  13. The Previous Queries Generate Reports and Answer Aggregate Questions (BI) • Relate to decision making more than business operations • Aggregate customers, contracts, deals, services… • Not necessarily “Real time” • Mostly Selects • “Large” amount of data • Small number of “large”, “complex” queries

  15. Analytics is more sophisticated analysis (typically non-SQL) • Questions relate to decision making, more than business operations • SQL provides the input, but is not sufficient. Require additional software (SPSS, SAS, R, Data miner…) • More similar to BI queries than operational queries.

  16. BI and Analytics Queries Slow Down the Systems that Run our Businesses • Idea: create a copy of the data and perform analysis on it • The DB that contains this offline data is called a Data Warehouse (aka data mart, data hub…)
