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 PRO 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.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw PRO

Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior. Applying of SSADM is easy with ConceptDraw PRO diagramming and vector drawing software and Data Flow Diagram solution.

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 PRO 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 PRO. 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 PRO software.

UML Sample Project

Unified Modeling Language (UML) is a graphical modeling language for describing, visualizing, projecting and documenting of object oriented systems. UML digram is used for modeling of organizations and their business processes, for development the big projects, the complex software applications. Comprehensive UML diagram allows to create the set of interrelated documents that gives the complete visual representation of the modeling system.

Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ER Diagram, E-R Diagram, ERD) is a time-tested and widespread software development and software engineering method for data modeling, illustrating the logical structure of databases and system design. For ERDs construction are used three basic elements: entities, attributes, and relationships. Chen's notation for ERD supposes the use of rectangles (boxes) to represent entities and diamonds to depict relationships between first-class objects. This notation is popular when creating conceptual data models of information systems. Another standardized notation for ER diagrams is Crow's foot notation. ConceptDraw PRO as a powerful Entity Relationship Diagram software engineering provides the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park for instantly describing databases using ERDs of Crow’s Foot and Chen’s notations. Use the predesigned vector elements for both these notations from 2 libraries included to Entity-Relationship Diagram (ERD) solution.

Flow chart Example. Warehouse Flowchart

Warehouse Flowcharts are various diagrams that describe the warehousing and inventory management processes on the warehouses. Typical purposes of Warehouse Flowcharts are evaluating warehouse performance, measuring efficiency of customer service and organizational performance. This type of Workflow diagrams can be used for identifying any disconnection between business activities and business objectives. They are effectively used by warehouse-related people and organizations, manufacturers, wholesalers, exporters, importers, transporters, and others. Standard Warehousing process flow diagram and standard Workflow diagram are used for process identification for further evaluating effectiveness and profitability of overall business process. Use the ConceptDraw PRO vector graphic software extended with Flowcharts solution to design your own professional-looking Workflow diagrams and Flowcharts of any types, including the Warehouse flowchart, Process flow diagrams which depict in details all steps of Warehouse packages flow. Microsoft Visio, designed for Windows users, can’t be opened directly on Mac. But fortunately, there are several Visio alternatives for Mac which will help Mac users to work Visio files. With ConceptDraw PRO, you may open, edit and save files in Visio format.

Horizontal Orgchart

The Organizational Chart is a diagram that shows the structure of the organization and the relationships of its parts. There are many ways to present the Organizational Chart. One of them is the Horizontal Organizational Chart: the parts of the diagram are arranged from left to right, or from right to left. This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Organizational Charts Solution from the Management area of ConceptDraw Solution Park.

Horizontal Org Flow Chart

This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Organizational Charts Solution from the Management area of ConceptDraw Solution Park. The Organizational Chart is a diagram that shows the structure of the organization, different levels of management, hierarchy and the relationships of the organization parts.

Systems Engineering

Systems engineering is an interdisciplinary field of engineering that focuses on how to design and manage complex engineering systems over their life cycles. ConceptDraw PRO supplied with SysML Solution from the Software Development Area of ConceptDraw Solution Park is a powerful and effective systems engineering software.
