to the cotton mills.

The technology to manufacture trucks was borrowed from a neighbouring town, Leyland. Today even we can see trucks plying with the name Leyland imprinted on them in various parts of the world. During the Second World War, a large factory that was located on Pilling Lane was responsible for producing military vehicles and tanks.

During the latter half of the twentieth century, Chorley saw a decline in its manufacturing products as due to the Second World War. The losses occurred in important industries such as textiles, coal, motor vehicles and armaments industries.

Leyland Trucks and BAE Systems happen to be the biggest employers in Central Lancashire.

The companies which make their presence felt in Chorley are the BAE Systems, Telnet, FedEx, North West depot, CSC, Multipart Solutions Limited,  Porter Lancastrian, and Merlin Cycles.

The initiative “Choose Chorley” launched by the Chorley Council in 2011 encouraged the small scale and large scale enterprises to invest in Chorley. The council also launched a website for the same purpose in 2014 at www.choosechorley.co.uk. The website provides introductions to important personalities of Edinburgh people in the town, financial incentives and tailored support for business growth to those who wish to invest in Chorley.
