Entity-Relationship Diagram (ERD) is applied for detailed description of structures and high-level (conceptual) design databases using the Chen's and Crow's Foot notations. An ERD represents a diagram constructed mainly of rectangular blocks (for entities, data) linked with relationships. The links between the blocks are used to describe relations between the entities. There are three types of relationships: one-to-one, one-to-many, and many-to-many.
Use the specialized ERD software - ConceptDraw PRO to create the Entity-Relationship Diagrams (ERDs) of any degree of complexity with Chen's and Crow's Foot notations. Draw them easily applying the powerful built-in tools and libraries of predesigned ERD vector objects from Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park. You can also start with one of ready template or sample included to this solution. Designing the ERDs in ConceptDraw PRO you can easy move the objects within a diagram with saving the relationships between them.
The vector stencils library Crow's Foot Notation from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Crow's foot notation such as relationship symbols and entity symbols for ConceptDraw PRO diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.
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 PRO. 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.
Activity diagram describes the business and operational step-by-step workflows of components in a system. An activity diagram shows the overall flow of control.
The problem solving and decision-making processes are closely linked and crucial for the business and life. There are many tools and techniques for facilitating and improvement these processes, and also enhancement the quality of accepted decisions. One of them is Fisbone Diagram or Cause and Effect diagram. For its construction, you need first define the problem which you need to solve (existing or potential), write it into rectangular and draw to it a horizontal line - a “fish spine”. Then define general types of possible causes like Persons, Materials, Methods, Machinery, Measurements or Environment, and attach them to “spine”. Start brainstorming the possible reasons of failure and connect them to the branches.
Professional diagramming ConceptDraw PRO MAC OSX software offers the Fishbone Diagrams solution which contains templates, samples, and ready Fishbone design objects. Use of them lets effectively identify the possible causes for an effect, realize successfully cause and effect analysis, and instantly draw Fishbone diagram on Mac software.
A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design.
The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations.
ConceptDraw software has been developed for drawing any type of flowchart. Use RapidDraw - thi is flowchart maker technology for adding new objects to a flowchart quickly.
