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.

Network Topology Graphical Examples

Computer and Networks solution provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment. This example of computer network topology diagram shows home WLAN equipment and their connection to the Internet.

ConceptDraw DIAGRAM Compatibility with MS Visio

The powerful diagramming and business graphics tools are now not exception, but the norm for today’s business, which develop in incredibly quick temp. But with the abundance of powerful business diagramming applications it is important to provide their compatibility for effective exchange the information between the colleagues and other people who maybe use different software in their work. During many years Microsoft Visio™ was standard file format for the business and now many people need the visual communication software tools that can read the Visio format files and also export to Visio format. The powerful diagramming and vector drawing software ConceptDraw DIAGRAM is ideal from the point of view of compatibility with MS Visio. Any ConceptDraw DIAGRAM user who have the colleagues that use MS Visio or any who migrates from Visio to ConceptDraw DIAGRAM , will not have any problems. The VSDX (Visio′s open XML file format) and VDX formatted files can be easily imported and exported by ConceptDraw DIAGRAM , you can see video about this possibility.

Software Work Flow Process in Project Management with Diagram

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Workflow Diagrams Solution from the Software Development area of ConceptDraw Solution Park.

This sample shows the Workflow Diagram that clearly illustrates stages a BPM consists of and relations between all parts of business. The Workflow Diagrams are used to represent the transferring of data during the work process, to study and analysis the working processes, and to optimize a workflow.

Wireless Network WAN

Wireless Networks solution from ConceptDraw Solution Park extends ConceptDraw DIAGRAM diagramming and vector drawing software to help network engineers and designers efficiently design, create and illustrate WAN network diagram of any complexity. The ConceptDraw DIAGRAM software helps users to quickly transit from an idea to the implementation of a Wireless Network WAN

Definition Flowchart

A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This definition flowchart gives a clear answer for the question "What is a flowchart?". It is convenient to use a powerful ConceptDraw DIAGRAM software extended with Flowcharts Solution from the "Diagrams" Area of ConceptDraw Solution Park to design flowcharts of various types which will additionally illustrate a definition flowchart.

Marketing Analysis Diagram

An example of marketing analysis diagram, can be used to analyse product market and define marketing strategy. This types of charts used by small business project management for making presentations on market shares, it used by marketing project management software and project management tracking tools for reporting results and statuses.

Fishbone Diagram Problem Solving

The Ishikawa diagram, Cause and Effect diagram, Fishbone diagram — all they are the names of one and the same visual method for working with causal connections. Originally invented by Kaoru Ishikawa to control the process quality, the Ishikawa diagram is well proven in other fields of management and personal scheduling, events planning, time management. It is a chart in the form of a fish, whose head is a problem, the fins are variants for its causes. To design easily the Fishbone diagram, you can use a special ConceptDraw DIAGRAM ector graphic and diagramming software which contains the powerful tools for Fishbone diagram problem solving offered by Fishbone Diagrams solution for the Management area of ConceptDraw Solution Park.

Data Flow Diagram

Data Flow Diagram (DFD) is the part of the Structured Systems Analysis and Design Methodology (SSADM), which is intended for information systems projection and analysis. Data Flow Diagrams allow graphically represent the data flows in information system and analyze the data processing during the structural projection. This type of diagrams lets visually show a work of information system and results of this work, it is often used in connection with human processes and can be displayed as Workflow diagram. Data Flow Diagram visualizes processes and functions, external entities, data depositories, and data flows connecting these elements and indicating direction and data character. Each of these elements used for DFD has its own graphical notation. There are two notations to draw DFDs - Yourdon & Coad and Gane & Sarson. ConceptDraw DIAGRAM extended with Data Flow Diagrams (DFD) solution from Software Developmant area is ideal for designing professional looking DFDs, which can be then easily exported in various formats.

Software Diagrams

Modern software development begins with designing different software diagrams and also uses a large amount of diagrams in project management and creation graphic documentation. Very popular diagrams that depict a work of applications in various cuts and notations, describe databases and prototype Graphical User Interfaces (GUIs). Software engineering specialists and software designers prefer to use special technical and business graphics tools and applications for easy creation diagrams. One of the most popular is ConceptDraw DIAGRAM diagramming and vector drawing software. ConceptDraw DIAGRAM offers the possibility of drawing with use of wide range of pre-drawn shapes and smart connectors, which allow to focus not on the process of drawing, but on the task's essence. It is a perfect application for design and document development, planning tasks, visualization of data, design the databases, object-oriented design, creation flowcharts of algorithms, modeling business processes, project management, automation of management and development processes, and for many other tasks.
