DeVry HIT120 Week 4 Discussion 1 & 2 Latest 2016 November
dq 1Healthcare Information Systems & Their Development (graded)General Hospital has determined that within three years, it will replace the nurses’ paper documentation with an electronic system. Nurses will use the new system to document progress notes on the patient, vital signs, and any other nursing care activities. The new system needs to communicate with the patient registration, admission, discharge, and transfer system (R-ADT) as well as support the clinical decision support system (CDSS). General Hospital is in the process of creating a committee in order to start the process of analysis and defining the requirements of the system. The committee will follow the process of the systems development life cycle (SDLC). You have been appointed to this committee and before giving your contribution to this project, need to understand and explain the information systems and the Systems Development Life Cycle. Describe different types of systems being discussed and explain the category they fit in (operations support, enterprise-wide, or management support information system). Identify the SDLC phases and provide a thorough description of each phase, including basic activities that occur in each phase.dq 2Databases & Other Information Systems Components (graded)After studying Sayles, pages 879-887, explain what is a database and what is it used for?
