● Information systems design is defined as those tasks that focus on the specification of a detailed computer-based solution. Typically, there are four systems design tasks for in-house development.1) The first task is to specify （71） , which defines the technologies to be used by one, more, or all information systems in terms of their data, processes, interfaces, and network components. This task is accomplished by analyzing the data models and process models that are initially created during requirements analysis.2) The next systems design task is to develop the （72） . The purpose of this task is to prepare technical design specifications for a database that will be adaptable to future requirements and expansion.3) Once the database prototype has been built, the systems designer can work closely with system users to develop input, output and dialogue specifications. The （73） must be specified to ensure that the outputs are not lost, misrouted, misused, or incomplete.4) The fourth design task involves packaging all the specifications from the previous design tasks into a set of specifications that will guide the （74） activities during the following phases of the systems development methodology.Finally, we should （75） and update the project plan accordingly. The key deliverable should include a detailed plan for the construction phase that should follow.（71）A. an application architectureB. a distributed systemC. a system scopeD. a system physical model（72）A. database design specificationsB. database organization decisionsC. data structure specificationsD. data distribution decisions（73）A. format and layoutB. transaction detailsC. additional instructionsD. internal controls（74）A. system administrator’sB. system analyst’sC. computer programmer’sD. system designer’s（75）A. adjust the project scheduleB. reevaluate project feasibilityC. evaluate vendor proposalsD. select the best vendor proposal
