Oracle server consists in a complete set of application constructors and products for users, with the one and only purpose of ensuring complete solutions in the information technology. Oracle applications are portable over a large number of work stations and operating systems, from personal computers to parallel processors. Oracle server is fitted with a flexible management system for databases, which is very good for the stocking and management of the information used by the applications. Oracle server is the most advanced server of Oracle and it leads a database with all the advantages of a relational structure. It also has the ability to stock and execute database typed objects, like procedures and safety mechanisms.

Security comparison Oracle & IBM DB2:

The Oracle server has a DBMS that controls the stocking of data, recovering of data through adequate optimization techniques, security of the databases and tasks allowed for particular users and consistency and protection of the data, including task archiving and search engines. The communication and integrity of information when the database is distributed in a network is also one of the strengths of Oracle server.

Application level comparison Oracle & IBM DB2:

The Oracle applications must be run on the same computer with the Oracle server. Alternatively, the applications and the utilities they use may be run on a local system for the user, while the Oracle DBMS runs on another. In this client - server environment, a large amount of resources may be run. For instance, an Oracle Forms application can run on a personal computer, while the access of data is conventionally led by an Oracle Server on a central computer.
