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 Reading

Reading is a large town in Berkshire located in the Thames Valley with a population of around 162,700 recorded in 2016. The town is situated on the Thames and Kennet Rivers in southern England, and it is 42 miles west of London, 75 miles east of Bristol and 25 miles south of Oxford. The history of the town traced its roots back to 8th century. In the medieval period, the town was considered as a 10th largest town in England and served as the main trading and ecclesiastical centre.  One of the richest monasteries ‘Reading Abbey’ is also built in the town. The town was severally affected by English Civil war, and the wealth of the town declined with the major siege and loss of trade.

With the establishment of ironworks and Great Western Railway in the 18th and 19th century, the town grew rapidly and became the principal manufacturing centre. During that period, the economy of the town again flourished, and it became famous for its brewing trade. The town is crowned as leading economic area for economic success, and well-being and the factors contributing towards its growth are health, employment, and income. Due to its strategic location and establishment of information technology and insurance sector in the town, it became a major commercial and regional retail centre catering the needs of a large area of the Thames Valley.

It was also referred as Readingum, the name derived from an Anglo-Saxon tribe in Old English. The first battle of the town was held in 871, and an army of Danes set up the camp and remained in the town until the end of 8th century. With the presence of six mills, Reading was explicitly known as a borough in 1086. In the 14th century, the most devastating pandemics Black Death also affected the city and lost 60% of its population.

Reading Abbey founded in 1121 was largely destroyed during the dissolution of the monasteries in 1538. The town was little affected by First and Second World War compared to other towns and cities of the United Kingdom. The town centre was attacked by Luftwaffe plane machine in 1943 resulted in many causalities.
