Example of DFD for Online Store (Data Flow Diagram)

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 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.

UML Component Diagram

UML Component Diagrams are used to illustrate the structure of arbitrarily complex systems and illustrates the service consumer - service provider relationship between components.

UML Class Diagrams. Diagramming Software for Design UML Diagrams

In software engineering, a UML Class Diagrams is a type of static structure diagram that is used both for general conceptual modeling of the systematics of the application, and for detailed modeling translating the models into programming code. Use ConceptDraw DIAGRAM with UML class diagram templates, samples and stencil library from Rapid UML solution to show the classes of system, their attributes, operations or methods, and the relationships among the classes.

UML Collaboration Diagram (UML2.0)

UML Collaboration Diagram depicts the interactions between objects or parts in terms of sequenced messages and describes both the static structure and dynamic behavior of a system. Rapid UML solution provides templates, examples and libraries of stencils for quick and easy drawing all the types of system and software engineering diagrams according to UML 2.4 and 1.2 notations.

Data Flow Diagrams

Data Flow Diagram (DFD) is a special chart type which lets graphically illustrate the "flow" of data through an information system. So the Data Flow Diagrams can be successfully used for visualization of data processing or structured design, for creation an overview of the system, for business process modeling, for exploring the high-level design in terms of data flows and documenting the major data flows. Inclusion of powerful Data Flow Diagrams solution to the Software Development area of ConceptDraw Solution Park makes the ConceptDraw DIAGRAM a beneficial data flow diagramming software and supplies it with numerous collection of quick-start templates, professionaly designed samples, and extensive range of ready-for-use vector objects consisting the Data Flow Diagrams, Gane-Sarson Notation, and Yourdon and Coad Notation libraries. Use the ConceptDraw DIAGRAM application to design easy and quickly the Data Flow Diagrams including the data storages, data flows, external entities, functional transforms, control transforms and signals.

Gane Sarson Diagram

The Gane-Sarson methodology uses the graphical techniques for building the logical models for the systems. It is helpful for analysts and designers to make common and clear picture of the system, to depict all its processes and how they transform the data. The Gane-Sarson methodology lets represent all this information in a way understandable for the users and other interested people, and gives the possibility to see instantly how the system's parts serve together to meet their needs. This methodology supposes the building of a system top-down. First you need create an overall system data flow, then determine the details of the data structures, the process logic and design the modular structures. ConceptDraw DIAGRAM diagramming and vector drawing software offers the Data Flow Diagrams solution with Gane-Sarson Notation library rich for the specific symbols of the Gane-Sarson notation. All they are vector and fully ready-to-use for drawing the Data Flow Diagrams, which will be then successfully used in presentations, websites, and various business documents.

Structured Systems Analysis and Design Method. SSADM with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior. Applying of SSADM is easy with ConceptDraw DIAGRAM diagramming and vector drawing software and Data Flow Diagram solution.

Entity Relationship Diagram Symbols

The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style. The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software.
