Question: I am in search for a database with translations so I can have comonly used phrases and words translated by a machine and not by an expensive translator. Is there such a thing as a translation database with words and often used phrases?

If you don't know any would you use such a service?

edit: the database should only be monitored by people and not some automatic translater since they tend to be VERY bad

Answer: 
Check: [open-tran.eu](http://open-tran.eu/). It is a database of translations taken from various open source projects.
So what you want is a database phrase book? What do you want that for? You can't use a phrase book to translate books or software etc. You can't use machine translation either, even though it can be a useful tool to start with. You have to use human translators wich know the source and target-language well, preferrably a bi-lingual person.

The only thing a phrase book is good for is asking directions; and not understand the answer... ;)
