Node (UML)
A node in the Unified Modeling Language (UML) is a computational resource upon which artifact (UML), UML artifacts may be deployed for execution. OMG (2008). OMG Unified Modeling Language (OMG UML), Superstructure, V2.1.2'' p.199-210. 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 Artifact (UML), UML artifacts may be deployed for execution. Devices may be complex (i.e., they may consist of other devices). * An execution environment represents software containers (such as operating systems, JVM, servlet/EJB containers, application servers, portal servers, etc.) This is a node that offers an execution environment for specific types of components that are deployed on it in the form of deployable artifacts. Execution environments can be nested. Nodes can be interconnected through communication paths to define network structures. A ''commun ...

Nodes
In general, a node is a localized swelling (a "knot") or a point of intersection (a Vertex (graph theory), vertex). Node may refer to: In mathematics *Vertex (graph theory), a vertex in a mathematical graph *Vertex (geometry), a point where two or more curves, lines, or edges meet. *Node (autonomous system), behaviour for an ordinary differential equation near a critical point *Singular point of an algebraic variety#Nodes, Singular point of an algebraic variety, a type of singular point of a curve In science and engineering Astronomy *Orbital node, the points where an orbit crosses a plane of reference ** Lunar node, where the orbits of the sun and moon intersect ** Longitude of the ascending node, how orbital nodes are parameterized Biology *Lymph node, an immune system organ used to store white blood cells *Node of Ranvier, periodic gaps in the insulating myelin sheaths of myelinated axons *Sinoatrial node and atrioventricular node, specialized tissues in the heart responsibl ...

Unified Modeling Language
The Unified Modeling Language (UML) is a general-purpose, developmental modeling language in the field of software engineering that is intended to provide a standard way to visualize the design of a system. 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) as an approved ISO standard. Since then the standard has been periodically revised to cover the latest revision of UML. In software engineering, most practitioners do not use UML, but instead produce informal hand drawn diagrams; these diagrams, however, often include elements from UML. History Before UML 1 ...

Artifact (UML)
An artifact in the Unified Modeling Language (UML) is the specification of a physical piece of information that is used or produced by a software development process, or by deployment and operation of a system."OMG (2008). OMG Unified Modeling Language (OMG UML), Superstructure, V2.1.2'' p.197. Examples of artifacts include model files, source files, scripts, and binary executable files, a table in a database system, a development deliverable, a word-processing document, or a mail message. Artifacts are the physical entities that are deployed on Nodes (i.e. Devices and Execution Environments). Other UML elements such as classes and components are first manifested into artifacts and instances of these artifacts are then deployed. Artifacts can also be composed of other artifacts. See also * Artifact (software development) An artifact is one of many kinds of ''tangible'' by-products produced during the development of software. Some artifacts (e.g., use cases, class diagrams, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Container
OS-level virtualization is an operating system (OS) paradigm in which the kernel allows the existence of multiple isolated user space instances, called ''containers'' ( LXC, Solaris containers, Docker, Podman), ''zones'' (Solaris containers), ''virtual private servers'' (OpenVZ), ''partitions'', ''virtual environments'' (VEs), ''virtual kernels'' (DragonFly BSD), or ''jails'' (FreeBSD jail or chroot jail). Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, network shares, CPU power, quantifiable hardware capabilities) of that computer. However, programs running inside of a container can only see the container's contents and devices assigned to the container. On Unix-like operating systems, this feature can be seen as an advanced implementation of the standard chroot mechanism, which changes the apparent root folder ...
