Answer 1

30. An analyst, following the full SDLC development approach, may choose to utilize prototyping in the software development phase of the SDLC in order to develop the business requirements. The software development phase is the phase where the requirements and design prototyping are utilized to to develop the software according to the SDLC approach.

31. The child or primitive level diagram shows the program specifications based upon the processes. The child level is the child of the level 0 diagram so the child level diagram shows the program specifications.

32. The physical DFD of the current system shows how system operates and how system will be implemented so the physical dfd of the current system is used when working on a new development project.

34. Context DFD is the DFD for just one process.

36. UML diagram is used in the analysis and development phase as after the design phase of the UML diagram there is the anaysis and development phase.

37. The system analysts creates logical dfd of the current systemL

a.it explains events of systems and data required by each event.

b. It shows how business operates; not how the system can be implemented.

41.. Three phases are: Structure of process logic: here structure of the process is given

2.design: here we give design of process logic.

3.implementataion: here the implementation of the code is given.

42. The most important task is establish a good relationship with the user and develop detailed and complete user          requirements.
