Data mining is the process of analyzing hidden patterns of data according to different perspectives for categorization into useful information, which is collected and assembled in common areas, such as data warehouses, for efficient analysis, data mining algorithms, facilitating business decision making and other information requirements to ultimately cut costs and increase revenue.
Data aggregation is a type of data and information mining process where data is searched, gathered and presented in a report-based, summarized format to achieve specific business objectives or processes and/or conduct human analysis. Data aggregation may .
Data mining is the process of discovering actionable information from large sets of data. Data mining uses mathematical analysis to derive patterns and trends that exist in data. Typically, these patterns cannot be discovered by traditional data exploration because the relationships are too complex or because there is too much data.

In computer programming contexts, a data cube (or datacube) is a multi-dimensional ("n-D") array of values. Typically, the term datacube is applied in contexts where these arrays are massively larger than the hosting computer's main memory; examples include multi-terabyte/petabyte data warehouses and time series of image data.. The data cube is used to represent data (sometimes called facts ...
Summarizing data, finding totals, and calculating averages and other descriptive measures are probably not new to you. When you need your summaries in the form of new data, rather than reports, the process is called aggregation. Aggregated data can become the basis for additional calculations, merged with other datasets, used in any way that other [.]

Jun 19, 2017· The data set will likely be huge! Complex data analysis and mining on huge amounts of data can take a long time, making such analysis impractical or infeasible. Data reduction techniques can be applied to obtain a compressed representation of the data set that is much smaller in volume, yet maintains the integrity of the original data.
Data mining is the process of analyzing large amounts of data in order to discover patterns and other information. It is typically performed on databases, which store data in a structured format. By "mining" large amounts of data, hidden information can be discovered and used for other purposes.
