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 Swansea

Swansea is a coastal city lies on the south coast of Wales with a population of around 241,300 in 2014. The county of Swansea is the second largest and most populous city in the Wales followed by Cardiff. The city is situated between the ancient Welsh and Glamorgan‘s historic county boundaries and surrounded by Bristol Channel and Swansea Bay. The city was also known as Copperopolis due to the presence of copper industry in the 19th century. The town got the city status in 1969 during the Prince Charles’s tour to Wales. The city comprises four physical areas include Gower Peninsula, urban and suburban zone stretching to the towns of Gorseinon, Lliw uplands and coastal strip around Swansea Bay.

History

The name of the city is derived from Sveinn’s island, referring settlement is developed on the raised ground in marshes. The early evidence of the area demonstrated the Bronze Age, Stone Age and Iron Age. It has been suggested that the city has developed as a Viking trading post. The first charter was granted to the city in the 11th century and it gained the status of the borough.  A marcher lordship was formed in the city after the Norman Empire and incorporated land around the manor of Kilvey, Swansea Bay and the peninsula. The borough charter was granted between 1158 and 1184 and gained the status of chief lordship town.

During the Industrial Revolution, the city served as the key logical base for copper smelting works. The wool, cloth, wine and coal was traded through the Swansea port. The population of the city expanded significantly in the 18th century. The lower Swansea valley was filled with waste products and derelict works due to decline in heavy industries in the town in the 20th century. The Lower Swansea Valley Scheme was introduced in the city to bring the wasteland into the usable condition. This resulted in the construction of Enterprise Zone over the wasteland and north and south dock became Parc Tawe and Marina respectively. The city was the prime target of German bombers during the Second World War due to the presence of the heavy industries in the town and the centre of the town was significantly affected.  

Economy

The economy of the city was based on metals, copper and mining industry in the 18th century.  These heavy industries declined and the majority of the copper ores were melted in the lower Swansea valley. The trend of the economy shifted to light industries and service sector. More than 90% of the workforce is engaged in the service sector including banking, finance, education, public administration and insurance. Headquarter of the Driver and Vehicle Licensing Agency is based in the city and provided employment to around 6000 people in the city while other major employers in the city include Virgin Media, Amazon, Admiral Group, BT and HSBC. The city is home to the worldwide customer care centre of the Virgin Atlantic, handling baggage claims, customer relations, reservations and sales. 

Education

The city has six infants, one nursery, five junior, fifteen comprehensive and seventy-seven primary schools in the city. The campus of Swansea University is located in the Singleton Park for higher education. The engineering department of the university has done an outstanding work for solving engineering design problems and acknowledged as a centre of excellence. The other departments of the university such as Physics, Computer Science and History were also renowned for their achievements. The third best medical school in the country after Cambridge and Oxford ‘Swansea University Medical School’ is located in the city. The other higher educational institutes are Gower College and University of Wales Trinity Saint David.
