Database administrators collaborate cross-functionally to ensure that infrastructure and applications are optimized so that they deliver the maximum benefits to both the business and the customers it serves.
Database consolidation is a key step in the journey to the cloud. Oracle Database 12c makes the process far faster and simpler, enabling the high density of schema-based consolidation—without requiring changes to existing applications.
To make this possible, a single, multitenant container database can now host many “pluggable” databases. Each database that is consolidated or “plugged into” the multitenant container looks and feels to applications exactly the same as the preconsolidated version. Besides speeding the journey to cloud, consolidation also simplifies management—a huge advantage for organizations now managing hundreds, even thousands, of databases.
Oracle Database 18c, is the latest generation of the world’s most popular database, and may be deployed on-premises and/or in Oracle Cloud running on general purpose hardware or engineered systems specifically designed for database workloads such as Oracle Exadata and Oracle Database Appliance. It provides businesses of all sizes with access to the world’s fastest, most scalable and database technology for secure and cost-effective deployment of transactional and analytical workloads in the Cloud, on-premises and Hybrid Cloud configurations. Oracle Database 18c adds new functionality and enhancements to features previously introduced in Oracle Database 12c, including:
- Multitenant Architecture for massive cost savings and agility.
- In-Memory Column Store for massive performance gains for real-time analytics.
- Native Database Sharding for high availability of massive web applications.
- Many more critical capabilities for enhanced database performance, availability, security, analytics and application development.
