Best way to mine data?

[Account Closed]

Hello,

I have a spreadsheet with the tax record info for over 500,000 properties in it.

My goal is to import the spreadsheet into a database that I can query for specific criteria- for instance- non owner occupied, value greater than, etc.

I would prefer to use a web based platform to do it so that I can download the property info that I query into a format that I can send to a company to do my mailers.

Any recommendations?

Thanks,

Mark
