                                    are  properly aligned (Hill, 2008). Following are the most common components of a
                                      business  reporting system.

                                       • OLTP (online transaction processing).  A system that measures some aspect
                                         of the real world as events (e.g., transactions) and records them into enterprise
                                         databases. Examples include ERP systems, POS systems, Web servers, RFID readers,
                                         handheld inventory readers, card readers, and so forth.
                                       • Data supply.  A system that takes recorded events/transactions and delivers them
                                         reliably to the reporting system. The data access can be push or pull, depending
                                         on whether or not it is responsible for initiating the delivery process. It can also be
                                         polled (or batched) if the data are transferred periodically, or triggered (or online)
                                         if data are transferred in case of a specific event.
                                       • ETL (extract, transform, and load).  This is the intermediate step where these
                                         recorded transactions/events are checked for quality, put into the appropriate
                                           format, and inserted into the desired data format.
                                       • Data storage.  This is the storage area for the data and metadata. It could be a
                                         flat file or a spreadsheet, but it is usually a relational database management system
                                         (RDBMS) set up as a data mart, data warehouse, or operational data store (ODS); it
                                         often employs online analytical processing (OLAP) functions like cubes.
                                       • Business logic.  The explicit steps for how the recorded transactions/events are
                                         to be converted into metrics, scorecards, and dashboards.
                                       • Publication.  The system that builds the various reports and hosts them (for
                                         users) or disseminates them (to users). These systems may also provide notification,
                                         annotation, collaboration, and other services.
                                       • Assurance.  A good business reporting system is expected to offer a quality
                                           service to its users. This includes determining if and when the right information is to
                                         be delivered to the right people in the right way/format.
                                         Application Case 4.2 is an excellent example to illustrate the power and the util-
                                    ity of automated report generation for a large (and, at a time of natural crisis, somewhat
                                    chaotic) organization like FEMA.





                  Application Case 4.2

                  Flood of Paper Ends at FEMA
                  Staff at the Federal Emergency Management Agency  project manager and computer scientist,  respectively,

                  national disaster, always got two floods at once.  Builders to turn back the flood of paper generated
                  First, water covered the land. Next, a flood of paper,  by the NFIP. The program allows the  government

                  Program (NFIP), covered their desks—pallets  to  collect flood insurance premiums and pay claims
