Data Modeling with Entity Relationship Diagram
Data modeling is actively applied in analysis and uses wide set of methods for description the data requirements in a system. One of the most popular and well-known is the ERD method of database modeling. The best ERD tool for the Mac and Windows is ConceptDraw DIAGRAM software extended with the Entity-Relationship Diagram (ERD) solution from the Software Development Area for ConceptDraw Solution Park, which is sharpened for professional ERD drawing and data modeling with Entity Relationship Diagram.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.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.Campus Area Networks (CAN). Computer and Network Examples
Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.UML Class Diagram Notation
When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system. The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them.Fishbone Diagram Design Element
