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.

Cisco Network Design. Cisco icons, shapes, stencils, symbols and design elements

Cisco is the largest company, which specializes in the field of high technologies, develops and sells network equipment mainly for the large organizations and telecommunication companies. Cisco produces wide variety of devices and equipment, such as routers, switches, gateways, servers, network security devices (firewalls, VPN, IDs, etc.), ATM switches, cable modems and DSL equipment, access points Wi-Fi, products for IP telephony, etc. The first commercially successful multi-protocol router, which enabled for previously incompatible computers to communicate between themselves, is also developed by Cisco company. Cisco is a generally accepted standard, which uses globally recognized Cisco icons for all produced Cisco equipment. ConceptDraw DIAGRAM software extended with Cisco Network Diagrams solution from Computer and Network area contains a lot of predesigned Cisco network design elements for professional drawing Cisco network diagrams, visualization computer network topologies, equipment connections and arrangement.

Netflow architecture. Computer and Network Examples

Netflow is a network protocol used for accounting the IP network traffic. It was developed by Cisco Systems. Now it is actually the industrial standard, it is supported by many devices. There are several versions of the protocol, but the most common are the versions 5 and 9. This diagram was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Netflow architecture.

Landscape Plan

A landscape plan depicts all the features of a future garden including buildings, plants, lawns or a patio. Such plan is a very important part of site adjustment because it gives a complete picture of future project.
