Non-aggregated measure in OLAP cube

Is possible to add a non-aggregated measure to an OLAP cube? fo开发者_开发百科r example I have a 'Datetime' field in my relational DB, and I would like to not use any kind of aggregation function when querying this measure of the cube. is there any scenario where this could be possible?

Generally you'll only have aggregate data in an OLAP cube, since the main purpose of the cube is to pre-aggregate the data.

While you could add the datestamp as a Dimension, and have each value in the cube representing a single record in your relational database, you'll lose much of the performance benefit of having the data in an olap structure.

A better way, if you need to drill-down to the level of individual transactions is to have your application transition to using the relational database for these queries.

Most of the time the underlying data would contain many different datetimes when queried, so what would the result for that measure be? Can you describe you requirement in more details?
