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.
ConceptDraw DIAGRAM diagramming and vector drawing software extended with Fishbone Diagrams solution is a perfect tool for software designers and software developers. If you need to create Cause and Effect diagram, Fishbone diagram, Ishikawa diagram from templates and examples, or using the predesigned elements, ConceptDraw DIAGRAM can do this easily.
ConceptDraw DIAGRAM software gives ability to design Fishbone diagrams that identify many possible causes for an effect for problem. Each Fishbone diagram design element included to Fishbone Diagrams library is vector and ready-to-use.
ER-model is a data model which lets describe the conceptual schemes in a specific subject area. It can help to highlight the key entities and specify relationships that can be established between these entities. During the database design, it is realized the transformation of ER model into certain database scheme based on the chosen data model (relational, object, network, etc.). There are used two notations for ERDs: Crow's Foot and Chen's.
Crow's Foot notation proposed by Gordon Everest represents the entity by rectangle containing its name (name must be unique within this model), and relation - by the line which links two entities involved in relationship. The relationship's plurality is graphically indicated by a "plug" on the end of the link, the optionality - by a circle. Entity-Relationship Diagrams based on Crow's Foot notation can be easily drawn using the ConceptDraw DIAGRAM. Extended with Entity-Relationship Diagram (ERD) solution, it is the best ERD diagrams software with powerful tools and ready design elements for Crow's Foot and Chen notations.
When designing a process or an instruction in clear and understandable way, you should consider creating a flowchart. You can avoid spending a lot of time understanding complex concepts as they get clear with different diagrams. The flowcharts are very popular diagram type, they are useful at different fields from the description business processes to the presentation of cooking recipes. Basic Flowchart, Business Process Modeling Diagram, Process Flowchart, Cross Functional Flowchart, Procedure Flowchart, Data Flow Diagram, IDEF Flowchart, SDL Diagram, Workflow Diagram, Document Flowchart, Program Flowchart, Value Stream Map, System Flowchart, Highlight Flowchart, Sales Flowchart are the main types flowchart.
The ConceptDraw DIAGRAM is one of the professional applications which has great advantages and using which you can create different types of Flowcharts easy and fast. Try to draw an illustrative and comprehensible diagram in ConceptDraw DIAGRAM describing the processes instead of writing complex long text and make sure how it is convenient.
Visio is expensive, and if you use it in a team environment, these costs are compounded. ConceptDraw DIAGRAM is an affordable alternative to Visio and luckily, it comes with a team plan. ConceptDraw DIAGRAM can import and export Visio files, so Mac users can collaborate with PC users stuck on Microsoft's software.
UML Component Diagram Online Shopping. This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Component Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the concept of the online shopping and is used for the understanding of the online shopping processes, of the online shops working processes, for projection and creating of the online stores.
Office design must to be well thought-out. It is especially important for the small offices, where each detail is in sight. ConceptDraw DIAGRAM software offers you the Office Layout Plans Solution from the Building Plans Area for quick and easy creating detailed Small Office Design plans.
Use Case Diagrams technology. An effective management of changes is significantly facilitated by way of definition and documenting of business-requirements.
Network Topology in communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical topology.
Network Topology Mapper offers extensive drawing tools professional-looking network diagrams quickly and easily allowing you to clearly represent and communicate network architecture, topology, and design to engineers, stakeholders and end-users.
