The goal of the project is to share the data provided by the Baseball Databank files and Retrosheet.org in a format that allows users to easily load the data into a databases. Currently there are three officially supported databases PostgreSQL, SQLite and MongoDB. MySQL isn't 'officially' support, read this to find out why, but I do create backups and schema files for it.. There are schema files and backups for a Baseball Databank only db, a Retrosheet only db plus a combined database named Baseball Stats.

The schema files live in the schemas directory. With the schema files for all the database will have the folowing naming convention.

(mysql|postgres|sqlite)_(databank|retrosheet|combined)_schema_<season>.<version>.sql

Season is the latest season's data that is contained in the Baseball Databank files. The version number is the numbered release for the season's data. A new version is released if the Baseball Databank or Retrosheet release an update to their files. Releases are typically released on Sundays.

The backup files are included in each release. Since the files can be big, I've removed the backups from the repository. The naming convention is similar to the schema files.

(mongodb|mysql|postgres|sqlite)_(databank|retrosheet|combined)_backup_<season>.<version>.tgz

Season is the latest season's data that is contained in the Baseball Databank files. The version number is the numbered release for the season's data. A new version is released if the Baseball Databank or Retrosheet release an update to their files. Releases are typically released on Sundays.

The reason why MySQL isn't officially supported is due to the fact that there are 14 records that aren't in the pitchingpost table. The aren't there due to MySQL's decision to not support the inf value for infinity. Having said that there is support in the dbloader code for MySQL. If you choose to use MySQL just remember that you will not have all the data that is present in the CSV files.

I do not want to put some placeholder value in place of the inf simply because MySQL doesn't support it when PostgreSQL and SQLite do. If you can come up with a clever way of handling this for MySQL that isn't a complete hack feel free to pass it along or make a pull request.

If you wish to use this repo to parse and load the databases yourself, you should use the makefile. In order to connect to a database you need to pass in the username and password for the database you are going to connect to. For instance, If I wanted to load a postgres database I'd run the following:

make DB_USER=<db username> DB_PASS=<db password> postgresdb_db

In the future the utility used in this repository will be replaced by my csv-to project. I now use it for PostgreSQL and SQLite but it does not support MySQL at this point.
