DB_Loader_lib.php
- Contains the main functions used to load and interact with the Can-EWLAT database used by DB_Loader and DB_Loader_FileBuilder

DB_Loader.php
- Contains the main functions, file and header definitions. When loading the database this is where you'll want to update new input
files or change how the input files are structured. Commands in this class are also made to be run from the comman line in the format

php -r "require 'DB_Loader.php'; build_xxx();"

For example to reload all database tables from the files in the can-ewlat/data/csv/ directory ensure the files are properly defined


DB_Loader_FileBuilder.php

run_background_load.bat - navigate to the converter directory in a command line window and run this script to process the dataload
as four separate processes. This will speed up the time it takes to load the database.
