Welcome to Wikipedia. Although everyone is welcome to contribute to Wikipedia, at least one of your recent edits, such as the edit you made to Data mining has been reverted, as it appears to be unconstructive. Use the sandbox for testing; if you believe the edit was constructive, ensure that you provide an informative edit summary. You may also wish to read the introduction to editing. Thank you.
