Document Summary

General: data is facts and figures in raw form, most organizations group their major business events into two processes: the order-to-cash process and the purchase-to-pay process. In a logical dataflow diagram, bubble symbols represent processes. While in a physical dataflow diagram, they represent entities. In the oe/s process, a document called a customer acknowledgment is sent to notify the customer of the order"s acceptance and the expected shipment date. In the hr management process, departmental managers and supervisors use hr forms for selecting employees, terminating employees and evaluating employees. Increased labour and inconsistencies in the data are consequences of data redundancy. There are two approaches to business event processing: application approach and centralized database approach. In the centralized database approach to business event processing, facts about events are stored in relational database tables instead of separate files. Types of dbms models: hierarchical, network and relational. In a hierarchical dbms, a child record can"t have more than one parent record.
