However, the essential need is to perform data mining, aggregation, and analytics on this data without having any privacy and security concerns. Currently, there are many privacy issues that come with mining and aggregation of data.
"Data mining analysts turn data into information, information into insight and insight into business decisions," explains the Data Science blog at Southern Methodist University. However, data scientists also spend around half of their time cleaning data, at the very start of that chain.
Data aggregation and data mining are two techniques used in descriptive analytics to discover historical data. Data is first gathered and sorted by data aggregation in order to make the datasets more manageable by analysts. Data mining describes the next step of the analysis and involves a search of the data to identify patterns and meaning.

Data aggregation is any process whereby data is gathered and expressed in a summary form. When data is aggregated, atomic data rows -- typically gathered from multiple sources -- are replaced with totals or summary statistics. Groups of observed aggregates are replaced with summary statistics based on those observations.
