I would really really suggest reading up on OSM before you start on your thesis. The complete OSM data is available from planet.openstreetmap.org , regional extracts from a number of places, for example: http://www.geofabrik.de/data/download.html |

Don't spent time building tools that are available. For example, there are tools that do all this work for you for full history dumps. From the little we know about what you want to accomplish, I'd guess you don't need history files, just current state of the map. This can be easily accomplished using GDAl within OSgeo and then importing the result into SQLite. I'm sure there are a lot of other options too. |
Nodes are not sufficient for routing, you will need ways, too. And maybe relations for supporting turn restrictions and other advanced routing information. See routing in the wiki.
