Why do We Use Oracle?

Performance & Scalability:- An Oracle database is scalable according to its usage thanks to features like Real Application Clustering and Portability. Oracle's Multiuser Database provides data consistency and concurrency control as part of its features.

Availability:- Applications that require real-time data availability must be highly available. Data is made available all the time in high-performance computing environments. While downtimes and failures are planned or unplanned, data is accessible, even if it is not set up for that purpose.

Recovery and backup:- Almost all types of failure can be recovered with its layout's complete recovery features. High availability demands that the database be recovered immediately in the event of failure. Data unaffected by the incident is available while those affected are being recovered.

Security:- A company's top priority is always to keep its data secure. It is possible to control how data is accessed and used in Oracle. Allowing distinct access to the users can be enabled by implementing authorization and editing user actions.
