Example of DFD for Online Store (Data Flow Diagram) DFD Example

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw DIAGRAM enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols.

UML Diagram for System

This sample shows the UML Class Diagram of delivery system. On this diagram you can see the classes that are connected with aggregation and composition associations indicated with the multiplicity. This sample can be used by delivery services, postal services.

UML Tool & UML Diagram Examples

The Unified Modeling Language (abbr. UML) is a general-purpose modeling language widely used in the field of software development, software engineering, education, science, industry, business. In 1997 the UML was approved as a standard by the OMG (Object Management Group) and in 2005 was published as ISO standard by the International Organization for Standardization. UML is widely and succesfully applied for optimization the process of software systems development and business systems analysis. There are used 14 types of UML diagrams, 7 from them depict structural information, another 7 types represent different types of behavior and aspects of interactions. Design of any automated process is easy with ConceptDraw DIAGRAM and unique Rapid UML solution from the Software Development area, which provides numerous UML examples, templates and vector stencils libraries for drawing all types of UML 1.x and UML 2.x diagrams. Use of predesigned UML diagram examples and templates lets you quickly start drawing your own UML diagrams in ConceptDraw DIAGRAM software.

Design Data Flow. DFD Library

Data flow diagram or DFD is a type of diagrams used for graphical representation the "flow" of data through an information system, for effective modeling its process aspects and for visualization the data processing. They are one of the best tools for clearly making an overview of the system that will be developed, for depiction in details what kinds of information will be inputted to the system and outputted from it, where they will be stored, and other details. ConceptDraw DIAGRAM software with Data Flow Diagrams solution from Software Development area of ConceptDraw Solution Park is powerful in a field of designing the DFDs. Three libraries containing 49 vector DFD shapes and symbols are offered by Data Flow Diagrams (DFD) solution. Use them to design data flow diagrams, information flow diagrams, data flowcharts, data process diagrams, structured analysis diagrams, to create the data-oriented models or process-oriented models, and so on. Pay also attention for the included collection of DFD samples, examples and built-in templates at ConceptDraw STORE.

Flowchart Components

The ConceptDraw Flowchart component includes a set of samples and templates. This geathered as flowchart maker toolbox which focused on drawing flowcharts of any industry standards.

This sample shows the work of the taxi service and is used by taxi stations, by airports, in the tourism field and delivery service.

ConceptDraw DIAGRAM ER Diagram Tool

Entity-relationship model, also called ER-model, is the main tool of domain modeling on the stage of conceptual design. The modeling of domain data structures is based on the use of graphical tools - Entity-Relationship diagrams (ER-diagrams). The core concepts of ER-Diagram are entity, attribute and relationship. ER-diagram lets visually represent the entities, helps effectively document all properties of designed system and to detail the data storages. To represent the elements at ER-model are commonly used Chen’s notation and Crow’s foot notation, each has its pros and cons. The entity on ER-diagram is represented in the form of rectangle, which specifies its name. An attribute is a property of the entity and relationship is an interaction between the entities. The relationship between two entities is called binary, between more than two entities - ternary. Specific software, such as ConceptDraw DIAGRAM with Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park is helpful for easy creation Entity-Relationship Diagrams.
