Systems development life cycle

This circular arrows diagram sample shows the systems development life cycle (SDLC) stages.
"The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system. The systems development life-cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both." [Systems development life-cycle. Wikipedia]
The arrow circle diagram example "Systems development life cycle" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park. Read more

Process Flowchart

The main reason of using Process Flowchart or PFD is to show relations between major parts of the system. Process Flowcharts are used in process engineering and chemical industry where there is a requirement of depicting relationships between major components only and not include minor parts. Process Flowcharts for single unit or multiple units differ in their structure and implementation. ConceptDraw PRO is Professional business process mapping software for making Process flowcharts, Process flow diagram, Workflow diagram, flowcharts and technical illustrations for business documents and also comprehensive visio for mac application. Easier define and document basic work and data flows, financial, production and quality management processes to increase efficiency of your business with ConcepDraw PRO. Business process mapping software with Flowchart Maker ConceptDraw PRO includes extensive drawing tools, rich examples and templates, process flowchart symbols and shape libraries, smart connectors that allow you create the flowcharts of complex processes, process flow diagrams, procedures and information exchange. Process Flowchart Solution is project management workflow tools which is part ConceptDraw Project marketing project management software. Drawing charts, diagrams, and network layouts has long been the monopoly of Microsoft Visio, making Mac users to struggle when needing such visio alternative like visio for mac, it requires only to view features, make a minor edit to, or print a diagram or chart. Thankfully to MS Visio alternative like ConceptDraw PRO software, this is cross-platform charting and business process management tool, now visio alternative for making sort of visio diagram is not a problem anymore however many people still name it business process visio tools.

JSD - Jackson system development

Jackson System Development (JSD) is a linear method of system development created by Michael A. Jackson and John Cameron in the 1980s. It comprises the whole software life cycle directly or providing a framework for more specialized techniques. When implementing the Jackson System Development method and designing JSD diagrams, you can succesfully use the powerful and helpful tools of ConceptDraw PRO software extended with Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw PRO

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 PRO diagramming and vector drawing software and Data Flow Diagram solution. Read more

How to Draw ER Diagrams

An Entity Relationship (ER) Diagram is a type of flowchart that illustrates the logical structure of databases, how the different entities, such as people, objects or concepts relate to each other within a given system. How to draw ER Diagrams fast and easy? ConceptDraw PRO diagramming and vector drawing software enhanced with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park offers you the powerful abilities of designing the ER Diagrams and ERD drawings without efforts. This solution includes a lot of predesigned icons advocated by popular Chen's and Crow’s Foot notations, which can be used when describing an enterprise database and depicting it by abstract way. Simply drag the required objects to ConceptDraw document, connect them in a desired way and make style settings. But the easiest and fastest way of drawing ERDs is to make them on the base of ready-to-use Chen ERD and Crow's Foot ERD templates, which are both represented at ConceptDraw STORE. Read more

Data Flow Diagram (DFD)

A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design. The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations.
