MetaCASE
A metaCASE tool is a type of application software that provides the possibility to create one or more modeling methods, languages or notations for use within the process of software development. Often the result is a modeling tool for that language. MetaCASE tools are thus a kind of language workbench, generally considered as being focused on graphical modeling languages. Another definition: ''MetaCASE tools'' are software tools that support the design and generation of CASE tools. In general, metaCASE tools should provide generic CASE tool components that can be customised and instantiated into particular CASE tools. The intent of metaCASE tools is to capture the specification of the required CASE tool and then generate the tool from the specification. Overview Quick CASE tools overview Building large-scale software applications is very complicated process which is not easy to handle. Software companies must have good system of cooperation throughout developing teams and good di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Generic Modeling Environment
Generic Modeling Environment (GME) is a model-integrated program synthesis tool for creating domain-specific models of large-scale systems. GME allows users to define new modeling languages using UML-based metamodels. GME was developed by the Institute for Software Integrated Systems at Vanderbilt University. GME is a part of the META Tool Suite and the Adaptive Vehicle Make program. The main language it uses is CyPhyML. The new version of GME, called WebGME, is entirely web-browser based. It supports simultaneous distributed collaborative editing of models and has a version controlled database backend in the cloud.

Database Schema
The database schema is the structure of a database described in a formal language supported by the database management system (DBMS). The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases). The formal definition of a database schema is a set of formulas (sentences) called integrity constraints imposed on a database. These integrity constraints ensure compatibility between parts of the schema. All constraints are expressible in the same language. A database can be considered a structure in realization of the database language. The states of a created conceptual schema are transformed into an explicit mapping, the database schema. This describes how real-world entities are modeled in the database. "A database schema specifies, based on the database administrator's knowledge of possible applications, the facts that can enter the database, or those of interest to the ...

MetaDONE
MetaDONE is a software environment for creating domain-specific modeling languages (DSML). MetaDONE is developed by the PReCISE Research Center of the University of Namur (Belgium). It supports multi-level modeling and is fully bootstrapped. User-defined languages can have several concrete notations that are defined declaratively with the GraSyLa language. This framework proposes several modeling languages (Business Process Model and Notation (BPMN), User Requirements Notation (URN), Goal-oriented Requirements Language (GRL), Petri Net A Petri net, also known as a place/transition (PT) net, is one of several mathematical modeling languages for the description of distributed systems. It is a class of discrete event dynamic system. A Petri net is a directed bipartite graph that ...) that can be freely customized by the users.

MetaEdit+
MetaEdit+ is an environment for creating and using Domain-Specific Modeling languages. Research History The research behind the genesis of MetaEdit+ was carried out at the University of Jyväskylä, as part of the MetaPHOR project. A metamodeling and modeling tool, MetaEdit, had been created by the earlier SYTI project in the late 1980s and early 1990s, in co-operation with a company, MetaCase. Both MetaEdit and MetaEdit+ were described in a large number opublications from the MetaPHOR research group(including,). Tool History MetaEdit allowed graphical metamodeling using Object-Property-Role-Relationship (OPRR) data model, definition of the DSM language notation with a graphical symbol editor, and the definition of code generators using a Domain-Specific Language. These three elements together formed a metamodel file, which configured MetaEdit to support that modeling language. * MetaEdit 1.0 was released as shareware in 1993. * MetaEdit 1.1 was released as commercial softw ...

Object Oriented Programming Language
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with impera ...

Object (computer Science)
In computer science, an object can be a variable, a data structure, a function, or a method. As regions of memory, they contain value and are referenced by identifiers. In the object-oriented programming paradigm, ''object'' can be a combination of variables, functions, and data structures; in particular in class-based variations of the paradigm it refers to a particular instance of a class. In the relational model of database management, an object can be a table or column, or an association between data and a database entity (such as relating a person's age to a specific person). Object-based languages An important distinction in programming languages is the difference between an object-oriented language and an object-based language. A language is usually considered object-based if it includes the basic capabilities for an object: identity, properties, and attributes. A language is considered object-oriented if it is object-based and also has the capability of polymorphism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XML Metadata Interchange
The XML Metadata Interchange (XMI) is an Object Management Group (OMG) standard for exchanging metadata information via Extensible Markup Language (XML). It can be used for any metadata whose metamodel can be expressed in Meta-Object Facility (MOF). The most common use of XMI is as an interchange format for UML models, although it can also be used for serialization of models of other languages (metamodels). Overview In the OMG vision of modeling, data is split into abstract models and concrete models. The abstract models represent the semantic information, whereas the concrete models represent visual diagrams. Abstract models are instances of arbitrary MOF-based modeling languages such as UML or SysML. For diagrams, the Diagram Interchange (DI, XMI I standard is used. There are currently several incompatibilities between different modeling tool vendor implementations of XMI, even between interchange of abstract model data. The usage of Diagram Interchange is almost nonex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class (computer Science)
In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods). In many languages, the class name is used as the name for the class (the template itself), the name for the default constructor of the class (a subroutine that creates objects), and as the type of objects generated by instantiating the class; these distinct concepts are easily conflated. Although, to the point of conflation, one could argue that is a feature inherent in a language because of its polymorphic nature and why these languages are so powerful, dynamic and adaptable for use compared to languages without polymorphism present. Thus they can model dynamic systems (i.e. the real world, machine learning, AI) more easily. When an object is created by a constructor of the class, the resulting object is called an instance of the class, and the member variabl ...
