// Temporary Database
// Array of objects

// Documents in MongoDB have no structure restrictions.
// Documents work similar to JSON format in mongoDB.
// Documents have a key value pair (similar to JSON).
// No specific schema required before hand line SQL database.
// SO structuring the data is easier in mongoDB
