What is Oracle ?
Oracle is a relational database management system or DBMS. A DBMS is able to reliably manage a large amount of data in a multi-user environment so that many users can concurrently access the same data. All this must be accomplished while delivering high performance to the users of the database. A DBMS must also be secure from unauthorized access and provide efficient solutions for failure recovery. The ORACLE Server provides efficient and effective solutions for the major database features. ORACLE consists of many tools that allow you to create an application with ease and flexibility. You must determine how to implement your requirements using the features available in ORACLE, along with its tools. The features and tools that you choose to use to implement your application can significantly affect the performance of your application. Several of the more useful features available to ORACLE application developers are integrity constraints, stored procedures and packages, database triggers, cost-based optimizer, shared SQL, locking and sequences.
"Client Servers were a tremendous mistake and we are sorry that we sold it to you. Instead of applications running on the desktop and data sitting on the server, everything will be Internet based" - Larry Ellison, CEO, Oracle Corp.
