Structured Systems Analysis and Design Method (SSADM) with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior. Applying of SSADM is easy with ConceptDraw DIAGRAM diagramming and vector drawing software and Data Flow Diagram solution.

Block Diagram

The vector stencils libraries: Block Diagrams, Blocks with Perspective, Callouts, Connectors, Raised Blocks from the solution Block Diagrams contain specific block diagram symbols such as arrows, input/output symbols, start/end symbols, processing symbols, conditional symbols, commenting symbols, callouts, connectors, etc. for ConceptDraw DIAGRAM diagramming and vector drawing software. The Block Diagrams solution is contained in a "Diagrams" area of ConceptDraw Solution Park. Use the libraries from the Block Diagrams solution to draw block diagrams for your business documents, presentations and websites in a few minutes.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.

Hybrid Network Topology

A network topology is the topological structure or the arrangement of different elements of computer network. There are several basic types of network topologies, such as star, ring, bus, mesh. But the most popular is a combination of two or more diverse basic network topologies, which is known as hybrid network topology. The examples of hybrid topology are: star-bus, star-ring topologies, etc. Each resulting hybrid topology has its own features, advantages and limitations of its components. Hybrid network topologies are more flexible, reliable, and have increased fault tolerance, the faults in them can be easily diagnosed and corrected, new nodes can be easily added. But at the same time hybrid topologies often are sufficiently expensive and difficult for managing. ConceptDraw DIAGRAM diagramming and vector drawing software supplied with the tools of Computer Network Diagrams solution from Computer and Networks area is perfect for schematic description various types of computer network topologies and easy designing Hybrid network topology diagrams.

ConceptDraw Arrows10 Technology

Imagine the diagram which is looking smart. That is how ConceptDraw Arrows10 Technology or Smart connectors work. Thanks to auto-routing feature connectors flow around objects. But if you want some background objects that the connectors flow through - that is also possible to do.

Star Network Topology

Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful. The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

UML Tool & UML Diagram Examples

The Unified Modeling Language (abbr. UML) is a general-purpose modeling language widely used in the field of software development, software engineering, education, science, industry, business. In 1997 the UML was approved as a standard by the OMG (Object Management Group) and in 2005 was published as ISO standard by the International Organization for Standardization. UML is widely and succesfully applied for optimization the process of software systems development and business systems analysis. There are used 14 types of UML diagrams, 7 from them depict structural information, another 7 types represent different types of behavior and aspects of interactions. Design of any automated process is easy with ConceptDraw DIAGRAM and unique Rapid UML solution from the Software Development area, which provides numerous UML examples, templates and vector stencils libraries for drawing all types of UML 1.x and UML 2.x diagrams. Use of predesigned UML diagram examples and templates lets you quickly start drawing your own UML diagrams in ConceptDraw DIAGRAM software.

Active Directory Diagram

Active Directory (AD) is a directory management service introduced by Microsoft Corporation for Windows domain networks. This service uses the Lightweight Directory Access Protocol (LDAP) and provides quick access to the included information about large structural units such as domains, organizational units, sites, and also about simple objects, such as users names with detailed information about them - contacts information, access rights, etc. Active Directory Diagram is a representation of the network structure in clear graphical format. It is a scheme of correlations of service components with preset degree of detailed elaboration. Active Directory Diagram makes the work of network administrators with Active Directory network structure more easy and convenient, allows plan and service the network quicker and more qualitatively. The help of ConceptDraw DIAGRAM software extended with Active Directory Diagrams solution from the Computer and Networks area is indispensable for easily and quickly creation the highly detailed Active Directory Diagrams.
