Question: A project is proposed to design a database to store details of laptops in a school. The shop has several laptops, where each laptop can be used by many users. Information to be stored about each laptop includes ID, users, type, and a list of software. Each chapter has exactly one main user and zero or more secondary users. A software has a unique name and validity. Each user has a name and a unique ID and it should be possible to search the database by users names, laptop IDs, and software keywords. Whenever any user uses a software on laptop, the date and time of usage should be recorded; this is used name and role (student, teacher, or administrator). r reporting when a software was last used, as well as recording the number of times a software was used. Each user is identified by a unique ID, has a
