As title, I am a programmer and offered a job in relation to 4D database work, but I never heard of this one, I did some research and found out it is a kind of old type of database technology that is not widely used nowadays, it is applied in a lot of legacy/law firms.
I am not a database coder or administrator so that I do not have any skill in database area, so just wondering is that gonna be an issue if I take this job? Or is it hard to learn it?
