11 Providing Software as a Service

This chapter introduces Oracle TopLink features available for developing shared applications that run in Software-as-a-Service (SaaS) environments.

Use Case

Users want to establish an SaaS environment, where applications and data are shared by multiple clients.

  • TopLink 12c Release 1 (12.1.2) or later.

TopLink includes all of EclipseLink, plus additional functionality from Oracle.
