1. What is data vis-à-vis information? When can information be deemed good and useful? How are these related/ connected to an information system? Data are facts‚ which may or may not be processed (edited‚ summarized‚ or refined) and have no direct effect on the user. By contrast‚ information causes the user to take an action that he or she otherwise could not‚ or would not‚ have taken. Information is often defined simply as processed data. This is an inadequate definition. Information is determined

Structuring System Requirements: Process Modeling Problems and exercises Course project questions Diagram Outline This week‚ we learn how systems analysts collect material about information system requirements. Next‚ we will be introduced to process modeling and logic modeling. Although there are several methods and techniques available for process modeling‚ this week focuses on data-flow diagrams (DFDs). Please review the assignment tab and course project tab to understand the deliverables for

milestone you will prepare a Physical Data Flow Diagram. Physical data flow diagrams model the technical and human design decisions to be implemented as part of an information system. They communicate technical and other design constraints to those who will actually implement the system—in other words‚ they serve as a technical blueprint for the implementation. Objectives After completing this milestone‚ you should be able to: Draw physical data flow diagrams for an information system’s architecture

Software systems are divided into four major functions. Data storage in an Information System stores the data or file. Data Access Logic is managing needed to retrieve the data. Application Logic is the processes or activities that are executed. The final function is the Presentation Logic function which is the presentation of the information and the user interface. Knowledge of the functions is vital in the design process and the data flow diagrams (DFD). Architecture design begins with the non-practical

Developing DFDs: An Example To illustrate how DFDs are used to model the logic of data flows in information systems‚ we will present and work through an example. Consider Hoosier Burger‚ a fictional restaurant in Bloomington‚ Indiana‚ owned by Bob and Thelma Mellankamp. Some are convinced that its hamburgers are the best in Bloomington‚ maybe even in Southern Indiana. Many people‚ especially Indiana University students and faculty‚ frequently eat at Hoosier Burger. The restaurant uses an information

needed in order to formulate the most efficient means of transitioning to the upgraded application. Moreover‚ several different flows of data were discussed in a fairly general manner in regards to improving efficiency of the flow of said data. Efficiency of the software can be greatly increased in reducing the data flow footprint to provide the most efficient flow of data between departments.
