Create Database using LabVIEW

[harireddy7]

I need to create a database of list of 5-10 users containing the username, account number, mobile number, fingerprint. And verify whether the user is authorized or not based on the fingerprint.
How can I do this in LabVIEW or what steps should I follow to reach the output?

According to your specifications, there is no field that defines authorization. Is the mere presence in the database sufficient?

It would be a more interesting problem with millions of users, but with less than a dozen, "search array" on the array of fingerprints is probably all you need. How is the user database stored (array of clusters?).

Dr.JDPowell has a fantastic SQLite package available on VIPM.  If you're looking for an easy-to-use and portable database, SQLite's the way to go.

You could also dump all of that data into a binary file, or a TDMS file.  I'm partial to binary files for overhead reasons, but if you're only ever going to have 5 users, it really doesn't matter.

yes. Fingerprints & related info of user should be pre-stored.

And i'm using fingerprint sensor, using which i need to recognize whether the user's info is pre-stored or not.

just his/her info should be present in the database.

I have no idea where to start & how to create database!

Help needed!

How is the fingerprint stored?

That is what im asking.

How can i store fingerprints & search it later for recognition?

Well...

First, you'll need to look at the fingerprint sensor's documentation.  The vendor probably provided a dll to use to communicate with the sensor.  After you've established how the fingerprints are scanned, and brought into memory, you'll have a more informed view of how to best store them.  The FBI uses wavelet compression to store images of fingerprints, your machine may just return a hash value for each fingerprint, or it may return a bitmap.  Won't know for certain until you've read the documentation.
