COMPLETE SOLUTION.
Heuristic Answer - Learns by acting, uses trial and error, values experiences,
relies on common sense, seeks satisfying solutions
Analytic Answer - Learns by analyzing, uses step by step procedure, values
quantitative and models, builds mathematical models, seeks optimal solution
Data extraction Answer - Extract data from primary/secondary source
Data transformation Answer - Transform/clean data into proper format or
structure for the purpose of querying and analysis
Data load Answer - Load data into final target database, more specifically as
operational data store, data mart or data warehouse
