### Data structure

A single JSON file is downloaded to provide the data set.  Its structure is as follows:

```
{   
    'teams': {
        teamId: teamCountryId,
        ...
    },
    'countries': {
        countryId: { countryContinentId, countryName }
        ...
    },
    'continents': {
        continentId: continentName,
        ...
    },
    'rounds': {
        roundId: roundName,
    },
    'tourneys': {
        eventName: {
            'games': [{ playAt, roundId, team1Id, team2Id, score1, score1et, score1p, score2, score2et, score2p }, ...],
            'teams': [teamId, ...]
        },
        ...    
    }
}
```

### Building the SQLite DB
Run `sportdb build` in the directory that has `Datafile`.  

Correspondence on the topic can be found at [this google groups topic](https://groups.google.com/forum/#!msg/opensport/jYNVDF_QSJA/pyHWWtRqAgAJ).

##### Troubleshooting: Using a Gemfile
Sportdb only builds with older versions of ActiveRecord. Use a Gemfile as outlined [here](https://groups.google.com/forum/#!topic/opensport/593H1O7yIdE) to lock the correct version.
