3Drawn using certain special-purpose symbols. How to determine the flow of data through a network and identify process logic?What is a flowchart?Is a graphical representation of an algorithm or of a portion an algorithm.Drawn using certain special-purpose symbols.RectanglesDiamondsOvalsSmall CirclesThese symbols are connected by arrows called flowlines.
4Symbols Rectangle Also called action symbol Indicates any type of action including a calculation or an input/output operationAdd 10 to Grade
5Flowlines (Arrows)Indicate the order in which the actions are to be performed.
8Diamond Also called the decision symbol Indicates a decision is to be madeNOGrade < = 59Yes
9Input/OutputRepresents data that is available for input or resulting from processing.
10Example of a Flowchart Start No Yes Print Pass Stop Enter Grade Print FailedPrint PassStop
11How to describe the system development cycle? The system development life cycle (SDLC) refers to the structure and stages used in the software development process from initial product conception through to product development and follow up maintenance.
13Let’s practice! Take out a sheet of paper. Write your answers to the following sample questions.
14Sample Questions A typical non-functional user requirement is/are A. What the user interface looks likeB. The user’s constraints and purposesC. the resources needed to maintain the systemD. The actions the system performs automatically
15The following programming flowchart symbol is a/an _______. ProcessingInput/outputDecisionconnector
16One of the main goals in analyzing user requirements is to Troubleshoot the problemShutdown and maintain the systemKeep the customer happyElicit requirements from a user’s point of view
17Which of the following flowchart symbols indicates a question or branch in the process flow? ConnectorDecisionProcessExtract
18If a record has the following field lengths, what is the record length? Name=35, Zipcode=5, District =742475456
19The implementation phase consists of coding, testing, and DesigningBuilding prototype programsEstablishing requirementsIntegration
