Timeshare For Sale By Owner is a company in Orlando, FL that helps timeshare owners resell or lease timeshares and points. It's largely a cold-calling, telemarketing business. They had a Microsoft Access database they used to keep track of several thousand sales and customers. I was hired to convert their Access database to a LAMP platform. The conversion script is available, but the rest is left out to protect the client's information and processes.

This is the first time I used COM and Microsoft Jet in PHP. The script does several million loops during its execution and sucks up a lot of memory. If this script were used for more than a single one-time conversion, it could do with a bit of optimizing.

I heard a rumor, after I left, their regular tech guy denormalized the database structure I created because he didn't like table join queries, so the script is probably no longer representative of what they're using now.
