Hi,
I better understand your problem now. My idea would be to export your MS Access DB to a MySQL one. Then upload the DB to your website.
To export your MS Access DB :
http://server.bo-bo.si/php/dbfConverter/
http://www.cynergi.net/exportsql/
http://www.accessmysql.com/
http://www.churm.com/konvertr/
I used MyAccess and it perfectly worked. But there might be issues if your MS Access DB contains special features...
Maybe there's a way to use from command line so you would only have to set a cron job (Windows Task Manager) to export it daily, hourly... Whatever.
To update the online DB I developed a "stupid" but useful PHP tool : UQiQi. It allows you to update your DB from a .sql file. So if you create a cron job that calls the script... The DB is automatically updated.
But you first have to upload your .sql file on the website. Remote access from your website to your local .sql file is an issue. That's why you should use your favourite FTP client to upload your .sql file... An other cron job 😃.
MS Access DB -> MyAccess -> MySQL local DB > .sql > FTP Client -> UQiQi -> Website/MySQL DB.
I forgot what MyAccess generates... a .sql, directly access the local DB... Just try it 🙂.
Maybe MyAccess allows you to export and update a remote DB. I am sure there's a prosoftware to do it.
Curious... Why do they have to use Oracle ? Maybe you can advice them to hire you to develop a their E-Commerce website with PHP/MySQL 🙂
