Using Data Flow Diagrams Data flow diagram is used by system analyst to put together a graphical representation of data processes throughout the organization. It depicts the broadest possible overview of system inputs‚ processes‚ and outputs. A series of layered data flow diagrams may be used to represent and analyze detailed procedures in the larger system. By using combinations of only four symbols‚ the system analyst can create a pictorial depiction of processes that will eventually provide

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

Week 1-Discussion 1-Circular Flow Diagram To first explain how the circular flow diagram relates to the current economic situation‚ one must realize that the two‚ three‚ and four sector models no longer apply to the United States any more. Only the five sector model currently applies. The five sector model of the circular flow of income is a more realistic representation of the economy and has a more definitive look as to what and how economics really is in the world. In the more simplistic two

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

DATA FLOW DIAGRAM Group#7 Nugao Oserin Obongen 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

7.7.4 Activity Diagram The progressions of an action chart are operations‚ particularly exercises from the state model. The motivation behind an action chart is to demonstrate the progressions inside an intricate procedure and the sequencing requirements among them. A few exercises run perpetually until an outside occasion interferes with them‚ yet most exercises inevitably finish their work and end themselves [7]. The finishing of a movement is a fruition occasion and normally demonstrates that
