Database collection access

Hi, I need to create a form page to collect information from a visitor, store the collected data in the database and notify the admin of new data. The best way for me will be to sync wix database, with my external DB, so I can have my offline application using that data. How can I sync Wix DB with my own?
Alternatively, I could email a CSV file every-time there is new submission, then import that CSV to my app.

Have a read here of working with external databases.

HI,

Thank you so much for such a prompt reply. This is very helpful. However, I was hoping to make a use of the internal WIX DB, and only access it from outside application. Is it possible?
