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 Edinburgh

Edinburgh is the centre city of Scotland. The area is also under the jurisdiction of the council state.During the period of 15th century, it was also a capital city. The Scottish parliament runs administration from this city only. The king used to rule in the Edinburgh in the medieval era. Being a part of the Midlothian area, Edinburg has been known as a centre of learning for Scott Law, Medicine, literature, engineering and the various sciences. After London, it is the next important city for fiscal matters. Edinburgh has also become the United Kingdom’s second most common traveller terminus after London.

In a recent survey, the population of Edinburgh stood second in Scotland and on the seventh number in the United Kingdom.

The early burgh which looks like the Seven Hills of Rome is often said to be constructed on Arthur's Seat Calton Hill, Craiglockhart Hill, Corstorphine Hill, Braid Hill, Blackford Hill, and the Castle Rock. Edinburgh actually came up near the prominent Castle Rock.

There is a gap created by volcanic plugs millions of years ago between the Firth of Forth to the north and the Pentland Hills to the south. In addition to these, another hollow on the rock's south side formed a natural stronghold that formed the basis for building the Edinburgh Castle. The place from where the glacier receded is now occupied by the residential areas of Marchmont and Bruntsfield.
