In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. The class diagram is the main building block of object-oriented modeling.
Entity–relationship model. An entity–attribute-relationship diagram for an MMORPG using Chen's notation. An entity–relationship model (or ER model) describes interrelated things of interest in a specific domain of knowledge. A basic ER model is composed of entity types (which classify the things of interest) and specifies relationships ...
System context diagram. Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram .
UML logo. 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.
SysML diagrams collage. The systems modeling language ( SysML) [1] is a general-purpose modeling language for systems engineering applications. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems . SysML was originally developed by an open source specification project ...
In class-based programming, objects are created as instances of classes by subroutines called constructors, and destroyed by destructors. An object is an instance of a class as it can access to all data types (primitive as well as non primitive), and methods etc., of a class. Therefore, objects may be called a class instances or class objects.
Online learning involves courses offered by primary institutions that are 100% virtual. Online learning, or virtual classes offered over the internet, is contrasted with traditional courses taken in a brick-and-mortar school building. It is a development in distance education that expanded in the 1990s with the spread of the commercial Internet ...
NClass supports only class diagram of the standard UML diagram types. The user interface is designed to be simple and user friendly, and the visualization of diagrams is configurable via a style system. NClass can generate source code from the model or reverse engineer .NET assemblies by a plugin written by Malte Ried.
