Answer)

The system analysis phase is a part of the SDLC phase which involves the fetching and gathering of the requirement for the development of the system.This is the stage wherein the business would need a means to make the business process more efficient and also it focuses more on what the system would perform as efforts that would have the source of information.

The end product associated with the system analysis phase is as follows:

The activity or the phases which would have planning, analysis, implementation, design and the maintenance or the support of the events.

This would help in guiding of the project management activity in the information system development.

The functional decomposition diagram is which has the overall function or project which would have the necessary sub tasks for completing the project. The functional decomposition would help the project to have the problems solved when it comes to development of the business operations, or the computer programming and the machine learning.

The data flow diagram is defined to be the way of a representation which has the data flow of the process or the any system associated with it. The DFD would have a defined information with regards to the output and the input of the entity as well as the process associated with it. This would have no control flow and hence there is no such loops or decision rules.

The functional decomposition is meant for partitioning of the functionality of the complicated system as smaller and into smaller parts. Data flow diagram is the one which deals with the data flow via the system for the specific function of the system.

Both represent the process and data flow.
