    Awesome technology makes query fast. You can apply aggregate awareness to Dimension and Measure.

    Aggregate awareness is the ability of a relational universe to take advantage of database tables that contain pr-aggregated data (aggregate tables). Setting up aggregate awareness accelerates queries by processing fewer facts and aggregating fewer rows. If an aggregate aware object is included in a query, at runtime the query generator retrieves the data from the table with the highest aggregation level that matches the level of detail in the query. For example, in a data foundation, there is a fact table for sales with detail on the transaction level, and an aggregate table with sales summed by day. If a query asks for sales details, then the transaction table is used. If a query asks for sales per day, then the aggregate table is used. Which table is used is transparent to the user.Setting up aggregate awareness in the universe has several steps. See the related topic for more information.
