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.

Program Evaluation and Review Technique (PERT) with ConceptDraw DIAGRAM

Program Evaluation and Review Technique (abbr. PERT) is a method developed by Ministry of Defense of the USA in 1958 for the project of creation the missile system Polaris. PERT diagram is one of the tools for project management that lets greatly simplify the planning and scheduling of large and complex projects. PERT diagram provides evaluation of project run-time and labor forces, it helps to analyze the time necessary for execution each of project tasks and the whole project, and to calculate the project critical path. PERT chart depicts the set of tasks connected each other in order of their execution and is constructed according to one of definite rules - AOA (activity on arrow) or AON (activity on node). It doesn't give you ready concrete decisions, but helps to find them. Design easy the PERT diagrams in ConceptDraw DIAGRAM software enhanced with Seven Management and Planning Tools solution from Management area of ConceptDraw Solution Park. You have a possibility to build the PERT chart of any type, but AON variant is easier for building and perception.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.

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.

IDEF0 Flowchart Symbols

The modeling of business and business processes is not quite a simple process for both small-size businesses and large businesses. The IDEF0 method is one of the popular and easy methods of modeling the business as a complex system. It is based on the functional modeling language Structured Analysis and Design Technique (abbr. SADT) and is concentrated on the activity modeling. According to this method are constructed the IDEF0 Diagrams and IDEF0 Flowcharts, which are succesfully used not only for documenting the business, but also for analysis, development, integration of information and software systems, reengineering, etc. This method suggests the use of special IDEF0 Flowchart Symbols from the IDEF0 notation for construction the IDEF0 Flowcharts. ConceptDraw DIAGRAM diagramming and vector graphic software extended with IDEF0 Diagrams solution from the Software Development area of ConceptDraw Solution Park is rich for the powerful drawing tools, built-in templates and samples, and predesigned IDEF0 flowchart symbols.

How to Create Gantt Chart

To begin managing a new project, you will need to define the individual Tasks that must be completed to deliver it. The default view for a new project in ConceptDraw PROJECT is the Gantt Chart.

Data Flow Diagrams

The information system manages the flow of data introduced into the system. To graphically represent and document the flow of data through some information system is used a Data Flow Diagram (DFD). DFD is a way to visualize the flow of data or data processing, to clearly demonstrate what type of data or information is transferred, where they come from and where are sent. It lets to create an overview of the system, to depict the major steps, and effectively model the processes. DFDs are helpful for analyzing and modifying the business systems. Traditionally are used two notations for DFDs creation - Yourdon-Coad and Gane-Sarson. ConceptDraw DIAGRAM software offers a special Data Flow Diagrams solution from Software Development area, which enables to quickly and simply create professional Data Flow Diagrams including the data storage, data flows, external entities, functional transforms, control transforms and signals. Use the offered templates, samples and extensive range of libraries to design your own Data Flow Diagrams in minutes.

Data Flow Diagram Software

Data Flow Diagrams (DFDs) are successfully used when studying the business processes or systems that involve the transfer of data. They are a visual way to represent the data processing, to model and visualize the flow of data through a computer system and functional requirements for a designed system. They are the good business modeling tool to describe the business events and interactions, the physical systems involving the storage and transfer of data. ConceptDraw DIAGRAM supplied with Data Flow Diagrams solution from Software Development area of ConceptDraw Solution Park is a modern and powerful data flow diagram software.

ConceptDraw DIAGRAM is a powerful tool that helps you create professional looking cross-functional flowcharts with the well-designed objects. ConceptDraw DIAGRAM - Drawing Software for Vertical Cross Functional Flowchart. ConceptDraw allows you to focus on work, not the drawing process. ConceptDraw Arrows10 Technology allows to draw connectors with smart behavior that gives flexibility to you during work process.

ConceptDraw Arrows10 Technology

When using a shapes′ center connection the connection becomes dynamic, the connector will trace the contour of the object, when moving the object inside your diagram. Using any other connection point provides a static connection, when you move connected objects the connector stays attached to the same point.
