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.
A package in the Unified Modeling Language is used "to group elements, and to provide a namespace for the grouped elements". [1] A package may contain other packages, thus providing for a hierarchical organization of packages. Pretty much all UML elements can be grouped into packages. Thus, classes, objects, use cases, components, nodes, node ...
In object oriented programming, the factory method pattern is a creational pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact class. Rather than by calling a constructor, this is done by calling a factory method to create an object. Factory methods can either be specified in an ...
Astah*. Astah, formerly known as JUDE ( Java and UML Developers' Environment, pronounced Jūdo (ジュード) ), is a UML modeling tool created by Japanese company Change Vision. JUDE received the "Software Product Of The Year 2006" prize, established by Information-Technology Promotion Agency in Japan. [1]
Node (UML) A node in the Unified Modeling Language (UML) is a computational resource upon which UML artifacts may be deployed for execution. [1] There are two types of nodes: device nodes and execution environments . A device represents hardware devices: a physical computational resource with processing capability upon which UML artifacts may ...
A context model (or context modeling) defines how context data are structured and maintained (It plays a key role in supporting efficient context management). [1] It aims to produce a formal or semi-formal description of the context information that is present in a context-aware system. In other words, the context is the surrounding element for ...
A UML tool is a software application that supports some or all of the notation and semantics associated with the Unified Modeling Language ( UML ), which is the industry standard general-purpose modeling language for software engineering . UML tool is used broadly here to include application programs which are not exclusively focused on UML ...
Umple. Umple is a language for both object-oriented programming and modelling with class diagrams and state diagrams . The name Umple is a portmanteau of "UML", "ample" and "Simple", [1] indicating that it is designed to provide ample features to extend programming languages with UML capabilities.
