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 but

Executive Summary Overview The purpose of the Stonebrook Resort Survey Project (SRSP) is to improve the current guest satisfaction survey process. The scope of the project is to improve the way the guest survey responses are captured‚ stored and tracked. Additionally‚ it will help the Marketing department identify “happy” guests in order to provide these guests with resort promotions. The purposed solution is to install the Survey Management Application (SMA) on hotel computers. This program

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The direction of the arrow shows the direction that the force is acting. Each force arrow in the diagram is labeled

is a data flow diagram? Why do systems analysts use data flow diagrams? Answers: A picture of the movement of data between external entities and the processes and data stores within a system. Systems analysts use DFDs to help in the analysis phase by accomplishing the following three things: 1. Requirements Determination 2. Requirements Structuring 3. Alternative Generation and Selection 3. Explain the rules for drawing good data flow diagrams. Answers: Process: A. No process can have only outputs

Logic to Ladder Diagram There are some methods to do PLC programming. The programming methods can be with Logic Ladder Diagram‚ mnemonic (statement list)‚ and / or function block diagram. One of the PLC programming methods that are very commonly used programming using PLC ladder diagram. The method is practical and easy to understand. The programmer in charge of writing a program should describe an electronic switch circuit. It can be designed to perform the conversion of electronic circuits that

EDI Electronic Data Interchanges Electronic Data Interchanges technology is a complicated mixture of three disciplines: business‚ data processing and data communication. Integrated with logistics practices EDI can be defined as the electronic exchange of business data‚ such as purchase orders‚ invoices‚ and shipping notices‚ typically between one organization and another. The relationship is usually between a vendor and customer. EDI began in the 1970s and was first developed by the automobile

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but
