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 DIAGRAM software extended with Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park.

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 DIAGRAM 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.

Jacobson Use Cases Diagram

The vector stencils library UML Use Case contains specific symbols of the UML notation such as actors, actions, associations and relationships for the ConceptDraw DIAGRAM diagramming and vector drawing software. This library is contained in the Rapid UML solution from Software Development area of ConceptDraw Solution Park.

SDL Diagram

Specification and Description Language (SDL) is used for creating the object-oriented diagrams, visualizing the processes of the state machines for the systems of communication, telecommunication, automotive, aviation and medical industries. SDL is a specification language for creating specifications, descriptions of the behavior, data, and inheritance for real-time systems. This sample shows the SDL Diagram of the process game.

Agile Methodology

Agile methodology is an excellent alternative to waterfall and traditional sequential development. ConceptDraw DIAGRAM software extended with SCRUM Workflow solution is ideal for quick and easy designing various diagrams, charts, mind maps and schematics illustrating software development using Agile methodologies, and in particular Scrum methodology.

Jackson Structured Programming (JSP) Diagrams

The Jackson Structured Programming (JSP) Diagram solution extends the functionality and drawing abilities of the ConceptDraw DIAGRAM software with set of illustrative JSP diagrams samples and large variety of predesigned vector objects of actions, processes, procedures, selection, iteration, as well as arrows and connectors to join the objects during Jackson structured development and designing Jackson structured programming diagrams, JSP diagram, Jackson structure diagram (JSD), Program structure diagram. The powerful abilities of this solution make the ConceptDraw DIAGRAM ideal assistant for programmers, software developers, structural programmers, computer engineers, applications constructors, designers, specialists in structured programming and Jackson systems design, and other technical, computer and software specialists.

Jackson Systems

Entity structure diagram (ESD) notations may be created in the ConceptDraw DIAGRAM same as any other diagram, including a Jackson Structured Programming (JSP) Diagram. Having the Jackson Structured Programming (JSP) Diagrams solution may simplify the work of drawing the needed illustration representing the given data within only a few minutes. Having the pre-made examples of the JSP diagrams, any ConceptDraw DIAGRAM user is able to make his own unique as well as smart looking drawing in a fun and entertaining way.

Business Process Flow Diagram

Business Process Flow Diagram is a graphical presentation of business processes and process flows. It is one of the main tool of business analysis and business process re-engineering that lets identify and easy understand process flows within organization. ConceptDraw DIAGRAM extended with Business Process Workflow Diagrams solution from the Business Processes area of ConceptDraw Solution Park is a powerful software which lets easy design Business Process Flow Diagram of any complexity.

Software Development Area

Solutions from the Software Development Area of ConceptDraw Solution Park collect templates, samples and libraries of vector stencils for drawing the software engineering diagrams and user interface design prototypes.

Employee ORM diagram

This object-role modeling (ORM) diagram sample shows model of employee data: birthdate, hiredate, rank, company car number. It was designed on the base of the Wikimedia Commons file: ORM-diagram-tkz-orm.png. [commons.wikimedia.org/ wiki/ File:ORM-diagram-tkz-orm.png]
"Facts.
Object-role models are based on elementary facts, and expressed in diagrams that can be verbalised into natural language. ...
This "fact-based" approach facilitates modeling, transforming, and querying information from any domain. ...
Attribute-free.
ORM is attribute-free: unlike models in the entity–relationship (ER) and Unified Modeling Language (UML) methods, ORM treats all elementary facts as relationships and so treats decisions for grouping facts into structures (e.g. attribute-based entity types, classes, relation schemes, XML schemas) as implementation concerns irrelevant to semantics. By avoiding attributes in the base model, ORM improves semantic stability and enables verbalization into natural language. ...
Fact-based modeling.
Fact-based modeling includes procedures for mapping facts to attribute-based structures, such as those of ER or UML. ...
Fact-based graphical notations are more expressive than those of ER and UML. ...
Design procedure.
System development typically involves several stages such as: feasibility study; requirements analysis; conceptual design of data and operations; logical design; external design; prototyping; internal design and implementation; testing and validation; and maintenance." [Object-role modeling. Wikipedia]
The object-role modeling diagram example "Employee ORM diagram" was designed using ConceptDraw PRO software extended with ORM Diagrams solution from Software Development area of ConceptDraw PRO Solution Park.
