What is a Local Area Network?

Examples of LAN Diagrams

Local Area Network (LAN) is a network which consists of computers and peripheral devices connected each other and to the local domain server, and covers a little territory or small number of buildings, such as home, school, laboratory, office, etc. LAN serves for few hundreds of users. It includes many cables and wires, and demands to design previously a Network diagram. All local area network devices can use the shared printers and disk storage. ConceptDraw DIAGRAM is a perfect network diagramming software with examples of LAN Diagrams, templates and predesigned vector objects. ConceptDraw DIAGRAM is the ideal choice for network engineers and network designers who need to draw fast and easy Local Area Network Diagrams, for IT specialists, developers and other IT professionals which need to visualize the communication schemes of LAN and visually document the LAN's physical structure and arrangement in houses, offices and other buildings. Ready-to-use vector objects from Computer Network Diagrams solution will help you design LAN diagrams in minutes.

UML component diagram - Template

"Component diagram shows components, provided and required interfaces, ports, and relationships between them. This type of diagrams is used in Component-Based Development (CBD) to describe systems with Service-Oriented Architecture (SOA).
Component-based development is based on assumptions that previously constructed components could be reused and that components could be replaced by some other "equivalent" or "conformant" components, if needed.
The artifacts that implement component are intended to be capable of being deployed and re-deployed independently, for instance to update an existing system.
Components in UML could represent:
(1) logical components (e.g., business components, process components), and
(2) physical components (e.g., CORBA components, EJB components, COM+ and .NET components, WSDL components, etc.),
along with the artifacts that implement them and the nodes on which they are deployed and executed. It is anticipated that profiles based around components will be developed for specific component technologies and associated hardware and software environments."

The template "UML component diagram" for the ConceptDraw PRO diagramming and vector drawing software is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.

Design elements - Bank UML deployment diagram

The vector stencils library "Bank UML deployment diagram" contains 10 shapes for drawing UML deployment diagrams.
Use it for object-oriented modeling of your bank information system.
"A deployment diagram in the Unified Modeling Language models the physical deployment of artifacts on nodes. To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts") run on each node (e.g., web application, database), and how the different pieces are connected (e.g. JDBC, REST, RMI).
The nodes appear as boxes, and the artifacts allocated to each node appear as rectangles within the boxes. Nodes may have subnodes, which appear as nested boxes. A single node in a deployment diagram may conceptually represent multiple physical nodes, such as a cluster of database servers.
There are two types of Nodes:
1. Device Node.
2. Execution Environment Node.
Device nodes are physical computing resources with processing memory and services to execute software, such as typical computers or mobile phones. An execution environment node (EEN) is a software computing resource that runs within an outer node and which itself provides a service to host and execute other executable software elements."

Design Element: Chen for Entity Relationship Diagram - ERD

Design Element: Chen <br>for Entity Relationship Diagram - ERD *

Entity-Relationship Diagrams (ERDs) were developed and introduced as a convenient and visual tool for the data modeling, they are the perfect way for easy determining data and also relationships between them. The first standard notation for ERD was proposed by Chen. Chen's notation is very rich on the data modeling tools and standard notation symbols and elements for drawing easy understandable Entity-relationship diagrams, Attribute diagrams, Decomposition charts, which are especially popular for designing relational databases. The entity is the main term, it is a set of instances abstract or real objects with common characteristics or attributes. Any system's object is represented by one uniquely identified entity, relationships describe the links between the entities. ConceptDraw DIAGRAM diagramming software, which includes the Entity-Relationship Diagram (ERD) solution, offers all needed tools for professional drawing ER diagrams. Specially developed vector ERD design elements according to Chen and Crow's Foot notations are indispensible for professional ERDs design.

Data Flow Diagram (DFD)

A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design. The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations.
