UML Use Case Diagram Example. Social Networking Sites Project
In the early stages of a development project, use case diagrams are used to describe real-world activities and motivations.
A use case diagram (use case: In a use case diagram, a representation of a set of events that occurs when an actor uses a system to complete a process. Normally, a use case is a relatively large process, not an individual step or transaction.) is a dynamic or behavior diagram in UML.
Use case diagrams are valuable for visualizing the functional requirements of a system that will translate into design choices and development priorities. You can refine the diagrams in later stages to reflect user interface and design details.
They also help identify any internal or external factors that may influence the system and should be taken into consideration.
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw DIAGRAM is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw DIAGRAM — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools.
This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw DIAGRAM — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management tools.

All computer networks differ by various params, and their size is one of them. As global area networks are the biggest, personal area (PAN) networks are the smallest. Personal computers, smartphones and other devices that have possibility to connect to Internet form a personal network.
This diagram was created using ConceptDraw Computer Network Diagrams to represent a typical components of Personal area network. A personal area network (PAN) is the connection of IT devices around an individual person. This sample of personal area network involves a notebook, a personal digital assistant (PDA), and a portable printer. Commonly a PAN contains such wireless devices as mouse, keyboard, smartphone and tablet. A wireless connection is typical for a PAN.

Unfortunately, a man can’t predict the future and no one is safe from natural disasters, such as floods, earthquakes, hurricanes or fires. Nonetheless, what you can do to ensure safety for you and your relatives is to create an emergency plan, so everyone will know what to do if emergency happens. Keep that plan simple and train it several times a year so that no one could forget any details of it.
Fire and emergency plans are important to supply people with a visual safety solution. This diagram presents a set of standard symbols used to depict fire safety, emergency, and associated information. Using clear and standard symbols on fire emergency plans provides the coherence of collective actions , helps to avoid embarrassment, and improves communications in an emergent situation. The fire emergency symbols are intended for the general emergency and fire service, as well as for building plans ,engineering drawings and insurance diagrams. They can be used during fire extinguishing and evacuation operations, as well as trainings. It includes vector symbols for emergency management mapping, emergency evacuation diagrams and plans.

Describing a workflow or approval process can take hours and be too complicated, especially since there are options to do it quickly and vividly. Diagrams called flowcharts replace long paragraphs of boring text and represent information in a graphic way. You can draw one on paper or you can use flowchart software to do it quickly and scalable. This kind of software is easy to use and you don’t need any special skills to start using it. In addition, there are a lot examples and predesigned templates on the Internet.
Flowcharts are a best tool for staking out a huge and complex process into some small readable parts. Surely, flowcharts can be drawn manually but the use of standard symbols that make it clear for a wide audience makes a software tool preferred for this task. The core for a successful flowchart is its simplicity. That is why often before beginning making flowchart through software, people draw the sketch on a piece of paper. Designing an effective flowchart means the combination of the data needed to be shown and the simplicity with which you depict it.

Structured-systems analysis and design method uses data flow diagrams to represent the process of data flowing through a system. Talking about this might be useless without a proper example of DFD for online store (Data Flow Diagram). This DFD example shows all the distinctness that a diagram can bring into a scattered data structure.
Data flow diagrams are used to show how data is processed within some business processes. Making DFD is a common practice for business process modeling and analysis. This diagram represents the online store business flow. It describes inputs and outputs within online selling process and depicts the interactions between its participants. This DF diagram can be used by system analysts to create an overview of a business, to study and discover its inherent strengths and weak points.
