Structured Systems Analysis and Design Method. SSADM with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method
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.

DFD Library System

DFD Library System *
The Data Flow Diagram (DFD) is a graphical technique used for effective modeling and analyzing the information processes and systems. Having at the disposal the DFD library system and newest powerful tools of ConceptDraw DIAGRAM diagramming and vector drawing software supplied with Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park, you can design fast and easy the Data flow diagrams, Data flowcharts, Data flow models, Data flow process diagrams, Process-oriented models, Data-oriented models, Data process diagrams, Structured analysis diagrams, Information flow diagrams of any type and complexity. For designing the Data Flow Diagrams in ConceptDraw DIAGRAM software are used the simple DFD flowchart symbols from the offered DFD libraries - Data Flow Diagram (DFD) library, Yourdon and Coad Notation library, and Gane-Sarson Notation library. The DFD objects are need to be connected each other by the arrows to depict the data flow from one step to another, that you can do in seconds in ConceptDraw DIAGRAM , as well as set desired design of your diagram.

Interface Design

Interface Design *
Website wireframes are convenient and widely used by developers, visual designers, business analysts, and many other people related with projection, development and promotion websites. Usually website wireframes look lacking of brilliance, but they effectively reflect website functionality, content and visually represent its skeletal framework. ConceptDraw DIAGRAM software offers a unique Website Wireframe solution from the Software Development area with all needed tools for fast and easy drawing professional looking website wireframe with attractive interface design.

Healthy Foods

Healthy Foods *
Use of various charts, diagrams and infographics is the most effective way of visual presenting information about healthy foods, healthy eating and healthy diet. ConceptDraw DIAGRAM diagramming and vector drawing software offers the Health Food solution from the Food and Beverage area of ConceptDraw Solution Park which is overfull of powerful drawing tools, libraries with ready-to-use vector objects and clipart, predesigned samples and examples which will help you easy design healthy foods illustrations.

The Jackson Structured Programming (JSP) Diagram solution extends the functionality and drawing abilities of the ConceptDraw DIAGRAM software with set of illustrative JSP diagrams samples and large variety of predesigned vector objects of actions, processes, procedures, selection, iteration, as well as arrows and connectors to join the objects during Jackson structured development and designing Jackson structured programming diagrams, JSP diagram, Jackson structure diagram (JSD), Program structure diagram. The powerful abilities of this solution make the ConceptDraw DIAGRAM ideal assistant for programmers, software developers, structural programmers, computer engineers, applications constructors, designers, specialists in structured programming and Jackson systems design, and other technical, computer and software specialists.

Types of Flowcharts

Types of Flowcharts *
A Flowchart is a graphical representation of process, algorithm, workflow or step-by-step solution of the problem. It shows the steps as boxes of various kinds and connects them by arrows in a defined order depicting a flow. There are twelve main Flowchart types: Basic Flowchart, Business Process Modeling Diagram (BPMN), Cross Functional Flowchart, Data Flow Diagram (DFD), IDEF (Integrated DEFinition) Flowchart, Event-driven Process Chain (EPC) Diagram, Influence Diagram (ID), Swimlane Flowchart, Process Flow Diagram (PFD), Specification and Description Language (SDL) Diagram, Value Stream Mapping, Workflow Diagram. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design a Flowchart of any of these types. This solution offers a lot of special predesigned vector symbols for each of these widely used notations. They will make the drawing process of Flowcharts much easier than ever. Pay also attention for the included collection of ready Flowchart examples, samples and quick-start templates. This is business process improvement tools. If you are looking for MS Visio for your Mac, then you are out of luck, because it hasn't been released yet. However, you can use Visio alternatives that can successfully replace its functions. ConceptDraw DIAGRAM is an alternative to MS Visio for Mac that provides powerful features and intuitive user interface for the same.

This purchase order processing UML activity diagram was created on the base of activity diagram from the software architecture documentation wiki of the Software Engineering Institute (SEI) of Carnegie Mellon University (CMU).

"A purchase order (PO) is a commercial document and first official offer issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services. Acceptance of a purchase order by a seller forms a contract between the buyer and seller, so no contract exists until the purchase order is accepted. It is used to control the purchasing of products and services from external suppliers.
Creating a purchase order is typically the first step of the purchase to pay process in an ERP system." [Purchase order. Wikipedia]
