What is Data Aggregation? Examples of Data

2019-10-22  Data aggregation is the process of gathering data and presenting it in a summarized format. The data may be gathered from multiple data sources with the intent of combining these data sources into a summary for data analysis. This is a crucial step, since the accuracy of insights from data analysis

Data Mining Process an overview ScienceDirect

Chapter 2 Data Mining Process provides a framework to solve data mining problems. A five-step process outlined in this chapter provides guidelines on gathering subject matter expertise; exploring the data with statistics and visualization; building a model using data mining algorithms; testing the model and deploying in production environment; and finally reflecting on new knowledge gained in the cycle.

Basics of Cube Aggregates and Data Rollup SAP Blogs

2013-7-7  Basic purpose of using aggregates is to make data extraction faster. When we access the data frequently for reporting and we have huge amount of data it takes more time retrieve. If a query is frequently used for reporting and we want performance enhancement then we use aggregates on data source (at Info Cube).
