Document Summary
Lecture 10 designing inputs, outputs and controls nov 23. This chapter focuses on system interfaces, system outputs, and system controls that do not require much human interaction. Many system interfaces are electronic transmissions or paper outputs to external. System developers need to design and implement integrity and security controls to protect system and its data. Outside threats from internet and e-commerce are growing concern. Extension of html that embeds self-defined data structures in textual messages. Transaction that contains data fields can be sent with xml codes to define meaning of data fields. Xml is simple and readable by people. Web services is based on xml to send business transactions over internet. Identify devices and mechanisms used to enter input: high-level review of most up-to-date methods to enter data. Identify all system inputs and develop list of data content for each: provide link between design of application software and design of user and system interfaces.
