Model-driven application

Last updated

A model-driven application is a software application that the functions or behaviors are based on, or in control of, some evolutionary applied models of the target things to the application. The applied models are served as a part of the application system in which it can be changed at runtime. The target things are what the application deals with, such as the objects and affairs in business for a business application. Follows the definition of application in TOGAF, [1] a model-driven business application could be described as an IT system that supports business functions and services running on the models of the (things in) business.

History

The ideal of the architecture for a model-driven application was first put forward by Tong-Ying Yu on the Enterprise Engineering Forum in 1999, which have been studied and spread through some internet media for a long time. It had influence on the field of enterprise application development in China; there were successful cases of commercial development of enterprise/business applications in the architectural style of a model-driven application. [2] Gartner Group carried out some studies into the subject in 2008; they defined the model-driven packaged applications as "enterprise applications that have explicit metadata-driven models of the supported processes, data and relationships, and that generate runtime components through metadata models, either dynamically interpreted or compiled, rather than hardcoded." [3] The model-driven application architecture is one of few technology trends to driven the next generation of application modernization, that claimed by some industrial researchers in 2012. [4]

Hard coding is the software development practice of embedding data directly into the source code of a program or other executable object, as opposed to obtaining the data from external sources or generating it at run-time. Hard-coded data typically can only be modified by editing the source code and recompiling the executable, although it can be changed in memory or on disk using a debugger or hex editor. Data that are hard-coded usually represent unchanging pieces of information, such as physical constants, version numbers and static text elements. Softcoded data, on the other hand, encode arbitrary information like user input, HTTP server responses, or configuration files, and are determined at runtime.

Instance

Business process management (BPM) is the significant practice to the model-driven application. According to the definition, a BPM system is model-driven if the functions are operated based on the business process models which are built and changed at the operational time but not the design or implementation time; the biggest advantage is that it can deal with the continuous changing of business process directly without modifying the code of the software.

Business process management (BPM) is a discipline in operations management in which people use various methods to discover, model, analyze, measure, improve, optimize, and automate business processes. BPM focuses on improving corporate performance by managing business processes. Any combination of methods used to manage a company's business processes is BPM. Processes can be structured and repeatable or unstructured and variable. Though not required, enabling technologies are often used with BPM.

Notes

Note that it should be distinguished from the Model-Driven Architecture (MDA); the latter is a software design approach for the development of software systems and generally does not specify a specific system style or the runtime configuration.

Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model-driven architecture is a kind of domain engineering, and supports model-driven engineering of software systems. It was launched by the Object Management Group (OMG) in 2001.

Software design is the process by which an agent creates a specification of a software artifact, intended to accomplish goals, using a set of primitive components and subject to constraints. Software design may refer to either "all the activity involved in conceptualizing, framing, implementing, commissioning, and ultimately modifying complex systems" or "the activity following requirements specification and before programming, as ... [in] a stylized software engineering process."

A software system is a system on intercommunicating components based on software forming part of a computer system. It "consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system".

Business process automation (BPA), also known as business automation or digital transformation, is the technology-enabled automation of complex business processes. It can streamline a business for simplicity, achieve digital transformation, increase service quality, improve service delivery or contain costs. It consists of integrating applications, restructuring labor resources and using software applications throughout the organization. Robotic process automation is an emerging field within BPA and uses artificial intelligence.

Enterprise architecture (EA) is "a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes."

The Open Group Architecture Framework TOGAF

The Open Group Architecture Framework (TOGAF) is a framework for enterprise architecture that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. TOGAF is a high level approach to design. It is typically modeled at four levels: Business, Application, Data, and Technology. It relies heavily on modularization, standardization, and already existing, proven technologies and products.

A BRMS or business rule management system is a software system used to define, deploy, execute, monitor and maintain the variety and complexity of decision logic that is used by operational systems within an organization or enterprise. This logic, also referred to as business rules, includes policies, requirements, and conditional statements that are used to determine the tactical actions that take place in applications and systems.

Enterprise software, also known as enterprise application software (EAS), is computer software used to satisfy the needs of an organization rather than individual users. Such organizations include businesses, schools, interest-based user groups, clubs, charities, and governments. Enterprise software is an integral part of a (computer-based) information system.

Enterprise architecture framework frame in which the architecture of a company is defined

An enterprise architecture framework defines how to create and use an enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system. It structures architects' thinking by dividing the architecture description into domains, layers, or views, and offers models - typically matrices and diagrams - for documenting each view. This allows for making systemic design decisions on all the components of the system and making long-term decisions around new design requirements, sustainability, and support.

Knowledge Discovery Metamodel (KDM) is a publicly available specification from the Object Management Group (OMG). KDM is a common intermediate representation for existing software systems and their operating environments, that defines common metadata required for deep semantic integration of Application Lifecycle Management tools. KDM was designed as the OMG's foundation for software modernization, IT portfolio management and software assurance. KDM uses OMG's Meta-Object Facility to define an XMI interchange format between tools that work with existing software as well as an abstract interface (API) for the next-generation assurance and modernization tools. KDM standardizes existing approaches to knowledge discovery in software engineering artifacts, also known as software mining.
