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 PRO diagramming and vector drawing software and Data Flow Diagram solution.
The vector stencils library SSADM from the solution Systems engineering contains specific symbols of SSADM diagrams for ConceptDraw PRO 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.
Jackson System Development (JSD) is a linear method of system development created by Michael A. Jackson and John Cameron in the 1980s. It comprises the whole software life cycle directly or providing a framework for more specialized techniques.
When implementing the Jackson System Development method and designing JSD diagrams, you can succesfully use the powerful and helpful tools of ConceptDraw PRO software extended with Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park.
Pyramid diagram is a chart used to visualize the data in a hierarchical (pyramid-like) structure and depict the foundation-based relationships. Pyramid diagram looks like a triangle divided by lines into several sections (layers) and can be oriented up or down, and represented in 2D or 3D view. 2D Pyramid diagrams are a great way to illustrate the hierarchical structure, 3D Pyramids are equally good to represent the class stratification and hierarchy.
ConceptDraw PRO diagramming and vector drawing software with included Pyramid Diagrams solution from Marketing area of ConceptDraw Solution Park is a powerful application which contains templates and library of vector design elements for instantly drawing three level Pyramid model, four level and five level Triangle charts. All predesigned objects are easy for changing color style and resizing according to your needs, and ConceptDraw documents with Pyramid diagrams can be easy exported in various formats for further using in marketing presentations, for effective analyzing hierarchy levels and illustration your data and ideas.
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 PRO 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.
Workflow Diagram created by using special software based on graphic mastering technology Arrows10. Its automatics follows the global concept of business graphics and diagramming. The practical effectiveness of Arrows10 technology used in ConceptDraw PRO are around the quick auto-arrows behaving as expected and connecting boxes of workflow diagram from workflow symbol to process flow symbol.
ConceptDraw PRO is a workflow diagram software contains specific features help you to draw diagrams faster, such as RapidDraw, or Arrows10. There is also a rich set of samples and templates to give you an example of data may be visualized as workflow diagram.
Competitor analysis is a first and obligatory step in elaboration the proper corporate marketing strategy and creating sustainable competitive advantage. Use powerful opportunities of numerous solutions from ConceptDraw Solution Park for designing illustrative diagrams, charts, matrices which are necessary for effective competitor analysis.
Flowchart definition - A Flowchart is a diagram that graphically represents the structure of the system, the flow of steps in a process, algorithm, or the sequence of steps and decisions for execution a process or solution a problem. For depiction the steps there are used specific shapes and graphic symbols which are linked by lines and directional arrows. The main standard shapes are rectangle or box, rounded box, diamond, circle. A Flowchart is a convenient way to observe the follow the process from beginning to end, it lets improve the work of process, highlight the key elements and detach not essential or even excessive steps. The Flowcharts can represent different levels of detail: High-Level Flowchart, Detailed Flowchart, and Deployment or Matrix Flowchart. They are incredibly useful for programmers when developing the programs of any complexity and on any high level language.
Create your own Flowcharts using the ConceptDraw PRO diagramming and vector drawing software and powerful tools of Flowcharts solution from "Diagrams" area.
Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw PRO.
The main reason of using Process Flowchart or PFD is to show relations between major parts of the system. Process Flowcharts are used in process engineering and chemical industry where there is a requirement of depicting relationships between major components only and not include minor parts. Process Flowcharts for single unit or multiple units differ in their structure and implementation.

Drawing charts, diagrams, and network layouts has long been the monopoly of Microsoft Visio, making Mac users to struggle when needing such visio alternative like visio for mac, it requires only to view features, make a minor edit to, or print a diagram or chart. Thankfully to MS Visio alternative like ConceptDraw PRO software, this is cross-platform charting and business process management tool, now visio alternative for making sort of visio diagram is not a problem anymore however many people still name it business process visio tools.
