Android Question MySQL

Size:

This doesn't matter. There's no real difference if there are 10 rows in a table or 100 Mio. Really important how you design your database and your app. Loading thousands of rows is a programming/design mistake (except you need all the data to work with). At my work we handle Billions of rows.

Users:

It's all about how many requests/traffic they procuce. Here you will have a server handling all those requests and the database system like MySQL. The more traffic, the more power you need.

Best way:

Hm. There are several. I don't like RDC because you have to use the usserid and pw inside the app which is absolutely unsafe. I prefer php scripts on the server handling all the db requests.

MySQL:

It's free but there are other db-systems which may match better (for companies). For the "normal" stuff, it's ok, even in production systems. If you get bigger, you need a lot of money (servers). Think about Facebook and what db storage they need.

OK, understood, from the technical view, which tool is the easiest and beginners friendly to use with MySQL and B4A ?
