8. A subsystem is a ..................... of classes, associations, operations, events and constraints
that are interrelated.
9. ..................... define an abstract world and work like a client of services for layers below

interacting.

11. ..................... is a flow-insensitive, context-sensitive static analysis tool for Java.
12. A ..................... diagram shows how the systems will be physically distributed on the
hardware.

13. ..................... control concerns the flow of externally visible events among the objects in the
system.
14. ..................... requires that objects must release the reserved resources.

15. ..................... is a system that simulates evolving real-world objects.

12.3 Summary

During system design developers devise the high-level strategy (system architecture) for
solving the problem and building a solution and make decisions.

Reuse is often cited as an advantage of OO technology. Reusable things include models,
libraries, frameworks and patterns. Reuse of models is often the post practical form of
reuse.
In a subsystem classes share common properties, have similar functionality, have the
same physical location, or execute on the same hardware.
