### Data structure

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

```
{   
    'teams': {
        "67": "Uruguay",
        ...
    },
    'continents': {
        "4": "South America",
        ...
    },
    'events': {
        'world.1930': {
            'games': [...],
            'teams': [...],
            'rounds': {
                "2": "Round of 16",
            },
        },
        ...
}
```

### 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.
