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 Wokingham

Wokingham meaning ‘Wocca's people's home', situated 6 3 km from London to its West, and having a population of 30,690 is a market town. Wokingham, before 1974 when the local government was reorganized, was a borough. To form the current Wokingham District, it merged in 1974 it merged with Wokingham Rural District. Wokingham achieved the status of a borough in 2007.

Governance:

Northern Wokingham, at one time, was a detached part of Wiltshire that extended into the centre of the town – the area currently occupied by the Norreys, Bean Oak and Dowlesgreen estates. In 1844 it became a part of Berkshire. The then existing parish, in 1894, was divided into rural and urban civil parishes.

The Municipal Corporation Act of 1835 left Wokingham unformed. The Act was reformed in 1883. Due to the Local Government Act 1972, in 1974,  Wokingham and Wokingham Rural District merged to form the non-metropolitan district of Wokingham.  Formed as a unitary authority in 1998, the district has 54 elected councillors presided over by an elected councillor who manages the district and chairs (as a Chairman) all the meetings for a full year. The elections take place in three out of four years for the Chairman Councillor. Since 2002, the Conservative party has been in the seat with a majority. The Shute End is home to the Borough Council Offices in Wokingham.

Topography:

Located on the Emm Brook kin the Loddon Valley in central Berkshire, Wokingham is 33 miles west of central London and between the towns of Reading and Bracknell. Wokingham originally happened to be just a piece of agricultural land on the western front of the Windsor Forest. Wokingham’s soil is rich in loam and has a subsoil of gravel and sand.

The Wokingham town centre is replete with residential areas in almost every direction. The residential areas in the east are home to Dowlesgreen, Norreys, Keephatch and Bean Oak, in the west are Woosehill and  Emmbrook in the northwest. To the south, the areas include Wescott and Eastheath. Other residential areas include Woodcray and Luckley Green which have been present for a long time.

The last 8 decades have seen a lot of development in Wokingham. Dowlesgreen and Woosehill were built on farmland in the late 1960’s to the early 1970’s. Bean Oak was also developed during the same period. Keephatch came to be built in the '90s decade. The Norreys Estate came into existence in the 1960s. The  Norreys Avenue is. however, the oldest residential road having been built in the 1940’s. Norreys Avenue shaped as a horseshoe is located on Norreys Manor (now demolished). Because of this much of the manufactured houses were styled like those belonging to the 1940’s.The road also is home to some brick houses and to three blocks for police residential quarters.
