An oracle online course can be considered a great option to gain some practical knowledge about the databases. This article describes Oracle Database, its functionality, advantages, and other characteristics in detail.

What Is Oracle in Database Management System?

DBMS (database management system) is a software package which allows to store, modify and extract information from a database. The system assists in guaranteeing that data is properly, safe and accurate managed.

What is oracle in DBMS? Oracle database is the proprietary database system of the oracle company which is a leading database solutions provider in the world. In the Oracle, the data is stored in tables that are related to each other with the help of SQL (Structured Query Language).

Oracle is a high-end product that is meant to support applications in which you want to process large amounts of data securely, all at once. Oracle is capable of multi-user functionality and reliability. Oracle can be implemented either on premises or in the cloud or even in both at the same time.

How Oracle Database Works

The server-side component is the key factor in Oracle Database and it is based on client/server technology. Here the request is generated by the client and the server, which manages the databases, receives the request. When the user enters the query, the optimum execution plan is chosen, after analysing the query. Then the data is retrieved from the storage.

The two major parts of the system include the database instance and the physical database. Database instances consist of memory structures and processes responsible for executing queries, caching, and managing transactions. A physical database consists of actual data that is stored in data files, control files, and redo log files.

Oracle maintains consistency of transactions through commits and rollbacks. If a transaction fails, the partial processing is rolled back by itself, thereby maintaining the data integrity.

Key Features of Oracle Database

Following are the core features of Oracle Database which make it reliable and high performing in enterprise environment.

High Availability

Oracle Database has been built in such a way that it offers the best performance in terms of uptime using its high availability capabilities. Oracle Database uses fault tolerant design, clustering, and automated recovery techniques, thus reducing the downtime of systems.

Scalability

Oracle provides easy scalability that enables businesses to cope with rising numbers of users, huge amounts of data, and workload. Oracle is useful for small-scale systems as well as for enterprise-level systems that require growing amount of data.

Security

Security has become a great strength of Oracle. Encryption is used for securing data, while authentication can be done for verifying users. Role-based access control and auditing systems can also be utilized for keeping the enterprise data safe from any sort of intrusion.

Backup and Recovery

There are several backup and recovery options in the Oracle database that prevent accidental loss of data due to failure. The automation process for backup and recovery is available, which ensures quick recovery of data.

Performance Optimization

Oracle increases efficiency through the use of indexing, caching, and automatic query optimization tools. Such aspects guarantee efficient running of SQL statements, faster processing time, and efficient management of huge volumes of data, thus making the database very efficient.
