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 Canterbury

Canterbury is a historic cathedral city located on the River Stour in the Southeast England. It is located 55 miles southeast of London with a population of around 43,432 in 2011 census. The nearby villages and suburbs of the city include Rough Common, Harbledown, Tyler Hill, Hales Place, Sturry, and Wincheap.

The two wings further combine on the northeast edge of the city. Canterbury local government district covers the area of Herne and Whitstable Bay and Member of Parliament elected in the city is Rosie Duffield of Labour Party.

The city was redeveloped with the construction of the temple, public baths, theatre and roads with grid pattern by the Romans. They also built a wall with seven gates and an earth bank around the city to safeguard from Barbarians attack. After the abandonment of Roman period, Anglo-Saxon community developed within the city walls and trade developed in textile, pottery and leather sector.

Between 17th and 18th century, the castle of the city fell into disrepair and six gates were demolished. The silk industry was closed and trade was limited to only wheat and hops. The world’s first passenger railway came into existence in 1830 connected the town to a larger network of South Eastern Railway. The city was affected by First and Second World War destroyed 296 buildings and 731 homes and resulted in the death of 115 people. The redevelopment of the city took place ten years after the war and ring road was constructed to avoid growing problem of traffic congestion along with the development of Christ Church College and the University of Kent at Canterbury.
