Structured Systems Analysis and Design Method (SSADM) with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method SSADM is the method which is used at projecting and analysis of information systems. SSADM is based on the data flow diagrams. At the description of data flows out of the system and into the system DFD, which denote boundaries of the system, are used.

JSD - Jackson system development

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 DIAGRAM software extended with Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park.

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

Flowchart Definition

Flowchart definition - A Flowchart is a graphically representation of the structure of process or system, algorithm or the step-by-step solution of the problem. The Flowchart describes the flow of data through an information processing systems and the parts of the flows. The flow is a set of the logic operations that meet the certain requirements.

Types of Flowcharts

A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types.

Data Flow Diagram

Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

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.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.

Pyramid Diagram

A three level pyramid model of different types of Information Systems based on the type of decisions taken at different levels in the organization.

Gane Sarson Diagram

The vector stencils library Gane-Sarson Notation from the solution Data Flow Diagrams contains specific symbols of the Gane-Sarson notation such as process symbol, connector symbol, jump symbol for ConceptDraw DIAGRAM diagramming and vector drawing software. The Data Flow Diagrams solution is contained in the Software Development area of ConceptDraw Solution Park.
