Structured Systems Analysis and Design Method. SSADM with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (SSADM) was developed in the UK in the early 1980s and accepted in 1993 in order to analyze and project the information systems. Use the data flow diagrams (DFD) for describing the informational, functional and event-trigger models, the Logical Data Structure (LDS) diagrams for describing which data the system operates with and Entity Life History (ELH) diagrams for modelling events that happened in the system and find it simple to make any of these or other diagrams with help of our software. Starting now, you’ll definitely make a better chart tomorrow, so why not to do it now, at this very moment? Once you get used to ConceptDraw DIAGRAM , you’ll find our product to be the most smart version of any existing applications and you’ll recommend it to all those who you care for to simplify their work and their lives.

Entity Relationship Diagram Examples

Create an Entity-Relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.

ConceptDraw DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram(ERD) solution from the Software Development area supplies the ConceptDraw DIAGRAM with icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

UML Use Case Diagram Example. Registration System

The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.

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 SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

Account Flowchart Stockbridge System. Flowchart Examples

Create your own flow charts of data processing systems using the ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Cross-Functional Flowcharts solution from the Business Processes area of ConceptDraw Solution Park.
This is a flowchart of a data processing system combining manual and computerized processing to handle accounts receivable, billing, and general ledger.

Flowchart Programming Project. Flowchart Examples

Flowcharts can be used in designing and documenting both simple and complex processes or programs and, similar to the other types of diagrams, they can help visualize what happens and so help understand some definite process, and, as a result, find flaws, bottlenecks and other features within it.

System Design

ConceptDraw DIAGRAM system design software is a product of CS Odessa that was developed especially for making it much simpler to create all the needed diagrams, charts, flowcharts, schemes and other drawings when there is such a need in it. Having the Specification and Description Language (SDL) solution installed from the ConceptDraw STORE application may be another bonus to any ConceptDraw DIAGRAM diagramming and drawing software’s user as it offers both stencil libraries with the design elements and the pre-made examples of the diagrams, such as the SDL ones.

Taxi Service Data Flow Diagram DFD Example

This sample shows the Data Flow Diagram of the Taxi Service and interactions between the Clients, Operators and Divers, as well as Orders and Reports databases.

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.
