The Role of Oracle Fusion Middleware
The growing popularity of Internet and intranet applications in the late 1990s led to a
change in deployment from client/server (with fat clients running a significant piece of
the application) to a three-tier architecture (with a browser supplying everything needed
for a thin client). Hence, middleware is an important part of any database connection
strategy discussion. Oracle's WebLogic Server enables deployment of the middle tier in
a three-tier solution for web-based applications, component-based applications, and
enterprise application integration. Oracle WebLogic Server is a key part of Oracle's Fu‐
sion Middleware, replacing Oracle's earlier generation Internet Application Server, and
is a component of Oracle's Cloud Application Foundation.
Other Fusion Middleware components address transaction management, data integra‐
tion, business process management, business intelligence, identity management,
service-oriented architectures (SOA), and portal, social, and content platforms (Web‐
Center). We'll introduce those after first describing the WebLogic Server.
