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 Sheffield

Sheffield is also known as the Steel City to the entire world. In its prime during the 1900’s it was known for its industry. Today, however, this very same industrial city boasts of lush green parks. The city presents the localities and visitors with cultural scenes that include theatres, festivals, street arts, music and much more. Deriving its name from the River Sheaf, the city is located in South Yorkshire, England.

Transport

Road

Sheffield links to the national highway through the M1 and M18 motorways. The city centre is connected with the motorways by the Sheffield Parkway.

Rail

The following are the routes that pass through Sheffield:

  • The Midland Main Line
  • The Cross Country Route
  • Routes that link the cities of Liverpool and Manchester with East Anglia and East Anglia.

Sheffield now has a direct connection to mainland Europe with the St Pancras International completed. There are trains from France and Belgium that connect to Sheffield railway station. The express train known as the Master Cutler connects Sheffield to the capital city.

 In 2010 the ruling government announced in October 2010 that Sheffield and Leeds would be served by the same line, which will also connect to Manchester, due to the proposed High-Speed Rail network. Another line proposed to begin by 2025, the Yorkshire/East Midlands High-Speed line, will be in service by 2032.

Other trains that serve Sheffield are provided by TransPennine Express, Northern and CrossCountry. The city has five other railway stations. Meadowhall, the second largest station in Sheffield serves as a bus, rail and tram interchange. Other commuter stations include services from Dore and Totley, Woodhouse, Chapeltown and Darnall.

Coach

The National Express and the Megabus are two services that operate the coach services in Sheffield. National Express serves the interchanges at Sheffield, Meadowhall and Meadowhead Bus Stop. Megabus only serves Meadowhall. Sheffield is connected by the National Express route 560/564 to London Victoria Coach Station through Chesterfield and Milton Keynes directly. It operates on the route 12 times a day bi-directionally. The two services that connect Sheffield to Manchester and Heathrow/Gatwick Airports respectively are 350 and 240.The M12 and M20, which are services provided by Megabus, call at Sheffield on the way to London from Newcastle upon Tyne and Inverness respectively.

Canal

A system navigable inland waterways - the Sheffield and South Yorkshire Navigation (S&SY)  in Yorkshire and Lincolnshire – is mainly based on the River Don which runs for a length of 43 miles with 29 locks. These waterways connect Doncaster, Sheffield,    and Rotherham with the River Trent at Keadby and the Aire and Calder Navigation.

Air

The Sheffield City Airport in 2008 had to be shut down. The entire traffic from Sheffield was as thus to the Doncaster Sheffield Airport which is at a distance of 29 km from the city centre. The airport used to be the site of former RAF Finningley base. The airport opened to the public on 28 April 2005. In a year the airport is capable of handling a million passengers.

A link road that was inaugurated in February 2016 and connects Doncaster Sheffield Airport to the M18 motorway has reduced the journey time from Sheffield by approx. 15  minutes.

The East Midlands Airport is an hour's drive from Sheffield while Manchester Airport connects to Sheffield directly through an hourly train.
