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 Lincoln

Lincoln which is situated in Lincolnshire, is a cathedral city and as per 2011 census had a population of 94,600. In the early periods, it was known as Lindum Colonia, a Roman colony. Lindum Colonia had come up from a settlement of the Iron Age that belonged to the 1st Century B.C. The settlement was the result of a deep pool and the name also probably comes from the word Lindon which was later converted to the Latin form Lindum. The full name for the location was  Colonia Domitiana Lindensium, which went by its founder, Domitian’s name. The colony was established within the walls of the hilltop fortress, to which an extension was also added later on, of an equal area.

Cathedral

First of all the construction of the Lincoln Cathedral began with the see being removed from the backwater of Dorchester-on-Thames, Oxfordshire. It was completed in 1092 but had to be rebuilt after a fire destroyed it. The cause of the fire is said to have been an earthquake that shook Lincoln in 1185. When the Lincoln Minster was rebuilt it had an added portion to the east.  The construction was completed on a superb scale with the crossing tower decorated by a pinnacle that rose to 525 ft, and considered to be the highest Europe has ever had till date. After the completion of all the three spires, the central spire is expected to be the tallest man-made structure in the world after the Great Pyramids of Egypt.

The Bishops of Lincoln were said to be one of the richest people in medieval England. The Diocese of Lincoln, considered to be the biggest in England, was home to more monasteries than the entire English counties put together.

When Magna Carta, the charter to bring peace between the king and rebel barons, was signed, one of the witnesses happened to be the Bishop of Lincoln, Hugh of Wells. There is only one copy that remains of the four originals and that is in the Lincoln Castle.

Lincoln Cathedral

The bishops of Lincoln who were most known were :

  • Robert Bloet
  • Hugh of Avalon
  • Robert Grosseteste
  • Henry Beaufort
  • Thomas Wolsey
  • Philip Repyngdon
  • Thomas Rotherham

Theologian William de Montibus was the chancellor and head of the cathedral school till his death in 1213. The Bishop’s Palace was the centre of administration. Built towards the end of the 12th Century, it was a magnificent building of that era in England. The East Hall of the Palace, designed by Hugh of Lincoln, is the earliest enduring example of a roofed domestic hall. Bishop William of Alnwick was responsible for building the other two parts namely the chapel range and entrance tower. It was he who also improvised upon the existing structure and lend a modern look to it in the 1430s. King Henry VIII and James I are said to have been e guests of the bishops at Lincoln Cathedral. Some royal troops ransacked the cathedral in 1648 during the civil war. The cathedral had another recent break-in due to which the stained glass had to be replaced.
