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.Divided Bar Diagrams
Divided Bar Diagrams Solution extends the capabilities of ConceptDraw DIAGRAM with templates, samples, and a library of vector stencils for drawing high impact and professional Divided Bar Diagrams and Graphs, Bar Diagram Math, and Stacked Graph. Divided Bar Diagram library objects include a legend that describes categories and can be shown or hidden, moved into a diagram; some objects also include a table of input values for categories. Enter your data in the table, and the segments will be displayed on the chart in accordance with the table data; when you make changes, the chart changes automatically.
