Structured Systems Analysis and Design Method. SSADM with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (SSADM) was developed in the UK in the early 1980s and accepted in 1993 in order to analyze and project the information systems. Use the data flow diagrams (DFD) for describing the informational, functional and event-trigger models, the Logical Data Structure (LDS) diagrams for describing which data the system operates with and Entity Life History (ELH) diagrams for modelling events that happened in the system and find it simple to make any of these or other diagrams with help of our software. Starting now, you’ll definitely make a better chart tomorrow, so why not to do it now, at this very moment? Once you get used to ConceptDraw DIAGRAM , you’ll find our product to be the most smart version of any existing applications and you’ll recommend it to all those who you care for to simplify their work and their lives.

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.

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.

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.

Competitor Analysis

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.

Data Flow Diagram Examples

You need to draw the Data Flow Diagram? Use ConceptDraw DIAGRAM diagramming and vector drawing software extended with Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.The Data Flow Diagrams solution provides a numerous collection of Data Flow Diagram examples created according to Gane and Sarson, and Yourdon and Coad notations using the ConceptDraw DIAGRAM software.

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.

Program Structure Diagram

A visual representation of the configuration system, as well as the internal interfaces among such drawing’s CIs, may be always done with the help of the professional tool, such as the ConceptDraw DIAGRAM diagramming software. The structure diagram may be used for identifying the CIs as well as their associated artifacts. Doing it with the aid of ConceptDraw DIAGRAM as well as its extension (the Jackson Structured Programming (JSP) Diagrams solution) may simplify anyone’s work of making such diagrams.

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.

Software and Database Design with ConceptDraw DIAGRAM

ConceptDraw DIAGRAM is a perfect tool for designing and planning tasks such as:
UML diagramming; designing and prototyping Graphical User Interface (GUI); flowcharts, data flow diagrams; database and ERD diagramming (Chen ERD, Database Model diagram, Express-G, Martin ERD, ORM Diagrams and more); SSADM diagrams, Booch diagrams, Nassi-Shneiderman diagrams with special flowchart symbols.
