SOLVED

51) Informational systems are designed to support decision making based on historical point-in-time and prediction data. 52) A separate data warehouse causes more contention for resources in an organization. 53) An independent data mart is filled with data extracted from the operational environment without the benefit of a data warehouse. 54) A data mart is a data warehouse that contains data that can be used across the entire organization. 55) Organizations adopt data mart architectures because it is easier to have separate, small data warehouses than to get all organizational parties to agree to one view of the organization in a central data warehouse. 56) Independent data marts do not generally lead to redundant data and efforts. 57) An enterprise data warehouse is the control point and single source of all data made available to end users for decision support applications. 58) A dependent data mart is filled from the enterprise data warehouse and its reconciled data. 59) An operational data store (ODS) is not designed for use by operational users. 60) An operational data store is typically a relational database and normalized, but it is tuned for decision-making applications.
