We have to make a ballot system that makes users vote for various candidates

  • 0

We have to make a ballot system that makes users vote for various candidates on different positions. There’s a login for voters. How do you store a vote of one voter and then get that vote added to the previous votes? The only possible way is to store every vote on a database right? But what would the structure of the database look like? And how do you count it?

edit:
The voting system doesnt only have one group of candidates to vote. It has mayor, vice-mayor, senator, etc. There are too many. that’s why I’m confused. If only it was just a voting system of a president, it would be easier. So if I have a table for the voter, with a column of his/her voted candidate, it’s not possible since the voter votes for many candidates.

    A better way would be to have a different table to store Votes. And that table will have two attributes (VoterId, CandidateId)
    And you can fetch the Vote Count if you are allowing multiple votes from this table..

    But it would be better to make VoterId a Primary key in this table.. To avoid multiple voting

    CandidateType: – (TypeId(PK), typeName, maxVotePerVoterForThisType)

    Voter Table: – (voterId(PK), voterName, otherInfo)

    Candidate Table: – (candidateId(PK), candidateName, constituency,
    otherInfo, TypeId(FK))

    Votes:- (voterId(PK, FK), TypeId(PK, FK), candidateId(FK))

    *EDIT:- Schema edited with changed requirement in original post

    *EDIT: – Added a field in CandidateType table to allow multiple votes.(E.g.: Now a voter can vote for 10 Senators, if maxVotePerVoter for this type is set to 10..)
