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 Carlisle

Carlisle, also known as the Great Border City as it has a common border with Scotland and England, is located in Cumberland at the convergence of the rivers Eden, Caldew and Petteril.   It serves not only as the administrative centre for Cumbria County Council and Carlisle City Council but is also the largest settlement in the Cumbria County.  Carlisle is known to have been a Roman settlement. Carlisle became an important military settlement during the Middle Ages as it enjoyed the closeness with the Kingdom of Scotland. One of the main attractions of Carlisle is the Carlisle Castle which was built by William Rufus in 1092 AD and was to be the prison of the Queen of Scotts, Mary. In the 12th Century, by the order of Henry I, a nunnery came up in Carlisle. A diocese came into existence somewhere in the 1130’s and the priory became a cathedral that is now known as the Carlisle Cathedral. Carlisle is a place of historic importance as all the greats such as Celts, Romans, King Arthur and Bonnie Prince Charlie have either ruled or lived.

Later, the Industrial Revolution saw the rise of the textile industry and the beginning of a social as well as economical transformation in Carlisle.

Attractions

  • The Carlisle Castle: The Carlisle Castle has stood here for nine centuries. The Castle was home to the King’s Royal Border Regiment and even held Queen Mary of Scotts as a prisoner. As of today, it is a place of an exhibition that showcases its history to the generation of the 21st Century in the form of exhibitions. The Castle also has Cumbria's Museum of Military Life that depicts the arms and other objects used by the military of the various kings in battles and wars.
  • The Carlisle Cathedral: Carlisle Cathedral is considered to be a magnificent piece that has been taken from the history of North West England. Having stood on the border for almost 900 years it seems to say a tale of its own. Even though it is not the biggest cathedral in England, it delights the visitors due to its religious connections. Visitors come here just not to see the cathedral but also to make worship to the Lord and praise Him. Here religion is no bound. Anybody from any religion can come and sit in the congregation at these services. Visitors come here to discover stories of faith, love and hope.
  • Our Lady and St Joseph's Church: Built in the early 1890's, this church is a Roman Catholic Parish church. The church has a building that is listed as Grade II.

Transport

Owned and managed by the Stagecoach, the bus station serves Carlisle. Located on the Dury Lane are the bus station that is served by a travel centre and seven stands. The present station was a replacement for a larger station at the same site. The replacement took place in the 1990s. Stagecoach in Cumbria and Arrestation at the iva North East are the main operators of the bus station in Carlisle.

Media

For around 48 years, 1961 to 2009, Carlisle played host to the Border Television that served the ITV Border region. After 1970’s Border Television suffered a decline in both the quantity and the range of its output. The premises of the Border Television were demolished after it shutdown operation in 2010. No programs were telecast till 2014. Border Television announced its return to Carlisle in 2014. As far as the printed news is concerned, it is taken care of by  The Cumberland News. The newspaper is published every Friday.
