Please Answer this question
You are asked to use pipes & filters architectural pattern to design software architectures for the following 2 programs.
a) The program A inputs a sequence of numbers, e.g. 3, 5, 7, 9, 4, 5, 8, and outputs 8 times of each of the input numbers, e.g. 24, 40, 56, 72, 32, 40, 64 …
b) The program B inputs one number k and outputs a sequence of k times 2i where i = 1, 2, 3, 4, 5, 6, … For example, when input is 3, the program outputs 6, 12, 24, 48, 96, …
For the architecture of each program, describe its module view with a UML class diagram and component-connector view with a UML composite structure diagram. Please note that for the two architectures, their module views must be same, but their component-connector views can be different. Hint: create a "doubler" filter class.
In the class diagram, according to pipes & filters architectural pattern, you should design the following classes: DataSource, DataSink, Filter, and Pipe. For each class, give name(s) of its operation(s). No attributes and operation signatures are needed. You should describe multiplicity for each association relationship in the diagram. No interfaces are needed.
In the composite structure diagrams, based on the class diagram, you should design components, component ports, and connectors between ports of two components. For each connector, give its role and connector type.
