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 Darlington

Darlington is a large and historic market town and county in North East England with a population of around 92,363 according to 2011 census.

The World’s first steam locomotive passenger railway ‘Stockton and Darlington Railway’ was introduced by Quaker. The town is also known as Darlo. The town is surrounded by several suburbs include Harrowgate Village, Firthmoor and Skerne Park, Faverdale and the West Park. The twin towns of the Darlington are Amiens in France and Mulheim an der Ruhr in Germany.

It has been suggested that the town derived its name from the Saxon Dearthington meaning the settlement of the people of the Deornoth. The name of the town replaced by new name Derlinton during the Norman era. It is also known as Darnton in 17th and 18th century. The most important English church ‘St Cuthbert Church’ is built in the city in 1183 and listed as Grade I building, while the oldest church St Andrew was established in 1125 around the Haughton area of Darlington.

Darlington continued to grow as a small market town by the early 19th century. The Backhouse and Pease families, the strong Quaker families were significant employers of the town. The industrialist Joseph Pease constructed the clock tower, the famous landmark of the town in 1864. The face of the clock and tower bells were produced by T. Cooke and Sons and John Warner and Sons respectively. The tower bells of the clock tower are considered as sister bells placed inside the Elizabeth Tower at the Houses of Parliament, also known as Big Ben in London.

The town is also recognised for its corporation with the modern railway and this event is celebrated at Railway Centre and Museum of the Darlington. The town became the significant centre for manufacturing of railways in the 18th century. In 1825, Locomotion No 1 engine of George Stephenson was designed for passengers and goods and travelled between Stockton-On-Tees and Shildon via Darlington. The Hopetown Carriage Works was established in the town for supplying locomotives to the Darlington Railway. The three major works were developed in the town including Darlington Works, Faverdale Wagon Works and Robert Stephenson & Company.

The bridge building and engineering also played a significant role in the growth of the town. The headquarter of the large engineering firm Cleveland Bridge and Engineering Company is also located in the town and built Sydney Harbour Bridge, Tyne Bridge and the Humber Bridge.  The town is home to the leading engine building firms and industrial headquarters of AMEC.

The town is home to the largest private sector employer EE (Everything Everywhere) British mobile network operator and provided job to more than 2500 people. Other major employer of the town are Student Loans Company hired more than 100 people. Large engineering firms are based in the town such as Cleveland Bridge, Cummins, AMEC and Argos. Many modern and developing industries are also growing in the town including information technology.
