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.
Example 1. UML Class Diagram. AbstractFactory pattern
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.
UML Timing Diagram as special form of a sequence diagram are used to explore the behaviors of objects throughout a given period of 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 Timing library.
The vector stencils library Yourdon and Coad Notation from the solution OOAD contains specific symbols of the Yourdon and Coad notation such as data store symbol, data process symbol, loop symbol for ConceptDraw DIAGRAM software.
Use ConceptDraw DIAGRAM diagramming and vector drawing software enhanced with Computer and networks solution to draw different types of network diagrams: physical layout and topology, LAN and WAN, Cisco, Apple, Wi-Fi wireless and Ethernet wired networks, etc.
Special libraries of highly detailed, accurate shapes and computer graphics, servers, hubs, switches, printers, mainframes, face plates, routers etc.
Today, we can’t imagine our lives without daily data exchange. To call a set of devices that can be connected with each other a computer network, we must be sure that these devices support appropriate protocols to transfer data. A network consisting of personal devices is private, and global computer networks, for example, Internet, connects network nodes worldwide.
This diagram represents a computer telecommunication network. The network depicted on the current diagram is featured with networked communication devices that provide data exchange through Internet. The network interconnections and connections between Internet nodes are settled using the cable media and wireless media. The nodes are the network workstations (terminals). and host computers. This network diagram was drawn with ConceptDraw DIAGRAM and its Computer and Networks Diagrams solution.

Database design is an important part of any project, as databases become more and more complex nowadays. To make the model more representative, entity relationship diagrams are widely used in software engineering area. These diagrams show sets of entities as rectangles connected via lines labeled with their cardinalities.
This an example of the ER-diagram developed to store information regarding some online role-playing game. It includes three main elements of ER diagram: entities, relationships and attributes. The entities, attributes and relationships on this ER-diagram is depicted according to the Chen's notation. Chen's notation for Entity Relationship diagrams admits using of rectangles to depict entities, ovals for attributes and ,at least, diamonds to show relationships. ConceptDraw Entity-Relationship Diagrams solution was applied as ERD software to create this diagram.
In any unclear situation create a workflow diagram. Workflow diagrams help to understand processes, find bottlenecks and fix the process. When you create workflow diagram using ConceptDraw DIAGRAM software you are able to focus on thinking, not drawing, that makes you as effective as possible.
Venn diagrams are illustrations used in the branch of mathematics known as set theory.
Use ConceptDraw DIAGRAM to quick and easy design your own Venn Diagram of any complexity.
Electrical plan is a document that is developed during the first stage of the building design. This scheme is composed of conventional images or symbols of components that operate by means of electric energy. To simplify the creation of these schemes you can use house electrical plan software, which will not require a long additional training to understand how to use it. You only need to install the necessary software ant it’s libraries and you’ll have one less problem during the building projection.
Any building contains a number of electrical systems, including switches, fixtures, outlets and other lightening equipment. All these should be depicted in a building electrical plans and included to general building documentation. This home electrical plan displays electrical and telecommunication devices placed to a home floor plan. On the plan, each electrical device is referenced with the proper symbol. Electrical symbols are used for universal recognition of the building plan by different persons who will be working on the construction. Not all possible electric symbols used on a certain plan, so the symbols used in the current home plan are included to a legend. The electrical home plan may be added as a separate document to a complete set of building plans.

While designing a conceptual data model, you should use appropriate software. For instance, ConceptDraw DIAGRAM is a user-friendly ER diagram tool that has a lot of samples and templates to facilitate your work. A clear entity-relationship diagram helps to define the relations between system’s components.
Software engineering is the section of a computer science engaged to design, realization, and support of complex software products. An ERD is a data modeling method that is widely applied in the software engineering practice. Commonly it is used for developing a structure of a a relational database. An entity relationship diagram is helpful for structuring and organizing databases that can be modeled using a relational structure. An entity relationship diagram is designed to depicts the interrelationships within the sets of entities which are accumulated in the database. Each entity represents a particular component of a data. Thus, ER diagrams depicts the logical structure of databases. ConceptDraw ER Diagrams solution provides software engineers with the professional tool for making entity-relationship diagrams.
