UML Diagrams with ConceptDraw DIAGRAM
UML (Unified Modeling Language) is a general-purpose modeling language used to represent the structure of complex software in a visual form, and employed in software engineering. UML diagrams are also efficient for documenting complex computer systems and software. Such visual models facilitate communication between the customer, system analysts and programmers, who write the source code. In addition, it's much easier for new programmers to understand the source code when a detailed UML diagram of it is available. Previously, when a programmer resigned a part of his work was gone with him because the code-creating process took place exclusively in his head. Now a newcomer can understand and get familiar with someone else's code without much trouble.
Programming languages may use operations and methods which are basically same, though vary by names and graphical notations. The UML language defines standards not only for operations and methods of programming languages, but also for their terminology.
So, using UML diagrams for visual modeling will help you to improve the final software products, simplify the process of its creation and meet the deadlines.
ConceptDraw DIAGRAM is a professional software product designed for creating detailed UML diagrams. A large number of libraries with ready-made objects for UML diagrams and task-oriented templates let you create UML diagrams of any complexity without effort.
To draw a diagram, just drag the required objects from the corresponding library onto the document page, then connect them with connectors appropriate for diagrams of this type.
There are 8 types of UML diagrams:
Use case diagram:
Diagrams of this type represent a list of operations performed by the system. Such diagrams are also called functional diagrams, as the list of the system's functions is created based on them, in accordance with the specified requirements.
Use case diagrams are used to describe business processes in automated applications and to define requirement for software to be developed. They depict objects from the system and application domain as well as the tasks performed by them.

To draw diagrams of this type, use the UML Use Case Diagram library in ConceptDraw DIAGRAM
Deployment diagram:
UML diagrams of this type serve to analyse the hardware used in system implementations, interaction between the processor and other components. As a rule, such diagrams are used in the beginning of designing to determine the hardware configuration of the system.

Use the UML Deployment Diagram library to create such diagrams in ConceptDraw DIAGRAM
Statechart diagram:
Statechart diagrams serve to model possible states of the objects in the system. They also depict the sequence of actions required for transition between the states.

Use the UML Statechart Diagram library to create such diagrams in ConceptDraw DIAGRAM
Activity diagram:
Same as Statechart diagrams, such diagrams show the states of objects in the system. The difference is that they can also depict forks for transitions from one state to another. These diagrams can be used to describe behavior algorithms of objects. You may also use them to create flow charts.

In ConceptDraw DIAGRAM such diagrams are represented in the UML Activity Diagram library.
Sequence diagram:
A type of interaction diagram. Sequence diagrams describe a sequence of interactions between objects.

To draw such a diagram, use the UML Sequence Diagram library.
Collaboration diagram:
A collaboration diagram is also a type of interaction diagram, but unlike sequence diagrams these diagrams instead of the sequence of interactions between objects describe all variants of such interactions, regardless the sequence.

Class diagram:
They help to create graphical logical models of a system, further used to create the source code for the classes represented on the diagram.
UML class diagrams describe relationship between classes and interfaces. We recommend to create class diagrams using the Booch OOD template from the ConceptDraw STORE.

Component diagram:
On diagrams of this type, also known as module diagrams, classes and objects are distributed by components or modules. This is very convenient for designing large systems which may count hundreds of components.

Use the UML Component Diagram library for drawing diagrams of this type.
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.

Talking about companies, that have influenced the entire industry, we should mention Cisco and it’s influence on network design. Nowadays, this equipment has became a kind of standard, and Cisco icons, shapes, stencils, symbols and design elements are easily recognized among others. You can use these icons to develop a network diagram of any complexity.
When dealing with creating a pack of network documentation, system administrator often have to depict a network containing a network equipment of such a well-known manufacturer as Cisco. As Cisco has developed its own production standard icons that are strongly recommended to use in Cisco network diagrams. The best way to draw Cisco Network diagram Cisco certified icons is using ConceptDraw solution for Cisco Network Diagrams. Using Cisco symbols library provided by this solution allows system administrator, or network architect to design a prototype of a new network or document an existing one.

Any information system receives data flows from external sources. In order to visualize them there is a list of data flow diagram symbols that describes how the system components cooperate. If you want to create a data flow diagram, ConceptDraw DIAGRAM Solution Park has DFD Library that contains both Yourdon and Gane-Sarson notations.
This figure shows the content of vector libraries, delivered with ConceptDraw solution for data flow diagram (DFD). There are three libraries composed from about 50 vector objects used to make data flow diagrams.
They include a complete set of objects utilized by Yourdon-Coad and Gane-Sarson notations - two primary notations that are apply for data flow diagramming. Also, one can discover additional "Data flow diagram (DFD)" library that provides a data flow diagram elements for designing level 1 and context-level data flow diagrams.

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.
