12 Data Mining Tools and Techniques What is Data Mining? Data mining is a popular technological innovation that converts piles of data into useful knowledge that can help the data owners/users make informed choices and take smart actions for their own benefit.
Data mapping is a process used in data warehousing by which different data models are linked to each other using a defined set of methods to characterize the data in a specific definition. This definition can be any atomic unit, such as a unit of metadata or any other semantic.
The term "privacy preserving data mining" was introduced in papers (Agrawal Srikant, 2000) and (Lindell Pinkas, 2000). These papers considered two fundamental problems of PPDM, privacy preserving data collection and mining a dataset partitioned across several private enterprises.

Disaggregated data refers to numerical or nonnumerical information that has been (1) collected from multiple sources and/or on multiple measures, variables, or individuals; (2) compiled into aggregate data—, summaries of data—typically for the purposes of public reporting or statistical analysis; and then (3) broken down in component parts or smaller units of data.
Mining for Data Cube and Computing, parallelized aggregation of data subsets and its results are then post processed to obtain the final result Computation of.

Our timetested data mining and reporting engines rest atop of a centralized repository of uptodate, standardized and aggregated data. Reports can be generated with oneclick or delivered directly to a designated user at a predetermined time.
curate data mining models over aggregate data, while protecting privacy at the level of individual records. One approach for this problem is to randomize the values in individual records, and only disclose the randomized values. The model is then built over the randomized data, after first compensating for the randomization (at the aggregate ...
Data mining is a technique that discovers previously unknown relationships in data. Data mining is the practice of automatically searching large stores of data to .

A classifier is a Supervised function (machine learning tool) where the learned (target) attribute is categorical ("nominal").. It is used after the learning process to classify new records (data) by giving them the best target attribute ().. Rows are classified into buckets. For instance, if data has feature x, it goes into bucket one; if not, it goes into bucket two.
