What is a subsystem in UML?
In UML models, subsystems are a type of stereotyped component that represent independent, behavioral units in a system. Subsystems are used in class, component, and use-case diagrams to represent large-scale components in the system that you are modeling. You can model an entire system as a hierarchy of subsystems.
What is difference between package and subsystem?
While a package simply groups elements, a subsystem groups elements that together provide services such that other elements may access only those services and none of the elements themselves.
What is the sub system of use-case?
In the UML, a subsystem is a component, which is in turn a kind of structured class; therefore a subsystem is a class that is composed of parts represented by object roles. Use cases exist within a structural context. In the case of the system, this context consists of the system and associated actors.
What is a subsystem component?
A subsystem component is an Integration Flow Designer object that represents or references another system that you have already defined. The concept of a subsystem component is that it enables you to reuse a system.
How can we identify a sub system?
By rearranging the rows and columns of the interaction matrix into a pattern which resembles a block diagonal structure, the blocks can be interpreted as subsystems which can be identified by a later process.
What is a subsystem in design?
A Design Subsystem is a part of a system that encapsulates behavior, exposes a set of interfaces, and packages other model elements. From the outside, a subsystem is a single design model element that collaborates with other mod elelements to fulfill its responsibilities.
What is a subsystem in Object Oriented design?
Subsystems are object-oriented constructs that are classifiers as well as packages: a subsystem can have instances (if the designer so indicates). UML provides another way to model groups of global variables and procedures in the utility, which is a stereotype of class – the utility has no instances.
What is subsystem with example?
A unit or device that is part of a larger system. For example, a disk subsystem is a part of a computer system. A bus is a part of the computer. A subsystem usually refers to hardware, but it may be used to describe software.
What are subsystems?
A subsystem is a single, predefined operating environment through which the system coordinates the work flow and resource use. The system can contain several subsystems, all operating independently of each other. Subsystems manage resources. All jobs, with the exception of system jobs, run within subsystems.

What is difference between use case and test case?
A use case tells how a System will behave or perform a certain task provided the given conditions and a test case contains the actual test data, set of instructions to system and expected result of the interaction with system.
