For instance, in a billiards database, one record in the score table is a single score and has fields (a.k.a. columns) for the two players, the date, who won, and the number of balls remaining on the table, while one record in the player table contains one player's name, address, and playing skill.
In relational databases these are also called tuples, a term inherited from relational algebra.
Record may be present, and it is recommended that it be present if the server has transformed the record in any way.
A metadata record describing a resource on one database may differ substantially from a record for the same resource on another database; when a record replace is sent, it is desirable to indicate unambiguously the nature of the changes being made.
Either the change to the record or any subsequent processing may be delayed such that the response cannot say whether the operation was a success or a failure, as it hasn't yet been completed.
