The project work constitutes a major component in most of the professional programmes and it is to be carried out with due care and should be executed with seriousness by the candidates. TYPE OF PROJECT As majority of the students are expected to work out a real life project in some industry/research and development laboratories/educational institutions/software companies, it is suggested that the project is to be chosen which should have some direct relevance in day-to-day activities of the candidates in his/her institution. Students are encouraged to work in the areas listed at the end. However, it is not mandatory for a student to work on a real life project. The student can formulate a project problem with the help of Guide. PROJECT PROPOSAL (SYNOPSIS) The project proposal should be prepared in consultation with your guide. The project proposal should clearly state the project objectives and the environment of the proposed project to be undertaken. The project work should compulsorily include the software development. The project proposal should contain complete details in the following form:

I want to create the data flow diagrams. write what should be the main process name? what should be the entities? what should i call the data flow between the entities and the main process and do the same thing with data flow diagram (abbreviated as DFD) 0, 1 and 2. in DFD zero what extra is added compared to context diagram? if it is the same as context diagram, there is no need to create data flow diagram 0.

Based on your Bank Management System (BMS) requirements, I'll help you create the data flow diagrams.
