Oracle Database Standard Edition 2 (SE2) is an affordable, full-featured database built for unprecedented ease of use, power, and performance. From single-server environments for small business to highly distributed branch environments, Oracle Database SE2 includes all the features necessary to build business applications. Despite it's competitive pricing it provides industry leading work-group scalability, availability and security for both OLTP and analytical workloads. It supports relational, JSON, XML, spatial, graph and unstructured data, enabling you to focus on building applications without having to worry about how to persist such data.
Oracle Database SE2 can be licensed on servers with a maximum of 2 sockets. However, the core counts per 2-socket server can increase over time without impacting customer license obligation. With Oracle Database SE2, customer license costs remain the same regardless of the number of cores in the socket.
