Basic Flowchart Symbols and Meaning

Flowcharts are the best for visually representation the business processes and the flow of a custom-order process through various departments within an organization. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Flowcharts solution offers the full set of predesigned basic flowchart symbols which are gathered at two libraries: Flowchart and Flowcharts Rapid Draw. Among them are: process, terminator, decision, data, document, display, manual loop, and many other specific symbols. The meaning for each symbol offered by ConceptDraw gives the presentation about their proposed use in professional Flowcharts for business and technical processes, software algorithms, well-developed structures of web sites, Workflow diagrams, Process flow diagram and correlation in developing on-line instructional projects or business process system. Use of ready flow chart symbols in diagrams is incredibly useful - you need simply drag desired from the libraries to your document and arrange them in required order. There are a few serious alternatives to Visio for Mac, one of them is ConceptDraw DIAGRAM. It is one of the main contender with the most similar features and capabilities.

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.

Data Flow Diagram Example

ConceptDraw DIAGRAM extended with Data Flow Diagrams solution is the best diagramming and vector drawing software for quick and easy designing the Data Flow Diagram Example of any complexity.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams graphically represent the information transfers and process steps of a system. They visually depict how data are processed by a system in terms of inputs and outputs, how occurs the input in a system, how the data flow through an information system and where they are stored, and how occurs output from the system. DFDs give the overview of the system and models the processes aspects, they are maintained with other methods of structured systems analysis. The main goal of DFDs is achievement of understanding between developers and users. For their construction are used two notations - Gane-Sarson and Yourdon, each of them uses its own set of symbols. Data Flow Diagrams solution from Software Development area extends the ConceptDraw DIAGRAM software with templates, samples, and predesigned libraries of data flow diagram symbols for both notations, allowing you easy design the process-oriented and data-oriented models, draw the Data Flow Diagrams, Data Flowcharts, Data Process Diagrams, Information Flow Diagrams, Structured Analysis Diagrams, etc.

Tree Network Topology Diagram

A Tree network topology (Hierarchical topology) is a hybrid network topology that contains the combination of two or more star networks connected via bus networks. Each star network is a LAN (local area network) with central computer or server and workstation nodes connected to it. The central computers of star networks are connected to a main cable that is called a bus. Each node of the Tree network can have an arbitrary number of child nodes, you can easy add/remove the separate workstations and even the whole star networks, the failure of one workstation will not affect the work of others. This topology is ideal solution when workstations are located in groups within a small physical region, rarely is used in WAN configurations. Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park contains templates, samples and numerous libraries of predesigned vector stencils of computer network devices and equipment, which can be effectively used for designing various network topologies diagrams, including Tree Network Topology.

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.

Ring Network Topology

The Ring Network Topology Diagram examples was created using ConceptDraw DIAGRAM software with Computer and Networks solution.

ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.

How To Create Onion Diagram

An onion diagram is a kind of chart that shows the dependencies among parts of an organization or process. The chart displays items in concentric circles, where the items in each ring depend on the items in the smaller rings. The Onion Diagram is able to show layers of a complete system in a few circles. But how to create Onion Diagram? Now, it's very easy thanks to the ConceptDraw DIAGRAM diagramming and vector drawing software extended with Stakeholder Onion Diagrams Solution from the Management Area of ConceptDraw Solution Park.

Circle Diagrams

The Circle Diagrams are the diagrams which represent the central element surrounded by other items in a circle. This type of diagram is very popular and widely used in marketing and management, for process modeling, market, resource, time and cost analysis, for visualization causes and effects. If you dream to design the Circle Diagrams quick and easy – the ConceptDraw DIAGRAM software extended with Circle-Spoke Diagrams Solution from the "Diagrams" Area is exactly what you need.
