ITPEC FE Morning October 2018 — Question 31 of 80
Data Mining — extracting new knowledge (trends, patterns) from large datasets using statistical methods.
Data mining uses statistical or other methods to discover hidden patterns, correlations, and trends in large amounts of data (big data).
Why not others:
- (a) Data dictionary — a catalog that describes the structure and meaning of data elements in a database
- (c) Data warehouse — a centralized repository that stores integrated data from multiple sources for analysis
- (d) Metadata — data that describes other data (e.g., file author, creation date), not a process
Key rule: Data mining = process of discovering knowledge; Data warehouse = storage for analysis; Metadata = description of data.
