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 Belfast

Belfast is the largest city in the northern part as well as the second largest city in the whole Ireland region. It is also the capital city. It got the status of the city during late 18th century. The city was the hub of the Irish linen suit, rope-making, tobacco-processing and shipbuilding industries. RMS Titanic recognised as the world’s biggest as well as beneficial shipyard. Belfast played a crucial role in the industrial revolution and emerged as world’s Industrial hub during late 20th century. In mid of the 1930s, the city continued a major aerospace and missiles industry. Also, the city is a centre for business, higher education, arts, law and much more.

George Best and Belfast International Airport’s are giving their services to the city. Belfast Lough is dominated by the commercial and industry docks  

Governance

In 1613, the borough status to the Belfast was given by James VI and I and In 1888 it got the official city status by Queen Victoria. The city is governed by Belfast City Council and is part of local government district council as well. It is being represented in both the Northern Ireland Assembly and British House Of Commons. Belford comes under Northern Ireland constituency during the elections to the European Parliament.

Geography

Belfast located on the western side of Belfast Lough and the mouth of the Lagan River. This location is ideal for the shipbuilding industry. Wolff and Harland had the most significant shipyard in the world when the Titanic was built. At the time of winter solstice which the shortest day of the year, the sun rises around 08:45 and sunset before 16:00.  

Climate

Belfast has a marine climate similar to the rest of the Ireland. The difference seen in the day-night temperature is very less. Because of the warming effect of Gulf Stream, the temperature of Belfast is milder as compared to any other location. Currently, there is five weather observing stations in the Belfast that are Stormont, Newforge, Castlereagh, Helens Bay and Ravenhill Road. The hottest night of Belfast is recorded as 19.6 °C in August 2001 at Whitehouse.

Areas and Districts

During the 19th century, Belfast had grown rapidly from a market town to an industrial city. The city is gifted by natural hills that surround it and ultimately increase the beauty of the town. Furthermore, it helps in the tourism sector of the city. The city centre of Belfast is divided into two postcode districts. These are BT1 (for the north hall) and BT2( for the south hall). The number of tourists is continuously increasing since 2001. For this, cultural quarters have been developed by the city council. It really helps in the economy of the city as local people expanded their business and earning their livelihood. The name of the Cathedral Quarter has been taken from the name of St Anne’s Cathedral.

One of the main outdoor venues is Custom House Square. It is considered as the best place for free concerts and street entertainment. Apart from the communication channel, the Irish language is highly promoted and encouraged in the area of Gaeltacht quarter in west Belfast.

Demography

The population census conducted in the year of 2011, and the population was 276,459. This strength of people makes it the fifteenth-largest city and eleventh-largest conurbation in the England. As per the records, the first half of 20th century, the city experienced a massive growth in population. This arose issues related to administration during 1971 as the town was lacking with facility and infrastructure. But with the time, the development works also got pace and situation got well.
