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.

Entity Relationship Diagram Examples

Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database. ConceptDraw DIAGRAM professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity.

UML Use Case Diagram Example. Registration System

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park. This sample shows the types of user’s interactions with the system and is used at the registration and working with the database system.

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.

Account Flowchart Stockbridge System. Flowchart Examples

Graphical User Interface Examples

ConceptDraw DIAGRAM extended with Windows 8 User Interface solution from the Software Development area is the best gui software. Using the drawing tools, libraries of vector objects, graphical user interface examples that offers Windows 8 User Interface solution, you will easily design the Windows 8 user interfaces and Windows 8 UI design patterns of any complexity.

Material Requisition Flowchart. Flowchart Examples

Material requisition is a request generated by internal or external organization with a goal to inform the purchase department about the needed items and materials. The requisition can be represented as a written document on a pre-printed form or online request in form of electronic document. The electronic inquisition occupies a leading position in a modern world, now the paper forms are replaced by electronic ordering processes and workflows. The requisition is actively used in business as an internal document for notification the store about the needed goods, in medicine for making the orders on medical equipment and medicaments, in industry for creation request for purchasing some items and materials, and so on. ConceptDraw DIAGRAM ector graphics software extended with Flowcharts solution from the Diagrams area is powerful and useful tool for drawing various types of Flowcharts, including without doubt the Material Requisition Flowchart of any degree of detailing. Succeed in drawing using the large quantity of predesigned flowchart specific shapes, symbols and icons.
