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 Guildford

Guildford, a large town in Southern England is located on the A3 trunk road with a population of around 137,000 according to 2011 census. It is located 27 miles southwest of central London and it forms the Greater London Area’s southwestern tip. The town has been the seat of Borough of Guildford with 146,100 inhabitants recorded in 2015. According to the recent historical survey, Guildford came into existence as a result of a gap where River Wey was crossed over by the Harrow Way in the North Downs.

English Royal Mint was established in 978 AD and remained in the town until part way through the reign of William. The economy of the town boomed after being connected to a network of waterways on the building of the Wey Navigation and Basingstoke Canal. Guildford Cathedral and the University of Surrey were built in the 20th century. Guildford is considered as a robust commercial town and home to major businesses include Allianz and Sanofi, Lionhead Studios, Philips Electronics, Ericsson, Hello Games and Colgate-Palmolive. A number of leading companies including satellite manufacturers, medical and specialist gas providers are based in the Surrey Research Park. 

History

The history of the city traced its roots back to the Anglo-Saxon period. Some Bronze Age remaining including Roman villa has been found in the western Park Barn neighborhood of the town. After the abandonment of Roman period in Britain, Anglo-Saxon settlers developed the settlement as a small town. The population of the settlement grew as an ancient trackway Harrow Way crosses the Wey River by a ford. Although there are no clear pieces of evidence, it is assumed that Guildford Castle depicts the architectural style of Norman period. The layout of the castle was designed to overawe the conquered population. The status of the castle was then changed to the royal hunting lodge and granted to Francis Carter in 1611.

The remaining chamber of Guildford Synagogue was found in the High street in 1995. It is likely to be the Western Europe’s oldest remaining synagogue, but this remains a matter of controversy. The other notable building of the town includes Guildhall, which was built in the 14th century and still stands today. The Council chamber was also added in the existing structure and front façade of the building was decorated by the projecting clock. The Borough Council constructed 18 communal air raid shelters provided first aid and sanitation services during the Second World War.

The two pubs of the town were the prime target of Irish Republican Army and they planted a bomb resulted in the death of a civilian and four off-duty soldiers. Some suspects of this case also known as Guildford Four were found guilty in 1975 and sentenced to long prison sentences. Later on, they were released after a long legal battle and denied their involvement in the bombing. The town entered into the new phase of development in the 21st century and considered as one of the most expensive places in real estate sector in the UK outside London and ranked 9th in the Britain in 2006 for the best place to live in. The town is also ranked 27th for its pleasing and safe shopping destination in the United Kingdom.

Education

Guildford follows three-tier education system and there are several primary, junior and secondary schools in the town include Holy Trinity, Boxgrove Primary school, Guildford County school and Christ’s college. There are some independent schools in the town that include Royal Grammar School, Lanesborough School, Tormead School and Rydes Hill Preparatory School. For higher education, the University of Surrey and the University of Law has their campuses in the town, while other colleges include Academy of Contemporary Music and Guildford College of Further and Higher Education.
