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.

Any business process consists from a number of tasks carrying out the certain business goal. It is useful to diagram business processes to ensure that they are as foolproof, logical and sequential as possible. This business process diagram describes a typical booking process flow by the example of a cab booking process. It can be used as a roadmap for any booking system implementation. Diagramming a business process allows you to look at the entire project and take into account all types of possible scenarios. Business process diagram helps you investigate and clarify the process thoroughly so that you can find out how it can be improved. Business process diagram supports team communications by ensuring that each process element is clear and everyone in the team is on the same page.
Sometimes your company brings you less profit than you expect it to be, and it’s difficult to reveal the causes. Maybe it’s time to learn new technologies, because business diagram are easily developed by means of special software, so you won’t make any extra effort. In return, you will increase your productivity and get more done in a less time.

There are many tools to manage a process or to illustrate an algorithm or a workflow. Flowcharting is one of those tools. However, it may be difficult to show complex processes that require multiple attributes or several people in a simple flowchart, so a cross-functional flowchart would be a solution for that situation. To create such flowchart, group processes and steps to labeled rows or columns, and divide those groups with horizontal or vertical parallel lines. It is worth mentioning that there are different types of cross-functional flowcharts, like opportunity or deployment flowchart.
This diagram shows a cross-functional flowchart that was made for a trading process. It contains 14 processes, distributed through 5 lines depicting the participants who interact with the process. Also there are connectors that show the data flow of information between processes. The cross-functional flowchart displays a detailed model of the trading process, as well as all participants in the process and how they interact with each other. The lines in the flowchart indicates the position, department and role of the trading process participants.

In software engineering, it is important to understand how the system would cooperate with external sources, like data sources. To give this information a visual representation, data flow diagrams (DFD) were used for years. The entire system is usually divided into smaller ones, and all of them process data flows in appropriate ways.
The visualizing business processes which engages the data transfer, is commonly preformed using DFDs (data flow diagrams). DFD is used to show the data flow processing and transformation. This DFD represents the electronic system of a customer purchase. It was created using Gane/Sarson notation. Data flow diagrams helps you to sort through and clarify transferring process making it available for analysis, and representation. ConceptDraw DFD solution introduces the vector library, containing the full set of icons from DFD notations.

Data flow diagrams are the graphical tool, used in the visualization of data flow of some data processing systems. It is the valuable process modeling tool. Also designing DFD is the important component of the initial part of any information system development project. The standard symbols are used to represent the interaction of a system components and how various kinds of components influence on data flow. The ConceptDraw Data Flow Diagrams solution is design to assist professional software engineers in making DFDs according to Gane and Sarson, and Yourdon and Coad notations.

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity.
This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.
