I've been asked by a client to make an online tracking system for work we do for them (we will be typesetting a high volume of books for this client). Basically, it would be a database showing the books we are currently working on, with information on what stage of the project we are at, and estimated completion dates. The only people with access to this system would be us and employees of the client company.
I've worked in MySQL and PHP before; should I just go with what I know? This answer to a similar question suggests using Google Apps. I don't have any experience with Python, but happy to learn...
