As far as I know, infinite.
Note that the means which holds the table just doesn't know of users, and all accesses are treated one by one. Think of the locking aspect too, and that this causes that only one at a time will be able to write. But again, in the end this has few to do with it because if 100 users deploy a write at the very same time, the means which holds the table will deal with them subsequently. Therefor locking is only to prevent from users overriding eachothers data.

According to a DBMS like SQL-Server, Oracle etc etc, it will come to the number of licencies for connecting to the database.

HTH,
