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.

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
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.

Warrington is referred as unitary authority area in Cheshire with a population of around 208,800 recorded in 2016. It lies on the shore of the Mersey River. The town is referred as the largest town in the county of Cheshire, England. It is located between the towns of Manchester and Liverpool. The population of the town grew strongly since 1968, and it became a new town. The history of the area traced its root back to the Roman period. The Romans discovered the town at an important crossing place on the Mersey River, and the Saxons set up the new settlement of the town. Warrington developed as a market town at the lowest bridging point, a place which is crossed by a bridge at its closest point to the sea during the Medieval Period. The town was engaged in the business of textile and wool production in the middle ages.
The town experienced the urbanisation and expansion after the industrialisation took place in historical counties of England and when Mersey was made traversable in the 18th century. The vital railway corridors in the United Kingdom, West Coast Main Line, runs north to south and the Cheshire Lines connecting the towns of Liverpool and Manchester, runs west to east. The Manchester Ship Canal, 36 miles long inland waterway connecting Manchester to the Irish Sea cuts through the south of the town from west to east. The partial box is created around the town with M6 and M62 motorways. In 1974, with the combination of former County Borough of Warrington, the Lymm Urban District and the Warrington Rural District, the modern borough of Warrington was developed.
