Likely asked and already answered Q about simple db

Anyone know of a plugin, widget or other simple method to create a data table in WP then search with an input query and return a result? For instance 5000 records with a unique number eg. abc123 and a corresponding date field eg. 12/31/2011. Like a library card system. Query: is the card expired or not? Yes or no. Just fishin’ around for a quick and dirty way to keep a list online. Thanks for your time. I do not take it for granted.
