What is the goal of middleware? Give examples of middleware.
What will be an ideal response?
The machines that compose an arbitrary distributed system are heterogeneous—different
hardware running different operating systems communicating across different network
architectures. Middleware helps provide portability, transparency and interoperability in distributed
systems and hides heterogeneity of the distributed system.Middleware facilitates communication
and cooperation among the various components of a distributed system by hiding
low-level implementation details from users and applications developers.Middleware employs
standard programming interfaces to enable interprocess communication between remote computers.
Standard programming interfaces are machine independent and provide portability and
transparency. Java RMI,CORBA and DCOM are used to create middleware.
