Databases for web app

I am looking to build a web app that will (hopefully) have multiple users. Do I construct one database with multiple tables or a database per user.

The app will be a logging system. Each user will be able to enter in information for each event and also see how things trend over time. Basically its like an app for tracking what you eat except it for tracking and logging trades that you make.

If I choose the single database how hard will it be to change later?

If this question isn't clear enough please let me know and I can clarify some more.

Since the app controls individual access to the database, a single database would be sufficient.

Each table in a database tracks records for a specific model. So whether it be a Trade Record or other table, the table row containing the record would have an element that identifies which user it belongs to. The app would prevent users from accessing rows that don’t match the current user.

Post back if you need more help. Good luck!!!
