Oracle Database
Oracle Database is a multi-model relational database management system (RDBMS) developed by Oracle Corporation, widely used for enterprise-scale data storage and management. It supports SQL for querying and transaction processing, with features like ACID compliance, high availability, and advanced security. It is known for its scalability, robustness, and integration with Oracle's ecosystem of business applications.
Developers should learn Oracle Database when working in enterprise environments that require reliable, scalable, and secure data management, such as financial systems, large-scale e-commerce, or government applications. It is particularly valuable for roles involving complex transactions, data warehousing, or integration with Oracle-based software stacks like Oracle E-Business Suite or Oracle Cloud.
