Unreferenced stub auto yes date December 2009 Object oriented modeling OOM , also called object oriented programming OOP is a modeling paradigm mainly used in computer programming . Prior to the rise of OOM, the dominant paradigm was procedural programming , which emphasized the use of discrete reusable code blocks that could stand on their own, take variables, perform a function on them, and return values. The object oriented paradigm assists the programmer to address the complexity of a problem domain by considering the problem not as a set of functions that can be performed but primarily as a set of related, interacting Objects. The modeling task then is specifying, for a specific context, those Objects or the Class the Objects belongs to , their respective set of Properties and Methods, shared by all Objects members of the Class. For more discussion, see object oriented analysis and design and object oriented programming . The description of these objects is a Logical schema schema . As an example, in a model of a Payroll System , a Company is an Object. An Employee is another Object. Employment is a Relationship or Association. An Employee Class or Object for simplicity has Attributes like Name, Birthdate, etc. The Association itself may be considered as an Object, having Attributes, or Qualifiers like Position, etc. An Employee Method may be Promote, Raise, etc. The Model description or Schema may grow in complexity to require a Notation. Many notations have been proposed, based on different paradigms, diverged, and converged in a more popular one known as Unified Modeling Language UML . An informal description or a Schema notation is translated by the programmer or a computer aided software engineering CASE tool in the case of Schema notation created using a Module specific to the CASE tool application into a specific programming language that supports object oriented ... .

ObjectModeling Language is a modeling language based on a standardized set of symbols and ways of arranging them to model part of an object orientation object oriented software design or system design . Some organizations use them extensively in combination with a software development methodology to progress from initial specification to an implementation plan and to communicate that plan to an entire team of developers and stakeholders. Because a modeling language is visual and at a higher level of abstraction than code, using models encourages the generation of a shared vision that may prevent problems of differing interpretation later in development. Often software modeling tools are used to construct these models, which may then be capable of automatic translation to code. History Some methodologies identify three roughly chronological generations of objectmodeling notations first , second and third generation . First generation In the first generation , isolated methodologists and small groups developed techniques that solved problems they saw first hand in Object Oriented OO development projects. The first generation includes techniques such as Booch method Class responsibility collaboration card CRC Objectmodeling technique OMT Object oriented software engineering OOSE Shlaer Mellor Yourdon Coad see Edward Yourdon The first generation languages were co developed and very closely tied with specific object oriented methodologies usually with the same name. It was often difficult to determine whether the notation or methodology was being referred to.

Unreferenced date December 2009 In computer science, Actor modeling is a form of software modeling , which focuses on software actors . Actor modeling is most prominently used for the early modeling of requirements through this it becomes possible to understand who the users and Project stakeholder stakeholders of a system are and what their interests and needs are regarding that system . The increasing complexity of today s systems makes it more appropriate to take this approach, instead of a traditional, more mechanically focused approach. When thinking along the dimensions of users and their needs, it is easier to comprehend what the system is designed to accomplish. This approach furthermore helps the users to define the requirements for the system. The approach of actor modeling is normally combined with the modeling of goals and tasks to give a better understanding of the situation the user is in. There are different modeling language s that support actor modeling examples include i and EEML . The Actor The central entity of the Actor modeling the actor itself can be any kind of entity that is performing action s . It may for example be a person, a department, or an organization.

Unreferenced date December 2009 ERP modeling , abbreviated to ERP , is the process of reverse engineering an Enterprise Resource Planning software package in order to align it to an organizational structure. Usage Although ERP modeling could possibly be performed by several methodologies, this entry deals with ERP modeling using Object Process Methodology , or OPM. OPM appears to be a usable methodology for modeling ERP systems, as the methodology focuses on optionality within objects and processes of an ERP system. ERP modeling is done by analyzing the optionality within an ERP system to identify the different functions of the system that the end using company needs, regarding its organizational structure. Reverse engineering both ERP system and organizational structure to the same level of granularity makes both layers compatible for aligning the package in the organization. ERP breaks down traditional functional barriers by facilitating data sharing, information flows, and the introduction of common business practices among all organizational users. Theory A Global Business Process Model is created which represents the whole ERP software product. This model is layered in 3 deeper levels. The first level is the System Configuration Level , which scopes on high level optionality on the entire system. Option definition is therefore static once a high level option of the ERP system ... is the Object Level , which scopes on single data objects.

Unreferenced date October 2009 Inappropriate tone date December 2007 An Object graph is a view of an object system at a particular point in time. Whereas a normal data model such as a Unified Modeling Language UML Class diagram details the relationships between classes, the object graph relates their instances. Object diagram s are subsets of the overall object graph. Object oriented applications contain complex webs of interrelated objects. Objects are linked to each other by one object either owning or containing another object or holding a reference to another object. This web of objects is called an object graph and it is the more abstract structure that can be used in discussing an application s state. Physical representation An object graph is a directed graph , which might be Cycle graph cyclic . When stored in Random access memory RAM , objects occupy different segments of the memory with their attributes and function table, while relationships are represented by pointer computer programming pointer s or a different type of global handler in higher level languages.

Visual modeling is the graphic representation of objects and systems of interest using graphical language s. Visual modeling languages may be General Purpose Modeling GPM languages e.g., Unified Modeling Language UML , Southbeach Notation , IDEF or Domain Specific Modeling DSM languages e.g., SysML . They include industry open standards e.g., UML, SysML , as well as proprietary standards, such as the visual languages associated with VisSim , MATLAB and Simulink , OPNET , and NI Multisim . VisSim is unique in that it provides a royalty free, downloadable Viewer that lets anyone open and interactively simulate VisSim models. Visual modeling languages are an area of active research that continues to evolve, as evidenced by increasing interest in DSM languages, visual requirements , and visual OWL Web Ontology Language . ref name faq cite web author title Visual OWL url http www.visualmodeling.com VisualOWL.htm ref See also Service oriented modeling Discipline specific modeling Discipline Specific Modeling Domain Specific Modeling Model Driven Engineering Modeling language References reflist External links http www.VisualModelingForum.com Visual Modeling Forum A web community dedicated to visual modeling languages and tools.

Knowledge modeling is a process of creating a computer interpretable model of knowledge or standard specifications about a kind of process and or about a kind of facility or product. The resulting knowledge model can only be computer interpretable when it is expressed in some knowledge representation language or data structure that enables the knowledge to be interpreted by software and to be stored in a database or data exchange file. br Knowledge based engineering or knowledge aided design is a process of computer aided usage of such knowledge models for the design of products, facilities or processes. The design of products or facilities then uses the knowledge model to guide the creation of the facility or product that need to be designed. In other words it used knowledge about a kind of object to create a product model of an imaginary individual object. Similarly, the design of a particular process implies the creation of a process model, which design activity can be guided by the knowledge that is contained in a knowledge model about such a kind of process. The resulting process model, product model or facility model is typically also stored in a database. Usually the knowledge representation language only allows to represent knowledge about kinds of things , whereas another language or data structure is required to represent and store the information models about individual things. If the knowledge representation language enables to express both, then the knowledge model ... English .
