Can you give some insights on how and when should I use them?\r\n\r\nAlso, I am particularly interested on how to handle errors when using the method `.create(...)`. I found posts both in your [documentation](http://docs.sequelizejs.com/en/latest/docs/instances/) and in [stackoverflow](http://stackoverflow.com/questions/19003148/sequelize-get-findorcreate-error) that refers to the `.build()` method and `findOrCreate()` but not for `create()` method. \r\n\r\n\r\nComments are highly appreciated.\r\n\r\nNote:\r\nI am using __sequelize v3.1.0__ and __tedious v1.11.0__."}}
