EVE-Central provides an incredibly useful live price database that is easily queryable. Unfortunately, this data is only good for immediate processing. Other sites provide historical data, but only rudimentary manufacturing information. This means a large piece of the picture is missing from historical charting; the real costs of producing items.

So, the very first step in building a charting system is building a historical price database. Instead of relying on a start point from live data and croning the rest, EVE-Central provides free and easy access to the raw data files in CSV.
