Modelling Concepts for Business Engineering - EPC
Event-driven Process Chain
The Event-driven Process Chain (EPC) Diagrams allows engineers visually present process models for they implementation. The EPC diagram shows various business processes in terms of work flows.
ConceptDraw DIAGRAM includes tools that are specifically designed to facilitate the process of depicting business processes.

The Event-driven Process Chain Diagrams solution extends ConceptDraw DIAGRAM software with EPC templates, samples, and vector shape library for the drawing of EPC diagrams.
The Event-driven Chain Diagrams solution assists in visualization of modelling concepts for business engineering.
TEN RELATED HOW TO's:
ConceptDraw gives the ability to draw simple diagrams like flowcharts, block diagrams, bar charts, histograms, pie charts, divided bar diagrams, line graphs, area charts, scatter plots, circular arrows diagrams, Venn diagrams, bubble diagrams, concept maps, and others.

Developing a software project supposes architecture first. To make it proper, you can use data flow diagram model in your current project.
The data flow diagram represents the Model of small traditional production enterprise that is made using Yourdon and Coad notation. It shows how the data is transfered through a process. According to the notation of Yourdon and Coad a process is represented by circles and data stores are drawn using parallel lines. This DFD was created using the ConceptDraw Data Flow Diagrams solution. Using this solution one can visualize data flow accordingly to the rules of two basic notations used for data flow modeling.

IT world is extremely rational and logical. So what can be more precise than Software Diagrams to rate the results of work? Visual statistics is the best way to understand the data.
This figure demonstrates the data flow diagram (DFD), which was created to describe the electronic system of custom purchase. This is the process of buying using electronic bar code scanning system. Such systems are used in large stores. The cashier scans the bar code, the system outputs the data on the price of the goods and carries out a purchase process. This DFD utilizes the Gane/Sarson notation. To create it The ConceptDraw DFD solution has been applied.

Every engineering project starts from a terms of reference document. The next stage of developing is a technical drawing, which requires using appropriate software. However, revisions and discussions about requirements are possible at any stage of development.
This technical drawing demonstrates a schematic flow diagram of pulp reclaiming. This diagram of magnetite pulp reclaiming is created using ConceptDraw Chemical and Process engineering solution, The solution delivers more than 460 vector graphic icons and connectors. Generally, it is intended for designing process and instrumentation diagrams (P&ID) for chemical and process engineering. block flow diagrams (BFD), process flow diagrams (PFD) for chemical industry.

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.

Database structures are usually described by ER-diagrams which represents entities as boxes with lines-connections between them. You can create any entity-relationship diagram (ERD) by means of ConceptDraw DIAGRAM using ready-to-use templates and special libraries containing all the needed symbols and shapes. Creating a model for your database from now on can take just a few minutes.
ERD (entity relationship diagram) designed to show the logical structure of databases. It intended to depict the relationships between data components (entities). ERDs are a popular tool for software engineers and architects. Using ERD they can manage the every aspect of database design. Also ERD can be used as guidelines for testing and communications before software release. This diagram represents the file reference system of the WordPress web platform. Because entity relationship diagrams have such a broad application area through the prevalence of database technology, it can be applied for a wide range of users.
