The Data Flow Diagram (DFD)
• a graphical representation of the flow of data through an information system. It enables you to represent the processes in your information system from the viewpoint of data. The DFD lets you visualize how the system operates, what the system accomplishes and how it will be implemented, when it is refined with further specification.
• Data flow diagrams are used by systems analysts to design information-processing systems but also as a way to model whole organizations. You build a DFD at the very beginning of your business process modeling in order to model the functions your system has to carry out and the interaction between those functions together with focusing on data exchanges between processes. You can associate data with conceptual, logical, and physical data models and object-oriented models.

    Nt1310 Unit 4 Student Information System

    The rules help in shaping and providing the best database program that the college will use. One of the business rules is that the database will only be accessed by the database administrator or the heads of department. This way, students and instructors will not be able to alter any information without seeking for permission first. Results from the database will also be trusted because they are based on true facts that have taken place thought the course (Halpin& Morgan, 2008). The second rule is that all entities should understand their roles in the college. Departments will be responsible for offering courses. Classes will be generated based on the course. Instructors will be expected to teach the students in class. The students will be expected to learn from the instructor and perform well. Once all entities have known their roles, it will be easy to maintain and work with the database. Everybody will be expected to play their part to ensure that the college produces good…

    Describe the Application Architecture and Process Design

    Hugh McCauley Chief Operating Officer at Riordan Manufacturing would like a more sophisticated, state-of-the art, information systems technology in the Human Resources department. The current Riordan Manufacturing Human Resources Information System is attenuated and spreads resources out over several non-integrated systems. SR-rm-004 calls for the analyst of the HRIS and the recommendation to integrate the existing variety of tools in use today into a single integrated application. According Symphony Employer Service (2013), an integrated HRIS “gives you the ability to track and report on vital employee personal information, performance reviews, benefits, skills, injury occurrences and much more. Payroll and HR share one common database, eliminating duplicate entry and the need for customized imports.” Having the entire HRIS in a single integrated application will also reduce cost and time spent on manual data consolidation. It will also allow the stakeholders to focus more time on production since less HR paperwork will be generated.…

    The term system means the consistent arrangement of things connected to unity or to operate as a whole (Dictionary, 2012). In Systems theory we will describe dynamics in a family as dyads, triads, and in homeostasis. In a system when one part of that system changes, the whole system changes. Within a family system viewed as a whole there are similar smaller systems known as subsystems. Marital (couples), siblings; which are viewed as dyads, parents and child; viewed as triads, and homeostasis baseline behavior of a family. “A family is greater than the sum of its parts” (Phoenix, 2009).…

    Dependencies and Network Diagram

    The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks, except the first and the last, are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start (FS- the second task ‘successor’ can’t begin until the first ’predecessor’ is completed), Finish-to-finish (FF- the completion of the successor depends on the completion of its predecessor), Start-to-start (SS- the start of the successor depends on the start of its predecessor), Start-to-finish (SF- the finish of the successor depends on the start of its predecessor).…
