Example of DFD for Online Store (Data Flow Diagram) DFD Example
Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

The ConceptDraw Flowchart component includes a set of samples and templates. This geathered as flowchart maker toolbox which focused on drawing flowcharts of any industry standards.Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams
Crow's Foot notation was proposed by Gordon Everest. According to this notation, the entity is represented by rectangle, relation is depicted by line which ties two entities involved in a relationship. Entity-relationship diagrams based on both Chen's and Crow's Foot notations, can be easily drawn using the ConceptDraw PRO ERD diagrams software tools for design element Crow's Foot and Chen from Entity-Relationship Diagram (ERD) solution.Entity-Relationship Diagram (ERD) with ConceptDraw PRO
Entity-Relationship Diagram (ERD) serves for detailed description of structures and databases. An ERD represents a diagram made up mainly of rectangular blocks (for entities, or data) linked with relationships. The links between the blocks describe relations between these entities. There are three types of relationships: one-to-one,one-to-many, many-to-many.
Draw Entity-Relationship Diagrams (ERD) easily with ConceptDraw extended with Entity-Relationship Diagram (ERD) Solution from the Software Development Area. Use ERD software to create ER diagram.
Entity Relationship Diagram - ERD - Software for Design Chen ER Diagrams
The Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park extends ConceptDraw PRO vector graphics and diagramming software with the ability to describe a database using the Entity-Relationship (Chen) model. Use it for design your ERDs and verify that ConceptDraw PRO offers the best ERD diagrams software tools for design element Chen notation.Chen ERD Diagram
The vector stencils library Chen ERD from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Chen ERD notation including entity symbols and relationship 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.Process Flowchart
ConceptDraw is Professional business process mapping software for making process flow diagram, workflow diagram, general flowcharts and technical illustrations for business documents. It is includes rich examples, templates, process flowchart symbols. ConceptDraw flowchart maker allows you to easier create a process flowchart. Use a variety of drawing tools, smart connectors, flowchart symbols and shape libraries to create flowcharts of complex processes, process flow diagrams, procedures and information exchange.Entity-Relationship Diagram (ERD)
An Entity-Relationship Diagram (ERD) is a visual presentation of entities and relationships. That type of diagrams is often used in the semi-structured or unstructured data in databases and information systems. At first glance ERD is similar to a flowch
Program Evaluation and Review Technique (PERT) with ConceptDraw PRO
PERT Diagram is a more realistic approach of a project's time estimate analysis. After PERT chart was constructed user can discover the shortest possible duration for entire project timescale. The project timeline is the longest chain that might be taken with connected tasks on the PERT Diagram. Completion of serial tasks need to be accomplished in a presented order. At a project timeline can be independent tasks that not linked with main sequence they are called parallel tasks. PERT diagram is more suitable for Critical Path Analysis than Gantt chart for the reason that it undoubtedly better determine task dependencies. Project managers customarily utilize both methodologies.Entity Relationship Software
Entity Relationship Diagrams (ERD) illustrate the logical structure of databases.The vector graphic diagrams produced when using the ConceptDraw ERD solution can be used in whitepapers, presentations, datasheets, posters, or any technical materials.
It is convenient to design ER Diagrams using ConceptDraw PRO software. ConceptDraw PRO extended with the Entity-Relationship Diagram (ERD) solution supports Chen's and Crow’s Foot notations that are often used to describe database structure.
