SSADM Diagram

The vector stencils library SSADM from the solution Systems engineering contains specific symbols of SSADM diagrams for ConceptDraw DIAGRAM diagramming and vector drawing software. The Systems engineering solution is contained in Software Development area of ConceptDraw Solution Park. The example below illustrates the waterfall model used in SSADM. This model involves 5 stages of developing a product such as requirements specification and its' analysis, design, coding and testing.

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.

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.

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.

ORM Diagram

The vector stencils library ORM Diagrams from the solution Software Development contains specific ORM symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Software Development solution is contained in the ConceptDraw Solution Park.
