Seminar: Bolt-ons

  1. 1. Hour 7: Business Intelligence & ERP ERP offers opportunity to store vast volumes of data This data can be data mined Customer Relationship Management
  2. 2. Data Storage Systems <ul><li>Data Warehousing </li></ul><ul><ul><li>Orderly & accessible repository of known facts & related data </li></ul></ul><ul><ul><li>Subject-oriented, integrated, time-variant, non-volatile </li></ul></ul><ul><ul><li>Massive data storage </li></ul></ul><ul><ul><li>Efficient data retrieval </li></ul></ul><ul><li>CRM one data mining application </li></ul><ul><ul><li>Can use all of this data </li></ul></ul><ul><ul><li>Common ERP add-on </li></ul></ul>
  3. 3. Granularity <ul><li>Definition – level of detail </li></ul><ul><ul><li>Most granular – each transaction stored </li></ul></ul><ul><ul><li>Averaging & aggregation loses granularity </li></ul></ul><ul><li>Data warehouses usually store data at fine levels of granularity </li></ul><ul><ul><li>You can’t undo averages & aggregates </li></ul></ul>
