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, ...]
        },
        ...    
    }
}
