Oracle Database is widely used in enterprise applications, ranging from financial systems to customer relationship management (CRM) software. It's known for its ability to handle large volumes of data, complex queries, and mission-critical workloads. However, it is often considered expensive and complex to manage, making it more suitable for large organizations with specific needs and resources. Oracle's cloud offerings have also become increasingly popular, allowing businesses to leverage its technology without the need to maintain on-premises infrastructure.
