Data+matching

What is data mining? Data mining is the discovery and extraction of hidden predictive information from large databases. It uses statistical methods and artificial intelligence technology to locate trends and patterns in data that would have been overlooked by normal database queries (Beekman, 2009) A grocery chain used data mining to discover differences between male and female shopping patterns, so they could create gender-specific marketing campaigns.

What is Data Matching? An activity involving the comparison of personal information from different sources, including sources within the same government institution, for administrative or non-administrative purposes. The data-matching activity that is established can be systematic or recurring. The data-matching activity can also be conducted on a periodic basis when deemed necessary. Data matching also includes the disclosure or sharing of personal information with another organization for data-matching purposes. (The Treasury Board of Candian Secretariat) If you took the information you had to the government and wanted to find out what information they had on you.
