Data Flow Diagram

Data Flow Diagram (DFD) is the part of the Structured Systems Analysis and Design Methodology (SSADM), which is intended for information systems projection and analysis. Data Flow Diagrams allow graphically represent the data flows in information system and analyze the data processing during the structural projection. This type of diagrams lets visually show a work of information system and results of this work, it is often used in connection with human processes and can be displayed as Workflow diagram. Data Flow Diagram visualizes processes and functions, external entities, data depositories, and data flows connecting these elements and indicating direction and data character. Each of these elements used for DFD has its own graphical notation. There are two notations to draw DFDs - Yourdon & Coad and Gane & Sarson. ConceptDraw DIAGRAM extended with Data Flow Diagrams (DFD) solution from Software Developmant area is ideal for designing professional looking DFDs, which can be then easily exported in various formats.

ORM Diagram

The vector stencils library ORM Diagrams from the solution Software Development contains specific ORM symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Software Development solution is contained in the ConceptDraw Solution Park.

Functional Flow Block Diagram

You need to draw a Functional Flow Block Diagram? You are an artist? Now it doesn't matter. With Block Diagrams solution from the "Diagrams" area for ConceptDraw Solution Park you don't need more to be an artist to design the Functional Flow Block Diagram of any complexity.

Workflow Diagram Software Mac

ConceptDraw DIAGRAM software is the best Mac software for drawing workflow diagrams. Its rich set of samples and templates, and specific features to draw diagrams faster make this software as comfortable as possible for drawing workflow diagrams. Use the ConceptDraw DIAGRAM professional Mac OS X software for drawing workflow diagram. The Workflow Diagrams solution with its libraries and templates set make the possibility to identify resources that are required for work goal implementation. The process flow diagram identify flow which occurs as network of process dependencies, organizational decisions and interactions between departments. Usually workflow diagrams show business participants actions that carry product or service to the final destination, the consumer.

Entity Relationship Diagram Examples

Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database. ConceptDraw DIAGRAM professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity.

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.

Design elements - Ports and Flows

The vector stencils library "Ports and Flows" contains 26 SysML symbols.
Use it to design your SysML diagrams using ConceptDraw PRO diagramming and vector drawing software.
"The main motivation for specifying ports and flows is to enable design of modular, reusable blocks with clearly defined
ways of connecting and interacting with their context of use. This clause extends UML ports to support nested ports, and
extends blocks to support flow properties, and required and provided features, including blocks that type ports. Ports can be typed by blocks that support operations, receptions, and properties as in UML. SysML defines a specialized form of Block (InterfaceBlock) that can be used to support nested ports. SysML identifies two kinds of ports, one that exposes
features of the owning block or its internal parts (proxy ports), and another that supports its own features (full ports). Default compatibility rules are defined for connecting blocks used in composite structure, including parts and ports, with association blocks available to define more specific ways of doing this. These additional capabilities in SysML enable modelers to specify a wide variety of interconnectable components, which can be implemented through many engineering and social techniques, such as software, electrical or mechanical components, and human organizations. This clause also extends UML information flows for specifying item flows across connectors and associations." [www.omg.org/ spec/ SysML/ 1.3/ PDF]
The SysML shapes example "Design elements - Ports and Flows" is included in the SysML solution from the Software Development area of ConceptDraw Solution Park.
