There isn't really a database for this, because PLA is a very variable mixture, particularly with different colours, that effects the temperature and consistency. There is a database of suppliers: [
reprap.org]
Any reputable supplier should be able to give you some basic settings to get you going (glass transition temperature, melting temperature, extrusion temperature), but in reality, it's still very much a 'feel' thing, which becomes easier as you get to know your printer and the software.
