The Oracle Server is a relational database management system that provides an open, complete, and integrated approach to information management. An Oracle Server consists of an Oracle database and an Oracle instance. The following are the features of the Oracle:
- Client/ Server Architecture- To take full advantage of the distributed systems, the oracle can allow processing to be split into client and server application programs. So, for the purpose of the distributed processing, it is based on client/server architecture.
- Large database and Space Management- Oracle can support the largest of the databases. It allows the full control of space used so that hardware devices can be used efficiently.
- High availability-It is never out of action or unavailable. Therefore, all the normal operations such as backups or partial failures do not interrupt the use of the database.
- Many concurrent database users- Oracle server minimizes the disputes between the data and assures data concurrency.
- Openness industry standards- Oracle follows the industry-accepted standards for the data access language, user interfaces, operating systems, and other network protocols. One of the advantages is that it is an “open” system that protects a customer’s investment.
- Enforced database integrity- Oracle enforces data integrity which is the assurance of the consistency of the data. As a result, the costs of coding and managing checks in many database applications are removed.
- Portability- Oracle software can be ported to work under a number of operating systems. Applications that are developed using Oracle can be ported to other operating systems without requiring any changes.
- Compatibility-Oracle software is compatible with the standards of industries. Applications developed for oracle is compatible with many other systems without a need for much modification.
- Controlled availability- Oracle also has a great feature of controllable availability and each and every level(even at sub-level). For Example, the administrator can also disable some specific applications to be packed or loaded without affecting other applications.
- Concurrent processing- Oracle allows a number of concurrent users to execute a variety of applications concurrently. A number of applications can be run at the same time by using Oracle.
- Replicating environments- Oracle software allows users to replicate groups of tables and their supporting objects to multiple sites.
- High transaction processing performance- Oracle also maintains a high degree of overall system performance. The database users do not suffer from slow processing performance.
- Manageable security- To protect against unauthorized database access and use, Oracle provides fail-safe security features to limit and monitor data access.
- Distributed systems- Oracle is based on distributed systems that have the same degree of user transparency and data consistency as non-distributed systems with the advantages of local database management.
