Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems.
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.
There are seven types of Structure Diagrams that must be present in any modeled system:
UML Class Diagram is a type of Structure Diagrams that shows the classes of a system, attributes, operations, and the relationships between them.
Package Diagrams
UML Package Diagram is a type of Structure Diagrams that represents the packages of the model and dependencies between them.
Object Diagrams
UML Object Diagram is a type of Structure Diagrams that shows the objects of the system and attributes, and relations between the objects at a certain moment of time.
Use Case Diagrams
UML Use Case Diagram is a type of Behavior Diagrams that displays the dependencies between the actors and use cases.
UML Use Case Diagram displays the system on the conceptual level.
Sequence Diagrams
UML Sequence Diagram is a type of Interaction Diagrams that describes the interactions between objects and classes that are involved in the scenario and the sequence of messages exchanged between them.
Collaboration Diagrams
UML Communication Diagram in UML 2.0 (Collaboration Diagram in UML 1.x) is a type of Interaction Diagrams that displays the interactions of objects using the sequenced messages.
Activity Diagrams
UML Activity Diagram is a type of Behavior Diagrams that graphically describes decomposition of the some activity on the components.
Component Diagrams
UML Component Diagram is a type of Structure Diagrams that shows how components are connected to larger components or software systems, and shows the dependencies among these components.
Deployment Diagrams
UML Deployment Diagram is a type of Structure Diagrams that shows the physical deployment of information generated by the software programs.
State Machine Diagrams
UML State Machine Diagram is a type of Behavior Diagrams that displays the finite state machine with states and state transitions.
Timing Diagrams
UML Timing Diagram in the UML 2.0 is a specific type of Interaction Diagrams that describes the timing constraints.
UML Timing Diagrams describes the behaviors of the objects during a certain period of time.
Interaction Overview Diagrams
UML Interaction Overview Diagram is a type of Interaction Diagrams that describes an overview in which the nodes represent interaction diagrams.
Composite Structure Diagrams
UML Composite Structure Diagram is a type of Structure Diagrams that shows the internal structure of a class and the interactions of elements of the internal structure of the class.

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.
The ability to develop UML diagrams as quickly as the ideas come. The solution uses ConceptDraw RapidDraw techniques. The result is a vector graphic document.
There are many ways to define the flow of information within a system. Structured-systems analysis method often uses data flow diagrams to show data flow, data storages and data processing visualization. These diagrams are easy to develop and quite useful.
Here is a dataflow diagram presenting an example of the manufacturing process flow. The oval process shapes represent a process that controls data within the current system. The process may produce data or make some action based on data. Data flows are represented by lines. They show the movement of information through the system. The direction of the data flow is depicted by the arrow. The external entities are shown by rectangles. They represent the external entities interacting with the system. The data store objects (unclosed rectangles) are used to show data bases participating in a process flow.
The UML diagram is a powerful tool which lets visually represent all system's components, the interactions between them and relationships with external user interface.
The Rapid UML solution for ConceptDraw DIAGRAM software offers diversity of UML flowchart symbols for drawing all types of UML diagrams.
A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks.
Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.

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.
The vector stencils library Rail transport contains clipart of railway transport for ConceptDraw DIAGRAM diagramming and vector drawing software.
Use it to draw illustrations of trains and transportation of passengers and goods by railroads.
State Diagram UML of Online Store. This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the work of the medical shop and is used at the creation of the medical shop or pharmacy project, for understanding the process of shopping in the medical shop, for keeping purchases, for medical supplies.
