Hi all, excuse the crosspost, I'm looking for a variety of opinions.

I'm just starting to think about my final year project and was mulling
over the idea of creating an e-commerce website (ASP, PHP, MYSQL,
Access... undecided yet,) that is updatable locally from an offline
database, which is then synchronized over the Internet (is there a
ready made control for this?) so as to keep up with transactions and
replenish stock levels, add new items etc... I would also like to use
tools that allow for 'transactions' so there is a rollback if failure
occurs - infact there's quite a lot of stuff i'd like to do.

Now my question is, what is the best combination of development tools
(database, language, CGI) to do this and would you consider it too
hard/easy for a final years project?
