Oracle’s Database 19c is a database management system that
allows corporate IT departments to control their large-scale computing
environments and developers to create enterprise-wide data management
programs and applications. Released in February 2019, it is the final
“long term support” release of the Oracle 12c family of products,
which also includes Oracle 18c. Currently, the company plans to
end support of the database in April 2027, and is currently offering
Oracle Database 21c as an “innovation release,” providing early
insight into the enhancements and new capabilities planned for the
product.

| Oracle Company Profile |
Oracle’s Database 19c database-management system was created for
corporate IT departments to help them better manage large-scale computing
environments. The product allows each database plugged into the
multitenant architecture to look and feel like a standard Oracle database
to applications, allowing existing applications to run unchanged.
| Vendor |
|
Oracle |
The open source system is Oracle’s flagship offering. It allows for
consolidation onto database clouds and engineered systems such as Oracle
Exadata and Oracle’s Database Appliance.
Database 19c offers database administration productivity
features for organizations looking to consolidate databases onto the cloud
without the need to modify or create new applications. It builds upon
previous releases and offers additional functionality for typical customer
use cases, including traditional transactions, real-time analytics, JSON
document stores, and Internet of Things (IoT) applications. It is also
designed for analytical database applications such as traditional and
real-time data warehouses and data marts, big data lakes, and graph
analytics. Database 19c lets users send write requests to the
standby, which are then redirected to the primary database, and then the
changes are shipped back to the standby.
New features offered in the release include an improved create
application wizard, REST-enabled SQL support, Web source modules, an
improved create page wizard, a new REST workshop, social sign-in
authentication, SQL quarantine, and workload capture and replay in a PDB,
among other features.
19c features:
- Application development
- Incremental capabilities in the areas of performance, security, and
high availability - Business intelligence and data warehousing
- Compression and archiving
- Oracle RAC and grid infrastructure
- Security
- Spatial and graph representation
- Unstructured data analysis
Oracle Database 19c is available in three main on-premise
editions for enterprise use – Standard Edition 2, Enterprise,
and Enterprise Edition on Engineered Systems.
Each is compatible with the other editions and shares the same database
engine architecture. This allows organizations to upgrade database
platforms as necessary. NOTE: Oracle Standard Edition
and Oracle Standard Edition One are no longer available for purchase.
Table 1 compares Oracle’s Database 19c editions.
| Edition | Standard Two | Enterprise | Enterprise on Engineered Systems |
|---|---|---|---|
| Description | Includes features necessary to develop workgroup, department-level, and Web applications. |
Provides performance, availability, scalability, and security for developing applications such as high-volume online transaction processing (OLTP) applications, query-intensive data warehouses, and demanding Internet applications. |
