UML Block Diagram
UML Building Blocks
The UML building blocks determine as things, relationships and diagrams.
There are four types of things in UML: Structural, Behavioral, Grouping and Annotational.
Sructural things (the static part of the model):
Class:
Class represents a set of objects that have the same structure, behavior, and relationships with objects of other classes. Classes are represented as boxes that consist of name, attributes, operations, and responsibilities.
Interface:
Interface is an abstract class that defines a set of operations that the object of the class associated with this interface provides to other objects.
Collaboration:
Collaboration determines interactions between the elements.
Use case:
Use case is a description of the system behavior on the request from the outside of this system.
Component:
Component describes the physical part of the system.
Node:
Node is a resource available during the run time.
Behavioral things (dynamic part of the model):
Interaction:
Interaction is a set of messages that the elements exchange for execution the tasks.
State machine:
State machine defines the states of the object that go in response to the events.
Grouping things (the mechanism for grouping the UML model elements):
Package:
Package groups the classes and other packages.
Annotational things (the mechanism for capturing the remarks, descriptions, and comments of the UML model elements):
Note:
Note is a textual explication.
Relationship :
Association:
Association is a relationship that connect two classes.
Dependency:
Dependency is a relationship when some changes of one element of the model can need the change of another dependent element.
Generalization:
Generalization is an association between the more general classifier and the more special classifier.
Realization:
Realization is a relationship between interfaces and classes or components that realize them.
Diagrams:
There are the following types of UML Diagrams: Class, Component, Composite Structure, Deployment, Object, Package, Activity, State Machine, Use Case, Communication (Collaboration), Interaction Overview, Sequence, and Timing.

Using the libraries of the Rapid UML Solution for ConceptDraw DIAGRAM you can create your own visual vector UML diagrams quick and easy.
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.
TEN RELATED HOW TO's:
UML Object Diagram. Design Elements →
UML Object Diagram shows the structure of a modeled system at a specific time. ConceptDraw has 393 vector stencils in the 13 libraries that helps you to start using software for designing your own UML Diagrams. You can use the appropriate stencils of UML notation from UML Object library.
UML Software →
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. The Rapid UML Solution for ConceptDraw DIAGRAM presentsthe intuitive RapidDraw interface that helps you to make the UML Diagram of any of these 13 types quick and easy.
Business Process Elements: Swimlanes →
ConceptDraw has 142 vector stencils in the 8 libraries that helps you to start using software for designing own Business Process Diagrams. Use Swimlanes library with 20 objects from BPMN.
Use the Best FlowChart Tool for the Job →
The ConceptDraw DIAGRAM is a best flow chart tool for the job. The samples and templates included in the basic set allows users to draw any type of a flowchart. The vector stencils created by designers give ability to draw great-looking flowchart. Flowcharts give to users the ability to represent structural data visually.
UML Class Diagram Constructor →
UML Class Diagrams is a type of static structure diagram that is used both for general conceptual modeling of the systematics of the application, and for detailed modeling translating the models into programming code. It describes the structure of a system by showing the: classes of a system, attributes, operations, and the relationships between them. The Rapid UML Solution for ConceptDraw DIAGRAM includes the UML Class Diagram library that helps you to design the UML Class Diagram quick and easy. You can simply and quickly drop the ready-to-use objects from the library into your document to create the UML Class Diagram.
Functional Flow Block Diagram →
You need to draw a Functional Flow Block Diagram? You are an artist? Now it doesn't matter. With Block Diagrams solution from the "Diagrams" area for ConceptDraw Solution Park you don't need more to be an artist to design the Functional Flow Block Diagram of any complexity.
Network Components →
Drawing the network diagrams is a complex process which requires a lot of efforts, time and artistic abilities. ConceptDraw DIAGRAM offers the Network Layout Floor Plans Solution from the Computer and Networks Area with variety of predesigned network components for drawing network layout floor plans in minutes.
Flow Chart Symbols →
If you need to describe some process, diagramming is a perfect tool for almost any imaginable purpose. The set of the most commonly used flow charts symbols is quite wide and includes symbols for operations, processes, data inputs and outputs. You can see the full list of all the symbols used for flowcharting in Flowcharts solution from Diagrams area in ConceptDraw Solution Park. A flow chart is often used for visual representation of a sequential process flow. The flowchart approach to any process is to divide it into some sequential actions. What makes a flow chart so popular and clear to make out is the set of standard flowchart symbols that has the same reading independently from processes described with their applying. The current drawing represents the vector library containing the pack of standard flowchart symbols. This library is supplied with ConceptDraw Flowcharts solution.
