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.

Program Evaluation and Review Technique (PERT) with ConceptDraw PRO

Program Evaluation and Review Technique (abbr. PERT) is a method developed by Ministry of Defense of the USA in 1958 for the project of creation the missile system Polaris. PERT diagram is one of the tools for project management that lets greatly simplify the planning and scheduling of large and complex projects. PERT diagram provides evaluation of project run-time and labor forces, it helps to analyze the time necessary for execution each of project tasks and the whole project, and to calculate the project critical path. PERT chart depicts the set of tasks connected each other in order of their execution and is constructed according to one of definite rules - AOA (activity on arrow) or AON (activity on node). It doesn't give you ready concrete decisions, but helps to find them. Design easy the PERT diagrams in ConceptDraw PRO software enhanced with Seven Management and Planning Tools solution from Management area of ConceptDraw Solution Park. You have a possibility to build the PERT chart of any type, but AON variant is easier for building and perception. Read more

Data Flow Diagrams

Data Flow Diagram (DFD) is a special chart type which lets graphically illustrate the "flow" of data through an information system. So the Data Flow Diagrams can be successfully used for visualization of data processing or structured design, for creation an overview of the system, for business process modeling, for exploring the high-level design in terms of data flows and documenting the major data flows. Inclusion of powerful Data Flow Diagrams solution to the Software Development area of ConceptDraw Solution Park makes the ConceptDraw PRO a beneficial data flow diagramming software and supplies it with numerous collection of quick-start templates, professionaly designed samples, and extensive range of ready-for-use vector objects consisting the Data Flow Diagrams, Gane-Sarson Notation, and Yourdon and Coad Notation libraries. Use the ConceptDraw PRO application to design easy and quickly the Data Flow Diagrams including the data storages, data flows, external entities, functional transforms, control transforms and signals.

Example of DFD for Online Store (Data Flow Diagram) DFD Example

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 PRO 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. Read more

Developing Entity Relationship Diagrams

When you need to visually represent the structure of relational database, Entity relationship diagram (ERD) is a type of diagram for that case. Most entity-relationship diagrams can be built with objects from Flowchart solution or ERD Solution which contains inbuilt templates. Follow these steps to create your own custom ERD diagram. Don't be frightened if it looks complex, ConceptDraw PRO makes it easy to create an ERD, and hundreds of other diagrams, in minutes. Read more

Data Flow Diagrams

The information system manages the flow of data introduced into the system. To graphically represent and document the flow of data through some information system is used a Data Flow Diagram (DFD). DFD is a way to visualize the flow of data or data processing, to clearly demonstrate what type of data or information is transferred, where they come from and where are sent. It lets to create an overview of the system, to depict the major steps, and effectively model the processes. DFDs are helpful for analyzing and modifying the business systems. Traditionally are used two notations for DFDs creation - Yourdon-Coad and Gane-Sarson. ConceptDraw PRO software offers a special Data Flow Diagrams solution from Software Development area, which enables to quickly and simply create professional Data Flow Diagrams including the data storage, data flows, external entities, functional transforms, control transforms and signals. Use the offered templates, samples and extensive range of libraries to design your own Data Flow Diagrams in minutes. Read more

Process Flowchart

The main reason of using Process Flowchart or PFD is to show relations between major parts of the system. Process Flowcharts are used in process engineering and chemical industry where there is a requirement of depicting relationships between major components only and not include minor parts. Process Flowcharts for single unit or multiple units differ in their structure and implementation. ConceptDraw PRO is Professional business process mapping software for making Process flowcharts, Process flow diagram, Workflow diagram, flowcharts and technical illustrations for business documents and also comprehensive visio for mac application. Easier define and document basic work and data flows, financial, production and quality management processes to increase efficiency of your business with ConcepDraw PRO. Business process mapping software with Flowchart Maker ConceptDraw PRO includes extensive drawing tools, rich examples and templates, process flowchart symbols and shape libraries, smart connectors that allow you create the flowcharts of complex processes, process flow diagrams, procedures and information exchange. Process Flowchart Solution is project management workflow tools which is part ConceptDraw Project marketing project management software. Drawing charts, diagrams, and network layouts has long been the monopoly of Microsoft Visio, making Mac users to struggle when needing such visio alternative like visio for mac, it requires only to view features, make a minor edit to, or print a diagram or chart. Thankfully to MS Visio alternative like ConceptDraw PRO software, this is cross-platform charting and business process management tool, now visio alternative for making sort of visio diagram is not a problem anymore however many people still name it business process visio tools.
