I've just started the exam and I don't understand a few things.
1. Apparantly, we have to write to and read from the database file they provided. Is this right?
2. Am I right in saying we don't actually use a database like Access, SQL Server or anything like that and that we don't use
JDBC?
3. If we don't use any database technology as mentioned in question 2 then how do we allow multiple concurrent accesses to the database file? Surely, only 1
thread can access (read, modify) the file at one time?
Thanks
