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 talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems.
The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.
26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

When used in different areas, flowcharts use specific symbols to depict different elements. ConceptDraw DIAGRAM offers libraries of symbols for many areas. One of such libraries is flowchart symbols accounting, which provides symbols for accounting diagrams. Activity-based costing calculates the costs of all products and services based on activities in an organization. A type of accounting flowchart that shows how costs are assigned to products with resources and activities is called Activity-based costing (ABC) flowchart. It can be designed in a digital drawing software such as ConceptDraw DIAGRAM.
Here is an accounting flowchart template and symbols. These flowchart symbols are applied for making accounting flow charts in ConceptDraw DIAGRAM and with its Accounting Flowcharts solution. An accounting flowchart is a specific type of a flow diagram. Practically a number of flowchart-type diagrams commonly utilized to clarify many parts of an accounting department working process. Accounting flowchart assists a process of preparing accounting documentation. It shows who responsible for implementation of each step in the workflow of accounting department.
