Documentation

Tool for dumping VDV 451 data into a database

This is intended to quickly analyze the content of a collection of VDV files in the VDV 451 format. By running this script a new schema is created and filled with one table per inuput file. Some known primary key mappings are used, you can add more using a config-file (see development.ini.dist for an example).

After dumping the data a SQL script apply_constraints.sql is run with the new schema. It sets foreign keys and indices. You may want to modify that to fit your needs (some errors are to be expected if you didn't create all tabels referenced there).
