This chapter looks at a technology that helps you to efficiently implement database security. The technology—called application context—was built to increase the performance of fine-grained access control (FGAC) implementations. The material presented here will provide the foundation for using application context as part of your security implementations. The examples are designed to be simple to allow you to focus on how the application context technology can be used.
For the discussions in this chapter, application context will be categorized into the following four different types:
