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.

Event-Driven Process Chain Diagram Software

It’s very easy, quick and convenient to draw the Event-driven Process Chain (EPC) diagrams in ConceptDraw DIAGRAM diagramming and vector drawing software using the Event-driven Process Chain Diagrams Solution from the Business Processes area of ConceptDraw Solution Park.

Business process Flow Chart — Event-Driven Process chain (EPC) diagrams

Event-Driven Process chain Diagrams for improvement throughout an organisation. Best software for Process Flow Diagram. The Event-driven Process Chain (EPC) Diagrams allows managers to plan processes and resources.

Example of DFD for Online Store (Data Flow Diagram)

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.

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 DIAGRAM makes it easy to create an ERD, and hundreds of other diagrams, in minutes.

Process Flow Chart Symbol

Process Flow Charts are very popular and widely used in chemical and process engineering for representation a general flow of plant processes and equipment. If you need often draw them, the ConceptDraw DIAGRAM diagramming and vector drawing software extended with tools of Flowcharts Solution will be useful for you.
The mostly used set of process flow chart symbols includes the following: Rectangle (box) process flow chart symbol, Rounded rectangle, Circle, Diamond.

SSADM Diagram

The vector stencils library SSADM from the solution Systems engineering contains specific symbols of SSADM diagrams for ConceptDraw DIAGRAM diagramming and vector drawing software. The Systems engineering solution is contained in Software Development area of ConceptDraw Solution Park.
The example below illustrates the waterfall model used in SSADM. This model involves 5 stages of developing a product such as requirements specification and its' analysis, design, coding and testing.

Program Evaluation and Review Technique (PERT) with ConceptDraw DIAGRAM

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.
