UML Activity Diagram. Design Elements
UML Activity Diagram is a type of Behavior Diagrams that graphically describes decomposition of the some activity on the components.
Activity Diagrams are used in modeling of business processes, technological processes, sequential and parallel computations.
UML Activity Diagram allows to show the sequence, branching and synchronization of processes.
To design UML Activity Diagrams use the following shape types:
- rounded rectangles to describe the actions;
- diamonds to describe decisions;
- bars to represent the start or end of the activities that occur at the same time;
- black circle to indicate the start of the workflow;
- encircled black circle to indicate the end of the workflow;
- arrows to represent the order in which activities happen.
Activity Diagrams were a specialized form of the State Diagrams in UML 1.x. In UML 2.x, the Activity Diagrams were reformed and now are based on Petri net-like semantics that allows to model a lot more situations.
The Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.
To design an Activity Diagram use the UML Activity Diagram library.

ConceptDraw Rapid UML solution provides UML Activity Diagram library of vector stencils for activity diagram design elements like rounded rectangles of activities, diamonds of decisions, bars of the start (split) or end (join) of concurrent activities, black circle of the start (initial state) of the workflow, encircled black circle of the end (final state), etc.
Use UML Activity Diagram library to draw your own activity diagrams that show the business and operational stepwise workflows of components in your system.
All libraries for creating UML diagrams are available inside the ConceptDraw DIAGRAM Templates and samples are located in the Rapid UML section of ConceptDraw STORE.

UML State Machine Diagram.Design Elements →
UML state machine's goal is to overcome the main limitations of traditional finite-state machines while retaining their main benefits. ConceptDraw has 393 vector stencils in the 13 libraries that helps you to start using software for designing your own UML Diagrams. You can use the appropriate stencils of UML notation from UML State Machine library.

Accounting Flowchart Symbols →
It doesn’t matter what kind of business you have, a bar or a gym, there are common concepts for any of them. One of those concepts is accounting, and to facilitate the work with the figures, you can use accounting flowchart symbols and create a clear and representative scheme. You can create flowchart for auditing, tax accounting and even for planning your own budget. A graphical tool for displaying successive processes is flowchart. This method is mostly suited to represent an accounting process. The sequence of steps in the accounting process usually consists of standard accounting procedures, that can be depicted by using a minimal number of symbols, applied for the basic flowcharting. The advanced opportunity to create professional Accounting Flow charts is provided by ConceptDraw Accounting Flowcharts solution. It includes contains a library of accounting flowchart symbols used when drawing the accounting process flow.

Data Flow Diagram →
There are many ways to define the flow of information within a system. Structured-systems analysis method often uses data flow diagrams to show data flow, data storages and data processing visualization. These diagrams are easy to develop and quite useful. Here is a dataflow diagram presenting an example of the manufacturing process flow. The oval process shapes represent a process that controls data within the current system. The process may produce data or make some action based on data. Data flows are represented by lines. They show the movement of information through the system. The direction of the data flow is depicted by the arrow. The external entities are shown by rectangles. They represent the external entities interacting with the system. The data store objects (unclosed rectangles) are used to show data bases participating in a process flow.

Swim Lane Diagrams →
Job duties in small companies are usually spread randomly among workers, causing lots of problems and misunderstanding. One of the ways to restore order in business processing is to create a cross-functional flowchart with swim lanes that would represent every step in production system. Another advantage of using swim lanes flowchart is that it represents not only processes, but people responsible for them. Swim lane diagram is a kind of a process flow diagram. Its special feature is that it joins the features of process flow diagrams with organizational charts. Thus, a swim lane diagram display a participant of the business process in a conjunction with general flow of the business system. A swim lane diagram is looks similar to a swimming pool's lanes. Lanes can be horizontal and vertical. The lanes are pointed out relatively to resource name, which is assigned on implementation of the given part of the business process. ConceptDraw Business Process Mapping solution delivers the ability to design develop swim lanes flowcharts using the vector graphic objects of Swim Lanes library.

SWOT Analysis →
Sometimes it’s quite useful to look on a problem from another view. To gain insight into an obstacle you should use SWOT analysis, and this will help you to see the whole situation. When composing a SWOT matrix, you divide your problem onto four elements - strengths, weaknesses, opportunities and threats and place them into matrix. This sample SWOT analysis matrix of the athletic shoes producing company was designed on the base of template provided by ConceptDraw SWOT and TOWS Matrix Diagrams solution. It delivers number of easy-to-use templates and samples of SWOT and TOWS matrices for ConceptDraw DIAGRAM. Applying one of these templates, enables to quickly find out Strengths, Weaknesses, Opportunities, and Threats. After creating a list managers can consider methods the business can use to amplify strengths and to decrease weaknesses; realize opportunities; and avoid threats.
