An aggregate is a collection of data that we interact with as a UNIT. Aggregates form the boundaries for ACID operations with the database. Key value, document, and column FAMILY databases can all be SEEN as forms of aggregate oriented database. Aggregates make it easier for the database to manage data storage over clusters.

Aggregate oriented databases work best when most data interaction is done with the same aggregate; aggregate IGNORANT databases are BETTER when interactions use data organized in many different formations. Aggregate oriented databases make inter aggregate relationships more difficult to handle than intra aggregate relationships. They often compute materialized views to provide data organized differently from their primary aggregates. This is often done with map reduce computations.
