As who would say, "I am Sir Oracle, and
when I open my lips, let no dog bark!" -William Shakespeare
(The Merchant of Venice)
Occasionally computer technology makes a
dramatic and significant break with the past and makes a quantum
leap. The relational model of database management, with its simple
tabular data structures and powerful data manipulation operations
is such a revolution. It all started with Dr. E.F.Codd, then of
IBM Research in 1969, when he presented the historical paper ‘A
relational Model of data for large shared data banks’ laid the
basic principles of the RDBMS. The relational model has helped
focus computer science research on the problems of data management
and relational database management system products have resulted
in tremendous improvements in accessing data and developing
applications. Although Object oriented database management systems
have started to appear, it is the common consensus of the
Information Technology pundits that the leading RDBM systems will
successfully incorporate object database ideas as an extension of
the basic relational model and will survive and thrive for many
years to come.
In 1979, Relational Software Inc. (which later
became Oracle Corporation), a small Silicon Valley company
introduced Oracle, the first commercial Relational database
management system, incorporating the SQL data access language.
Today, Oracle Corporation is the largest supplier of database
management and associated products in the world. Oracle 5,
released in 1985, was the first client/server database system. Now
the latest version of Oracle represents the industry’s most
advanced product implementing both the extended relational model
and the client/server architecture. Oracle7.x includes a
full-featured ANSI/ISO standard SQL. The Oracle7.x server can be
active part of applications, enforcing data integrity and business
rules through ‘declarative means’, that is without
programming, as well as through the industry’s most complete and
robust set of programming features, such as procedures and
triggers. Oracle7.x also includes industrial-strength, distributed
database facilities, enabling enterprise-wide access to data, no
matter where it is stored or on what kind of platforms. Oracle7.x
also maximizes the performance and reliability of on-line
transaction processing application through a range of
architectural features such as row level locking, on-line back-up
and recovery, and support for a wide variety of platforms.
This book is written with an aim to give you an
in-depth understanding of Oracle 7.x relational database
management system and its use in a client-server environment,
without burdening you with the complex details you will never use
or need. You will quickly learn to design, build and deploy
applications using Oracle7.x and other development tools which
makes application development in Oracle faster and efficient. The
Oracle’s SQL language and extensive facilities for enforcing
data integrity is given a through treatment. This book also
provides an excellent overview of database administration,
database security, backup and recovery, performance tuning,
networking and distributed database management.
This book explains the relational database
concepts from the very beginning and takes you step by step
through the application development-using Oracle 7.x. It also
introduces you to the latest tools available which will make the
application development easy. It also addresses the advanced
topics like performance tuning, database administration, etc. So
this book is for the end user and the database administrator, for
the novice and the experts.
