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 Inverness

Inverness is a town in the heart of Scottish Highlands. The Highland Council has its jurisdiction over the town. The location of the town is near to important battle sites. One of them is 11th century battle of Norway against Blar Nam Feinne. The battle was fought in the arid region. This city is located in the northern part of the United Kingdom just near to Great Glen. The River Ness enters the Moray Firth in the northeastern limit of the area. Since 2001 to 2012, there has not been much difference of population in these years. The Greater Inverness area had a population of approximately 60 thousand in 2012 including Culloden and Westhill regions. The counting of the Inverness comes under the fastest growing cities. The quality of life of this city ranked 5th among 189 British cities. It is the highest one among Scottish cities. In 2014, it got the status of the happiest place award in the Scotland region. This status was improved by one rank in the very next year and become the happiest city in 2015.

Population

As per the records of the National Records of Scotland, Inverness is recognized as the urban area west of the A9. In order to get the Inverness total picture, we need to include the villages of Westhill, Smithton, Culloden, and Balloch. It gives us an aggregate picture of each local area and its population. There only we can analyze the important factors for the development of the city.

Geography

Inverness is located near to place where River Nees started its journey. The other way to describe the location of the town is to say that it is at the southwestern end of the Moray Firth.

The city had also been affected by many earthquakes and the last one came in the year of 1934.

Climate

The climatic condition of the town is similar to Scotland i.e. oceanic. The city has been sheltered by many hills near to it which ultimately make the region dry most of the time. This city usually faces the extreme snowfall which went up to 1 foot 2 inches and created the record. The climate is much colder than the southeastern area of the Britain. In 2006, the city was recorded at the highest temperature.

Economy

Earlier the city was famous for distilling business but now the business has been shifted to High-tech industries such as manufacturing of diabetes diagnostic kits and its design. This business provides job opportunities to many skilled laborers and ultimately it booms the industry. The famous Highlands and Islands played a prominent role to expand this business by investing more and more in the industry. It ultimately becomes the hub for medical and its devices for a country. A large number of people is also working in the Scottish Natural Heritage i.e. SNH. The Ness Bridge and Friars Bridge also maintain the smooth conduct of the traffic in the town.

Government       

The royal burgh absorbed into a new district of Inverness and it becomes one of the eight districts within the Highland region. Under the Local Government Act 1994, the region became a unitary council area in 1996. The newly expanded region also includes the former districts which now turns to council management areas and created area committees individually for them. Among 80 seats of Highland Council wards, 23 belongs to Inverness committee.

City status  

In the year of 2000, the town of Inverness officially recognized as the city. The new corporate management areas thus formed got its favor. In 2008, a petition to matriculate armorial bearings was rejected by Lord Lyon King of Arms.
