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 Dereham

Located in the English county of Norfolk, Dereham is situated on the A47 road.The civil parish with an area of 21.51 km2 has a population of 18,609 as of 2011. Dereham is administered under the district of Breckland. The town of Dereham is different from West Dereham which lies 25 miles apart.

Early history

The town of East Dereham has a Neolithic history. This is indicated by the findings that the archaeologists uncovered in 1986. A greenstone axe head of the Neolithic period was found near Dereham. Findings included some tools and flint scrapers. Also found in the nearby fields were worked flints in the 1980s. Evidence of the existence of civilization during the Bronze Age also was found in 1976. Burnt flints from a potboiler were excavated from one site and another burnt mound site was also discovered in 1987.

In 2000, finds were discovered that belonged to the Iron Age. Earlier in 1983 pottery sherds were also found by field walkers. It is believed that the Roman Road that linked Brampton with Fen Causeway passed through Dereham. Some pottery and furniture of those times have also been excavated from the nearby fields.

The town may have got its name from a deer-park in the town even though it is believed that Dereham existed prior to the Saxon era even.Saint Wihtburh, daughter of the King of the East Angles, became a monk after seeing a vision of Virgin Mary and founded a monastery there in the seventh century. Edmund Bonner was the Rector for Dereham for a period of around four years from 1534-1538. A number of buildings that had stood in Dereham since long were destroyed in the fires that broke out in 1581 and 1659. Buildings that were not engulfed by the fires included the Bishop Bonner's cottage and the Church of Saint Nicholas'. Before being taken over by Queen Elizabeth I, Dereham’s administration fell to the Abbots initially and then the Bishops of Ely.

Napoleonic Conflict

The Dereham Church’s Bell Tower was used, in the late 1700’s, as a jail for French prisoners. A French Officer, Jean de Narde, on 6 October 1799, tried to escape from the tower but due to the presence of the guards,  he hid in a tree. He was spotted and asked to surrender. When he did not surrender, he was shot dead. Jean de Narde lies buried in the churchyard even today. A memorial stone was erected in 1858 on his grave which bears the engraving"Once our foes but now our allies and brethren." A documentary that goes by the name of  "Once our Foe - The shooting of Jean DeNarde" tells the same story.

Sport and leisure

As of now the earlier areas, which either fell under the railways or the industries, are now being used for leisure or sports purposes. Today the Dereham Leisure Centre, which is built on the remains of old railway locomotive depot, includes the following facilities:

  • a swimming pool,
  • facilities for dancing and sports
  • a gymnasium

The Dereham recreation ground provides the citizens with open-air tennis courts, skate park and equipment for the kids to play various games. Tenpin bowling alley is also offered in Strikes.

The Dereham Town F.C which plays at the Aldiss Park is a Non-League football club. The Dereham Rugby Club play in the Woodfordes  League at the Moorgate Road.Dereham also has its team of cricket and hockey. They are Dereham Cricket Club and Dereham Hockey Club respectively.
