Q.Identify attributes needed for creating an Aadhaar Card.

When you think of a Voter ID card, the first image that comes to mind is probably a small plastic card with your photo and a few lines of text. That card is a physical token, but the real power lies in the data fields — the specific pieces of information stored on it and in the electoral roll database. For a commerce or humanities student, think of these fields as the columns in a giant spreadsheet that the Election Commission maintains for every eligible voter.

At its simplest, a Voter ID data field is a single, well-defined category of information about a voter. Each field has a specific purpose, and together they form a complete, verifiable identity. The most obvious fields are the ones printed on the card: your full name, your father's or mother's name (or spouse's name), your date of birth, your gender, and your residential address. These are not random choices — they are the minimum set needed to uniquely identify you and link you to a specific polling booth.

Why does this matter? Because the entire edifice of free and fair elections rests on one simple question: "Is this person who they claim to be, and are they eligible to vote here?" The data fields are the answer to that question. The name field prevents impersonation — if someone shows up claiming to be you, the polling officer can compare the name on the card with the roll. The address field ties you to a specific constituency, ensuring you vote only in the place where you live. The date of birth field confirms you are above 18, the legal voting age.

Beyond the printed fields, there are hidden data fields that matter just as much. The electoral roll database also stores a serial number within the polling booth's list, a part number (which section of the constituency you belong to), and a polling booth code. These fields are not on your card, but they determine exactly which building you walk into on election day. If your address field says you live in Colony A, but the polling booth code points to a booth in Colony B, there is a data mismatch — and you might be turned away. …
