Data Mining

Data mining is the process of discovering knowledge from databases that are being stored in data marts or data warehouses. The purpose is to identify valid, novel, useful, and understandable patterns in data. Data mining searches large databases for essential information for managing an organization.

Data mining involves five step processes:
-    Deciding between census and sample data
-    Identifying relationship within the data.
-    Modifying or transforming data.
-    Developing a model that explains the data relationship.
-    Testing the model’s accuracy.

Data Warehouse

A data warehouse is an electronic storage for databases that organizes large volumes of data into categories to support retrieval, interpretation, and sorting by end users. It provides an accessible archive to support dynamic organizational intelligence applications.

Data in a data warehouse must be continually updated to ensure that decision makers have access to the appropriate data for real-time decisions.

The more accessible the databases in the data warehouse, the more likely a researcher will use them to reveal patterns.
