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
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.
Pic.2. UML deployment diagram
Use the UML Deployment Diagram library to create such diagrams in ConceptDraw 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.
Pic.3. UML statechart diagram
Use the UML Statechart Diagram library to create such diagrams in ConceptDraw 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.
Pic.4. UML activity diagram
In ConceptDraw DIAGRAM such diagrams are represented in the UML Activity Diagram library.
A type of interaction diagram. Sequence diagrams describe a sequence of interactions between objects.
Pic.5. UML sequence diagram
To draw such a diagram, use the UML Sequence Diagram library.
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.

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.
Pic.7. UML class 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.
Pic.8. UML component diagram
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.

When we start to speak about databases, we must always mention database structure visualization. One of the most common ways to do it is to create an entity relationship diagram, and to put appropriate symbols on it. It is important either for database projecting and for its' future maintenance.
Entity Relationship Diagram describes data elements and their relationships within a database. There are a set of special symbols that depict each element of an entity relationship diagram. Entities - represents some stable components such as supplier, employee, invoice, client, etc. Relation symbols show how the entities interact. Attributes define characteristics of the relationships. Attributes can be one-to-one or many-to-many. Physical symbols is used in the physical models. They represent items such as fields, tables, types and keys. ERD physical symbols are the building material for the database. Notation lines are used to illustrate the relationships. The most common method is Crow’s Feet notation. You can use ConceptDraw Entity-Relationship Diagram (ERD) solution to represent a database using the Entity-Relationship model.

If we divide computer networks by scale, we get several main categories. The smallest network is PAN, as it connects personal devices themselves, and as the number of users grows, a local area network can be recognized, and campus area networks (CAN) connects several local networks located within some area like a university or a corporation. Computers connected to CAN share public educational materials and list of CAN network examples includes such prestigious universities like Stanford and Carnegie Mellon.
This is an example of a computer network diagram created for a campus area network. It was created using using ConceptDraw solution for the Computer and Network diagramming. The specific of this sample campus network is its distribution. It is rather broad to embrace a big campus territory. This diagram can be applied as a template for designing custom area network topology diagram for a particular educational institution.

Database structures are usually described by ER-diagrams which represents entities as boxes with lines-connections between them. You can create any entity-relationship diagram (ERD) by means of ConceptDraw DIAGRAM using ready-to-use templates and special libraries containing all the needed symbols and shapes. Creating a model for your database from now on can take just a few minutes.
ERD (entity relationship diagram) designed to show the logical structure of databases. It intended to depict the relationships between data components (entities). ERDs are a popular tool for software engineers and architects. Using ERD they can manage the every aspect of database design. Also ERD can be used as guidelines for testing and communications before software release. This diagram represents the file reference system of the WordPress web platform. Because entity relationship diagrams have such a broad application area through the prevalence of database technology, it can be applied for a wide range of users.

Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.
