Question

Assuming that you are designing a software to conduct a survey to collect data about how much time people do exercise in a day and save the results in a database. The survey will collect the information about the city where a person lives and the time the person does exercise in a day.

1. What modules would you have in the software system? List at least four modules based on the
model-view-controller structure.

2. Explain how you would use the GUI to collect the user data and save the data to a table in a
MySQL database.

3. Explain how you would retrieve the data from the table in the MySQL database and show the
data in the GUI.

Answer 1

Answer -

1. The modules that I would include in the software system would be :
   1. One of the module will be the module which would contain all the data that would be entered by the user or the data that the user would interact with . This is the module that would have all the data that the user enters or retrieve from the database of the software to change or read it.
   2. Next module would be the module that would contain the user interface for the user that is all the information to help in making a attractive and an easy user interface for the users so that user is happy to use the software and not confused as to how to use it or how chabby it looks. It would contain all the data as to how the front page or the form would look that the users would have to fill in.
   3. Next modules would be the module that would contain all the logic in it or the module that would actually control the interaction between the user and the data that they are entering into the software. This is the module which will contain the logic and all the requests that are made by the user would be monitored by this module. This module will help the software to respond to the user requests and to give them the output they desire.
   4. Next module would be the module which will look after the security or the protection of the software that is if anyone is not trying to access to the information of the people without the authorization and the entry of anyone is not illegal or if anything malicious for the software or not. It would contain all the firewall and the antivirus information for the software.

These are the four modules according to the model-view-controller structure which is the structure in which there is the module for the model that is the data and then the view of the software and last is the interface between the two that is the controller.
