This folder is left blank and the corresponding .gitignore ensures this. Every user should create symlinks where he wants the database files to be stored. Those symlinks could look like this:
Setup_2014_07_EPT_Prod -> ../../ant-database/Setup_2014_07_EPT_Prod
Then ../../ant-database is outside of this repository and can, for example, be stored on blaster and sshfs'd to your local machine.
It is also a good idea to use git again in those database folders in case something is messed up or for backup/migration purposes. However, the database can get quite large, so it was separated from this code repository.
