Introduction to ORACLE | Oracle Tutorial pdf

ORACLE is a powerful RDBMS product that provides efficient and effective solutions for major database features.
This includes:
=> Large databases and space management control
=> Many concurrent database users
=> High transaction processing performance
=> High availability
=> Controlled availability
=> Industry accepted standards
=> Manageable security
=> Database enforced integrity
=> Client/Server environment
=> Distributed database systems
=> Portability

An ORACLE database system can easily take advantage of distributed processing by using its Client/ Server architecture. In this architecture, the database system is divided into two parts:
A front-end or a client portion The client executes the database application that accesses database information and interacts with the user.
A back-end or a server portion The server executes the ORACLE software and handles the functions required for concurrent, shared data access to ORACLE database.
