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.

Mesh Network Topology Diagram

A Mesh Network Topology is a computer network topology built on the principle of cells. The network workstations are the mesh nodes, they are connected to each other, usually to the principle "each with each" (a fully connected network) and interact in the distribution of data in a network. Each node relays the data for the network and can take the role of switch for other participants. Mesh Network Topology is sufficiently complex to configure, but however it provides a high fault tolerance, has a capability for self-healing and is considered as quite reliable. Large number of nodes' connections assures a wide selection of route of following the traffic within a network, therefore the breaking of one connection will not disrupt the functioning of network as a whole. As a rule, the Mesh Networks are wireless. The Mesh Network Topology Diagrams of any complexity and Wireless Mesh Network Diagrams are easy for construction in ConceptDraw DIAGRAM diagramming and vector drawing software using the tools of Computer Network Diagrams solution from Computer and Networks area.

Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams

ER-model is a data model which lets describe the conceptual schemes in a specific subject area. It can help to highlight the key entities and specify relationships that can be established between these entities. During the database design, it is realized the transformation of ER model into certain database scheme based on the chosen data model (relational, object, network, etc.). There are used two notations for ERDs: Crow's Foot and Chen's. Crow's Foot notation proposed by Gordon Everest represents the entity by rectangle containing its name (name must be unique within this model), and relation - by the line which links two entities involved in relationship. The relationship's plurality is graphically indicated by a "plug" on the end of the link, the optionality - by a circle. Entity-Relationship Diagrams based on Crow's Foot notation can be easily drawn using the ConceptDraw DIAGRAM. Extended with Entity-Relationship Diagram (ERD) solution, it is the best ERD diagrams software with powerful tools and ready design elements for Crow's Foot and Chen notations.
