8. Architecture
The Power to Serve.
• Simple 2-Tier Architecture
• Pages dynamically rendered using Meta data
• No code generation or file based compilation
• Runs everywhere Oracle Database runs
11. Workspace
• Oracle Application Express enables a single database to
host large numbers of users.
• Users work in a dedicated work area called a
workspace.
• A workspace is a virtual private database that enables
multiple users to work within the same Oracle
• A workspace is a virtual private database that enables
multiple users to work within the same Oracle
Application Express installation while keeping their
objects, data and applications private.
• Flexible architecture enables a single database instance
to manage thousands of applications.
• It turns a single database into a hosted service, making
it an ideal platform for consolidation of smaller data
stores.
