1 Describe the "Virtual Shared Memory" and "Message Oriented Middleware" web applications architectural categories?

Answer

Distributed Object Middleware (DOM)
This type of infrastructure allows to access remote objects transparently. It is based on the Remote Procedure Call (RPC) mechanism e.g., CORBA, Microsoft’s DCOM, or EJB (Enterprise Java Beans) by Sun Microsystems.

Message Oriented Middleware (MOM)
MOM systems offer functionalities for asynchronous transmission of messages. MOM ensures that messages are delivered nevertheless. Examples of MOM systems include Sun’s JMS (Java Messaging Service) and Microsoft’s MSMQ (Microsoft Message Queue).

4 How Architecture can be looked at from different viewpoints?
Answer
We normally distinguish between four different views:
The Conceptual view
The runtime view
The Process view, which maps processes at system runtime, while looking at aspects like synchronization and concurrency.
The Implementation view, which describes the system’s software artifacts, e.g., subsystems, components, or source code.
5 What are important properties of software architectures?
Answer

The most important properties of software architectures are:
Architecture describes structure.
Architecture forms the transition from analysis to implementation.
Architecture can be looked at from different viewpoints:
Conceptual View
Runtime View
Process View
Implementation View
Architecture makes a system understandable.
