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

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

Study Inventory is basically the total amount of goods and materials held in stock by a factory‚ store and other business. An inventory system is a process whereby a business keeps track of the goods and material it has available. In its simplest sense it can be done manually by a count at the end of each day. In this way it is possible to keep a record of the goods coming in to the business and goods being sold. The same case applies in Kuya’s Lumpiang Sariwa and as a result‚ the inventory system

Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations
