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 Sunderland

Sunderland is a coastal city lies at the mouth of the Wear River, around 80 meters above sea level. It is located in the centre of the City of Sunderland metropolitan borough, local government district in England with a population of around 174,286 according to 2011 census. It is situated about 10 miles southeast of Newcastle and 240 miles north of London. The River Wear flows through the centre of the town and divides in a deeply incised valley. The town’s name is originated from sundered land meaning land kept aside for a special purpose or land sundered. The evidence of three settlements found historically in a county in North East England or County Durham on the site of present-day Sunderland.

The area of Sunderland Monkwearmouth is located on the north bank of the Wear River and settled in 674 during the foundation of Jarrow Abbey by the Benedict Biscop. Another settlement Bishopwearmouth founded in 930, lies at the southern side of the river. The town developed as a port over a period and became famous for trading salt and coal. The construction of ships started on the river in the 14th century. With the passage of time, the port of the town absorbed Monkwearmouth and Bishopwearmouth by the 19th century. The town became the major centre for the automotive industry and the service sector. It has been suggested that the person who is born or lives in the town, sometimes known as Mackem. The concept came into existence in the late 20th century and not used until 1980.

History

The early inhabitants of the town were the hunter-gatherers during Stone Age. The remains of the period were found during the excavations of St Peter’s Church in Monkwearmouth including the artefacts and microliths. The area of Hastings Hill became a primary place of burial and central point of activity in the Neolithic period, the final phase of the Stone Age. In the pre and post-Roman period, the area was occupied by the Brigantes around the Wear River. During the Anglo-Saxon era, the town became an important centre of knowledge and learning and library with approximately 300 volumes was also located in the town.  

The long trench, a tactic of warfare was found as one artefact of the English civil war. In the 17th century, the three original settlements (Monkwearmouth, Sunderland and Bishopwearmouth) were integrated and known as Sunderland-near-the-Sea. The factors behind the incorporation included the construction of ships on the banks of the river, salt panning and success of the port of Sunderland. The construction of Sunderland barracks was completed in 1794. These barracks included the 80-bed hospital, soldier’s quarters and housing for 1528 infantry troops. The second iron bridge of the world was built in the town in 1796.

The town was severally affected by the major Indian epidemic Cholera, broke out in the town in 1831. The disease spread in other parts of the country resulted in the death of more than 32000 people. The town again suffered from the worst disaster of the Victoria Hall in 1883 leading to the death of 183 children due to lack of enough way to pass during a variety show. This led to the invention of the concept of push bar emergency doors. The economy of the town shifted to chemical and motor manufacturing after the fall of heavy industries in the early 19th century. The electric tram system arrived in the town in 1900, later on, these were replaced by the buses in 1940.

The town saw remarkable expansion in the shipbuilding business during the First World War and became the prime target of a Zeppelin raid in 1916. Approx. 2500 citizens of the town served in the armed forces during the war period. The town also attacked by the German bombers during the Second World War leading to the destruction of 4000 homes and death of 267 people in the town. The coal mining and shipbuilding industry declined and ended by the late 20th century resulted in the unemployment of the local workforce.
