RDBMS v MongoDB

Schema = Database, Table = Collection, Partition = Shard, Row = Document, Column = Field, Returned Dataset = Cursor.

A document specialized database-engine that uses a human readable subset of javascript – called json – rather than xml.

er no … sorry. You can always join tables at the application level after uploading them – or just make a new table with the rows you need from other tables.

Joining sharded data would be very slow.

Only uses primary indexes/ keys. No need for foreign-keys if there are no relationships.

If you need a table indexed on another column – make a copy of the table – indexed on the other column.
