Oracle is a product from Oracle Corporation that provides a relational database management system. RDBMS supports any kind of data model. It has different product editions, including Standard Edition, Enterprise Edition, Express Edition, and Personal Edition.
A database refers to the organized collection of structured data stored electronically in a device. It allows us to access, manage, and find relevant information frequently. The flat file structure was extensively used to store data before the database system was invented. The relational database approach becomes popular in comparison to the flat file model because it eliminates redundant data. For example, suppose we have an employee and contact information stored in the same file. In such a case, the employees with multiple contacts will show up in many rows.
The RDBMS system manages the relational data. Oracle Database is the most famous relational database system (RDBMS) because it shares the largest part of a market among other relational databases. Some other popular relational databases are MySQL, DB2, SQL Server, PostgreSQL, etc.
Importance of Oracle
It is one of the oldest database management companies in the world. It has always focused on enterprise needs and kept up with the newest technological developments. As a result, its products are constantly updated with new features. For example, the most recent Oracle database, 19C, is also available on Oracle Cloud. Oracle allows users to select from various database editions to meet their specific demands with a cost-effective solution.
Availability: It is never offline or out of service that means supported 24*7 availability of the database. It provides high availability of databases because of the Oracle Data Guard functionality. This functionality allows using of the secondary database as a copy of the primary database during any failure. As a result, all normal processes such as backups and partial failures do not interrupt the database from being used.
Security: Oracle has a mechanism for controlling and accessing the database to prevent unauthorized access. It provides high security because of the Oracle Advanced Security features. It offers two solutions to protect databases that are TDE (Transparent Data Encryption) and Data Redaction. TDE supports data encryption both at the source and after export. Redaction is performed at the application level. Oracle has some other security features like Oracle Database Vault that regulates user privileges and Oracle Label Security.
Scalability: It provides features like RAC (Real Application Cluster) and Portability, which makes an Oracle database scalable based on usage. In a clustered environment, it includes capabilities such as rolling instance migrations, performing upgrades, maintaining application continuity, quality of service management, etc.
Performance: Oracle provides performance optimization tools such as Oracle Advanced Compression, Oracle Database In-Memory, Oracle Real Application Testing, and Oracle Times Ten Application-Tier Database Cache. Their main objective is to improve system performance to the highest possible level.
