Structured Systems Analysis and Design Method (SSADM) with ConceptDraw PRO
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."Data flow diagrams are one of the three essential perspectives of the structured-systems analysis and design method SSADM. The sponsor of a project and the end users will need to be briefed and consulted throughout all stages of a system's evolution. With a data flow diagram, users are able to visualize how the system will operate, what the system will accomplish, and how the system will be implemented. The old system's dataflow diagrams can be drawn up and compared with the new system's data flow diagrams to draw comparisons to implement a more efficient system. Data flow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to dispatch to report. How any system is developed can be determined through a data flow diagram model.
In the course of developing a set of levelled data flow diagrams the analyst/ designers is forced to address how the system may be decomposed into component sub-systems, and to identify the transaction data in the data model.
Data flow diagrams can be used in both Analysis and Design phase of the SDLC.
There are different notations to draw data flow diagrams (Yourdon & Coad and Gane & Sarson), defining different visual representations for processes, data stores, data flow, and external entities." [Data flow diagram. Wikipedia]
The DFD (Yourdon and Coad notation) example "Process of account receivable" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

Process Flowchart
ConceptDraw is Professional business process mapping software for making process flow diagram, workflow diagram, general flowcharts and technical illustrations for business documents. It is includes rich examples, templates, process flowchart symbols. ConceptDraw flowchart maker allows you to easier create a process flowchart. Use a variety of drawing tools, smart connectors, flowchart symbols and shape libraries to create flowcharts of complex processes, process flow diagrams, procedures and information exchange.Example of DFD for Online Store (Data Flow Diagram) DFD Example
Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.
IDEF9 Standard
Use Case Diagrams technology. An effective management of changes is significantly facilitated by way of definition and documenting of business-requirements.What Is Information Architecture
What is information architecture? Information architecture (IA) is a broad and abstract term. At the most general sense the information architecture describes the structure of a system, how the different pieces of information are related at the system and represents their relationships. The information architecture term was introduced by Richard Saul Wurman in 1975 and now is commonly used in the context of websites and intranets, information structures and computer systems.ConceptDraw PRO extended with Enterprise Architecture Diagrams Solution from the Management Area is the best software for design information architecture and drawing Enterprise Architecture Diagrams.
