You are asking how feasible this approach is, but you provide no details about the restrictions and requirements. The only thing you did mention is needing the data to pass around in real time. You ask if it is a good idea to use a db, but that also depends on whatever you are trying to achieve. This question should be probably asked in software engineering stack exchange, and try to provide more details about your problem there. — kmaork 9 secs ago

Welcome to Stack Overflow. When asking homework type questions, rather than simply posting your assignment, please show your best good faith attempt to solve it – and then tell us what problems you're having. This will give us a better understanding of what you're trying to do, what you might be doing wrong, what you need help with. Please consult Open letter to students with homework problems and How do I ask a good question?. — Ivo Mori 48 secs ago
