MetaCASE Tool
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 d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Development Process
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming. A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" is a particular instance as adopted by a specific organization. For example, many specific software development processe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Database Schema
The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term "wikt:schema, 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 Data modeling, modeled in the database. "A database schema specifies, based on the database administrator's knowledge of possible applications, the facts that can ent ...

ConceptBase
ConceptBase (a.k.a. ConceptBase.cc) is a deductive and object-oriented database management system developed at University of Skövde. Earlier development was done at University of Passau (1987-1992), University of Aachen (1992-2003), and University of Tilburg (1997-2013). It is mainly used for conceptual modeling and metamodeling in the domain of software engineering and related domains. ConceptBase.cc is free and open-source software. ConceptBase combines the following features: * Object-oriented concepts such as classes and inheritance * Deductive rules evaluated by a Datalog engine * Active rules conforming to the event condition action (ECA) paradigm * Recursive function definitions * Metamodeling A metamodel is a model of a model, and metamodeling is the process of generating such metamodels. Thus metamodeling or meta-modeling is the analysis, construction, and development of the frames, rules, constraints, models, and theories applica ... with arbitrarily many abstract ...

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 net (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 t ...) 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 ...

Generic Modeling Environment
The Generic Modeling Environment (GME) is a domain-specific, model-integrated program synthesis tool for creating domain-specific models of large-scale systems. GME development started in 2000 at Vanderbilt University, US and continues well into 2022. Initially it only supported MS Windows OS, but later evolved into WebGME, a web- and Node.js- based software. Its primary purpose is model-building. Overview GME allows users to define new modeling languages using UML-based metamodels. GME was developed in 2000 by the Institute for Software Integrated Systems at Vanderbilt University Vanderbilt University (informally Vandy or VU) is a private university, private research university in Nashville, Tennessee, United States. Founded in 1873, it was named in honor of shipping and railroad magnate Cornelius Vanderbilt, who provide .... GME is a part of the META Tool Suite and the Adaptive Vehicle Make program.

Object Oriented Programming Language
Object-oriented programming (OOP) is a programming paradigm based on the concept of ''objects''. Objects can contain data (called fields, attributes or properties) and have actions they can perform (called procedures or methods and implemented in code). In OOP, computer programs are designed by making them out of objects that interact with one another. Many of the most widely used programming languages (such as C++, Java, and Python) support object-oriented programming to a greater or lesser degree, typically as part of multiple paradigms in combination with others such as imperative programming and declarative programming. Significant object-oriented languages include Ada, ActionScript, C++, Common Lisp, C#, Dart, Eiffel, Fortran 2003, Haxe, Java, JavaScript, Kotlin, Logo, MATLAB, Objective-C, Object Pascal, Perl, PHP, Python, R, Raku, Ruby, Scala, SIMSCRIPT, Simula, Smalltalk, Swift, Vala and Visual Basic.NET.

Object (computer Science)
In software development, an object is an entity that has state, behavior, and identity. An object can model some part of reality or can be an invention of the design process whose collaborations with other such objects serve as the mechanisms that provide some higher-level behavior. Put another way, an object represents an individual, identifiable item, unit, or entity, either real or abstract, with a well-defined role in the problem domain. A programming language can be classified based on its support for objects. A language that provides an encapsulation construct for state, behavior, and identity is classified as object-based. If the language also provides polymorphism and inheritance it is classified as object-oriented. A language that supports creating an object from a class is classified as class-based. A language that supports object creation via a template object is classified as prototype-based. The concept of object is used in many different software contexts, ...

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), a platform-independent model (PIM). 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 ...

Class (computer Science)
In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state ( variables) and behavior ( methods) that are each either associated with a particular object or with all objects of that class. Object state can differ between each instance of the class whereas the class state is shared by all of them. The object methods include access to the object state (via an implicit or explicit parameter that references the object) whereas class methods do not. If the language supports inheritance, a class can be defined based on another class with all of its state and behavior plus additional state and behavior that further specializes the class. The specialized class is a ''sub-class'', and the class it is based on is its ''superclass''. Attributes Object lifecycle As an instance of a class, an object is constructed from a class via '' ...
