The Best Tool for Business Process Modeling
Event Driven Process Chain (EPC)
An event-driven process chain is well known as well as a commonly used type of flowchart, especially within the business process modelling science. They can be also used in order to configure a so called “enterprise resource planning” implementation. They can be very useful in the process of the business process improvement as well as for controlling the work share with instances of the autonomous workflows. It is a process chain used in a “workflow management” and in other fields of the business activity.
The method of the “event-driven process chain” was developed by August-Wilhelm Scheer in 1990s within the framework of so called “Architecture of Integrated Information Systems”. Nowadays different businesses use the made event-driven process chain diagrams for laying out their business process workflows, used by many companies for many different business processes, such as analyzing, redesigning the business processes themselves as well as for modelling.
The mentioned “event-driven process chain method” was the one developed within the framework of “Architecture of Integrated Information Systems” (or simply “ARIS”), as it was mentioned before, and the statement that event-driven process chains are ordered graphs was also one of those found in other so called “directed graphs”. There are no restrictions appearing for existing on the possible structure of EPCs. At the same time, the non-trivial structures involve parallelism having the so called “ill-defined execution semantics”. Thus, in this case they are known to be called as “UML activity diagrams”.
There are a few elements which are used in the usual “event-driven process chain diagram”. They can be events, which are simply are passive elements in the described before “event-driven process chains”. They are used for describing under what circumstances a function (or a process) works. They also can be used for clarifying which of them a process results in or for stating a function. At the same time, “functions are known to be the “active” elements in an event-driven process chain, being used for modelling the activities or tasks within one company, describing the transformations simply from an initial state to a resulting one.
The process owner is known to be responsible for a function, being a part of some organization unit usually represented in a way of a square with a single vertical line. “Organization units” are meant to be determining which exactly organization within one particular structure of some enterprise is the one responsible for some specific function, represented in a way of an ellipse with a single vertical line.
The material, resource objects and information in the event-driven process chain portray objects in the real world, such as business entities, objects and other, inputting data serving it as the basis for a function or outputting it produced by a function. The so called “logical relationships” between elements in the control flow in the event-driven process chain are known to be described by the “logical connectors”. They are known to be functions and events. Having these “logical connectors”, it is always possible to split the control flow from one flow to at least two or even more flows. It is usually done for synchronizing the control flow from two or over two flows to just one.
A control flow as an element of an event-driven process chain is used for connecting events with functions, logical connectors or process paths. They are used for creating the logical interdependencies as well as the chronological sequence between them. Such “control flow” element is usually represented simply as a dashed arrow, when the “information flows” show the connections between different functions and so the input (or output) data. Another element of any event-driven process chain is the “organization unit assignments”. They are used for showing the different connections between an organization unit itself and the function, which it is responsible for. One of the last, “process paths” element is commonly used as a navigation aid in the event-driven process, for showing the connection from (or to) other processes. Every process path is known to be represented in a way of a compound symbol, being composed of a function symbol. In order to employ such process path symbol in an “Event-driven Process Chain diagram”, this symbol gets connected to the process path symbol, indicating the fact that this particular process incorporates the entirety of a second process which is represented by a single symbol.
It is also important to mention the three existing kinds of logical relationships within the event-driven process chains, which are branch and merge, fork and join and an 'OR' relationship. The first one correspond to making the decision of which exactly path it is better to choose out of a few control flows. A “fork and join” one corresponds to activating all the paths in the “control flow”, when “OR” relationship corresponds to activating one or over one in the control flows. Such opening “OR” connector may have one incoming control flow as well as two or more “outgoing” control flows, so when the condition is fulfilled, the mentioned “opening OR” connector can activate one or over control flows. When there is at least one of all the incoming control flows finally activated, then the closing “OR connector” can pass the control to the next element, going after it.

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data.
This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.

If you need to describe some process, diagramming is a perfect tool for almost any imaginable purpose. The set of the most commonly used flow charts symbols is quite wide and includes symbols for operations, processes, data inputs and outputs. You can see the full list of all the symbols used for flowcharting in Flowcharts solution from Diagrams area in ConceptDraw Solution Park.
A flow chart is often used for visual representation of a sequential process flow. The flowchart approach to any process is to divide it into some sequential actions. What makes a flow chart so popular and clear to make out is the set of standard flowchart symbols that has the same reading independently from processes described with their applying. The current drawing represents the vector library containing the pack of standard flowchart symbols. This library is supplied with ConceptDraw Flowcharts solution.

Software development flourishes nowadays. Students have tons of educational information and courses that would fit every taste. And it's no secret that knowing how to draw data flow diagrams is a useful skill for a future software architect. The diagrams help a lot in understanding how to storage data effectively and how data processes within a system.
This data flow diagram represents the model of small traditional production enterprise. It was created using Yourdon and Coad notation. The data flow diagram include four main objects: entity, process, data store and data flow. Yourdon and Coad notation uses circles to depict processes and parallel lines to represent data stores. Dataflows are shown as arrowed lines. They are labeled with the description of the data that move through them. Dataflow's role is to deliver the pieces of information. A process's function is to transform. the input data flow into output data flow. ConceptDraw Data Flow Diagrams solution contains the data flow diagram symbols of both Yourdon-Coad and Gane-Sarson notations and a set of handy templates to get started with DFD.

You can use many tools to create a representation of a system behavior or a scheme of objects relationships. Some of them are quite abstract and useless, and some, like UML tools help clarifying both the structure and the behavior of a system. There are various types of uml diagrams and tons of examples explaining the difference between them.
UML 2.2 specification has many kinds of diagrams. They are divided into two groups( structure and behavior diagrams). This class diagram shows the hierarchical structure of UML 2.2 specification. Class diagram - the most suitable tool for this task because it is designed to describe basic structure of a system. This diagram can be use as a visual aid for learning UML.
