O

racle 11g is by far the most robust database software on the market 
today. It’s also the leading database software used and sold all over the 

world. It has become an enterprise architecture standard for managing data, 
regardless of the data’s size or complexity. 

This chapter highlights the reasons to use Oracle 11g.

Introducing a New Kind of 

Database Management

Oracle is software that efficiently organizes data in a relational manner. 
Before Oracle, other database software ran on mainframes and used a hierar-
chical data model where data is stored in a tree-like structure as flat files — 
those crazy COBOL programmers!

The relational model is a concept where data is logically stored. These design 
elements are in the form of tables. Tables have columns, and the columns 
have attributes (character or number, for example). The tables are organized 
to store specific data. The tables relate to one another through primary keys.

For more clarity, Oracle, the company, was founded on the database soft-
ware that transformed the industry into what it is today. Oracle, the com-
pany, owns many software products and applications that it has written or 
acquired, but the database software is still Oracle’s core product. 

 

This book focuses more on database administration rather than Oracle appli-
cations administration.
