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.

Why Flowchart Important to Accounting Information System?

The Accounting flowchart shows how information flows from source documents through the accounting records. The are based on the accounting procedures or processes. Flowcharts are used to represent accounting information in a system. There are special symbols which are used to create accounting flowcharts. Try conceptdraw flowcharting set of symbols to draw a professional charts.

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

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.

Flowchart Definition

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 DIAGRAM diagramming and vector drawing software and powerful tools of Flowcharts solution from "Diagrams" area.

Network Topology Graphical Examples

Computer and Networks solution provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment. This example of computer network topology diagram shows home WLAN equipment and their connection to the Internet.

Lean Six Sigma Diagram Software

Lean Six Sigma (LSS) is a well-known in all over the world methodology of quality improvement and business perfection. ConceptDraw DIAGRAM diagramming and vector drawing software is a powerful Lean Six Sigma Diagram Software thanks to the included Value Stream Mapping solution from the Quality Management Area of ConceptDraw Solution Park.

Fishbone Diagram Problem Solving

The Ishikawa diagram, Cause and Effect diagram, Fishbone diagram — all they are the names of one and the same visual method for working with causal connections. Originally invented by Kaoru Ishikawa to control the process quality, the Ishikawa diagram is well proven in other fields of management and personal scheduling, events planning, time management. It is a chart in the form of a fish, whose head is a problem, the fins are variants for its causes. To design easily the Fishbone diagram, you can use a special ConceptDraw DIAGRAM ector graphic and diagramming software which contains the powerful tools for Fishbone diagram problem solving offered by Fishbone Diagrams solution for the Management area of ConceptDraw Solution Park.

Context Diagram Template

This template shows the Context Diagram. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Block Diagrams Solution from the “Diagrams” area of ConceptDraw Solution Park. The context diagram graphically identifies the system. external factors, and relations between them. It’s a high level view of the system. The context diagrams are widely used in software engineering and systems engineering for designing the systems that process the information.

Concept Maps

As concept map consists from conception-blocks and links between them, you can use ConceptDraw library objects and add to a document as much objects as you need. ConceptDraw tools let you to edit, group, move objects, change their appearance and add text signs and raster or vector pictures. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Concept Maps Solution from the "Diagrams" Area is effective tool for creating professional looking Concept Maps.
