Entity Relationship Diagram Symbols

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM.

Technical Flow Chart

Flow chart is a diagrammatic representation of an algorithm and essential part of planning the system. Flow charts are widely used in technical analysis and programming for easy writing programs and explaining them to others. So, one of the most popular type of flow charts is Technical Flow Chart.
Technical Flow Chart can be drawn by pencil on the paper, but it will be easier to use for designing a special software. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Flowcharts Solution from the "Diagrams" Area of ConceptDraw Solution Park will be useful for this goal.

Data Flow Diagram

Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

How to Create an Entity-Relationship Diagram Using ERD Solution

An entity-relationship diagram (ERD)is used in a database modeling process. ERD diagram shows a graphical representation of objects or concepts within an information system and their relationships. The ability to describe a database using the Entity-Relationship model is delivered by the ConceptDraw ERD solution.

Yourdon and Coad Diagram

The vector stencils library Yourdon and Coad Notation from the solution OOAD contains specific symbols of the Yourdon and Coad notation such as data store symbol, data process symbol, loop symbol for ConceptDraw DIAGRAM diagramming and vector drawing software. The OOAD solution is contained in the Software Development area of ConceptDraw Solution Park.
The business processes modeling (BPM) flowchart sample "Event-driven process chain (EPC) diagram" was created on the base of illustration from "Methods for the specification and verification of business processes. 19 - Event-driven process chains. Roberto Bruni. 2011".
"An Event-driven Process Chain (EPC) is a
particular type of flow-chart that can be used for configuring an Enterprise Resource Planning (ERP) implementation.
Supported by many tools (e.g. SAP R/ 3).
EPC Markup Language available (EPML)
as interchange format. ...
EPC overview.
Important notation to model the domain aspects of business processes.
Rather informal notation.
EPC focus is on representing domain concepts and processes (not their formal aspects and technical realization).
It can be used to drive the modeling, analysis and redesign of business process." [cli.di.unipi.it/ ~rbruni/ MPB-12/ 19-EPC.pdf]
The event-driven process chain (EPC) diagram example was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Event-driven Process Chain Diagrams solution from the Business Processes area of ConceptDraw Solution Park.
