Aggregate Data Lecture Notes and Tutorials PDF Download

In statistics, aggregate data are data combined from several measurements. When data are aggregated, groups of observations are replaced with summary statistics based on those observations. In a data warehouse, the use of aggregate data dramatically reduces the time to query large sets of data. Developers pre-summarize queries that are regularly used, such as Weekly Sales across several dimensions such as by item hierarchy or geographical hierarchy.
