UML Dotnet Streams
The Unified Modeling Language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure diagrams. The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. It was developed at Rational Software in 1994–1995, with further development led by them through 1996. In 1997, UML was adopted as a standard by the Object Management Group (OMG) and has been managed by this organization ever since. In 2005, UML was also published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as the ISO/IEC 19501 standard. Since then the standard has been periodically revised to cover the latest revision of UML. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modeling Language
A modeling language is any artificial language that can be used to express data, information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure of a programming language. Overview A modeling language can be graphical or textual. * ''Graphical'' modeling languages use a diagramming technique, diagram technique with named symbols that represent concepts and lines that connect the symbols and represent relationships and various other graphical notation to represent constraints. * ''Textual'' modeling languages may use standardized keywords accompanied by parameters or natural language terms and phrases to make computer-interpretable expressions. An example of a graphical modeling language and a corresponding textual modeling language is EXPRESS (data modeling language), EXPRESS. Not all modeling languages are executable, and for those that are, the use of them does ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivar Jacobson
Ivar Hjalmar Jacobson (; born September 2, 1939) is a Swedish computer scientist and software engineer, known as a major contributor to UML, Objectory, Rational Unified Process (RUP), aspect-oriented software development, and Essence. Biography Ivar Jacobson was born in Ystad, on September 2, 1939. He received his Master of Electrical Engineering degree at Chalmers Institute of Technology in Gothenburg in 1962. After his work at Ericsson, he formalized the language and method he had been working on in his PhD at the Royal Institute of Technology in Stockholm in 1985 on the thesis "Language Constructs for Large Real Time Systems". After his master's degree, Jacobson joined Ericsson and worked in R&D on computerized switching systems AKE and AXE including PLEX. In April 1987, he started Objective Systems. A majority stake of the company was acquired by Ericsson in 1991, and the company was renamed Objectory AB. Jacobson developed the software method Object-Oriented Sof ...

Object Constraint Language
The Object Constraint Language (OCL) is a declarative language describing rules applying to Unified Modeling Language (UML) models developed at IBM and is now part of the UML standard. Initially, OCL was merely a formal specification language extension for UML. OCL may now be used with any Meta-Object Facility (MOF) Object Management Group (OMG) meta-model, including UML. The Object Constraint Language is a precise text language that provides constraint and object query expressions on any MOF model or meta-model that cannot otherwise be expressed by diagrammatic notation. OCL is a key component of the new OMG standard recommendation for transforming models, the Queries/Views/Transformations ( QVT) specification. Description OCL is a descendant of Syntropy, a second-generation object-oriented analysis and design method. The OCL 1.4 definition specified a constraint language. In OCL 2.0, the definition has been extended to include general object query language definitions. OCL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Computer Society
The Australian Computer Society (ACS) is an association for information and communications technology professionals with 40,000+ members Australia-wide. According to its Constitution, its objectives are "to advance professional excellence in information technology" and "to promote the development of Australian information and communications technology resources". The ACS was formed on 1 January 1966 from five state based societies. It was formally incorporated in the Australian Capital Territory on 3 October 1967. Since 1983 there have been chapters in every state and territory. The ACS is a member of the Australian Council of Professions ("Professions Australia"), the peak body for professional associations in Australia. Internationally, ACS is a member of the International Professional Practice Partnership (IP3), South East Asia Regional Computer Confederation, International Federation for Information Processing and The Seoul Accord.

Merise
Merise () is a general-purpose modeling methodology in the field of information systems development, software engineering Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining Application software, software applications. It involves applying engineering design process, engineering principl ... and project management. First introduced in the early 1980s, it was widely used in France, and was developed and refined to the point where most large French governmental, commercial and industrial organizations had adopted it as their standard methodology. Merise proceeds to separate treatment of data and processes, where the data-oriented view is modelled in three stages, from conceptual, logical through to physical. Similarly, the process-oriented view passes through the three stages of conceptual, organizational and operational. These stages in the modelling process are paralleled by the stages of the li ...

Cardinality (data Modeling)
Within data modelling, cardinality is the numerical relationship between rows of one table and rows in another. Common cardinalities include ''one-to-one'', ''one-to-many'', and ''many-to-many''. Cardinality can be used to define data models as well as analyze entities within datasets. Relationships For example, consider a database of electronic health records. Such a database could contain tables like the following: * A doctor table with information about physicians. * A patient table for medical subjects undergoing treatment. * An appointment table with an entry for each hospital visit. Natural relationships exist between these entities: * A many-to-many relationship between records in doctor and records in patient because doctors have many patients and patients can see many doctors. * A one-to-many relationship between records in patient and records in appointment because patients can have many appointments and each appointment involves only one patient. * A one-to-one rela ...
