Model Driven Architectures ( Soa )

Logical and physical models represent the key elements and processes of the software development. The logical model describes the processes, and data, in as much detail as possible, without giving regard to how the system will be implemented. Logical data models include

IT would like to spend more time on innovations and less time and on developing software. The SOA model has the ability to decrease IT budgets in several ways since the fundamental applications and technology to support an SOA are already in place with the development focus on integration and existing business logic remains viable cost on system maintenance. There would be no frequent upgrades and will not need to be re-architected or replaced to meet new business requirements.

Provides UML modelling for database designs, with the ability to represent the integration of data and application requirements through logical and physical designs

MVC architectural pattern is most extensively used by software architect designer, programmer and GUI developer while developing the user interactive applications. The MVC architectural pattern contains three types of architectural units or components: Model, View and Controller which actually separate the complete application logic to three logical units: business/entity (model), presentation (view) and control (controller). The model component contains business logic and application data, the view use to retrieve and show application data from/to user and the controller handle the user request/response through view and handle interaction between view and

Upon reviewing all of the service reusability is the stage of service oriented design that most affect the granularity that compose the software solution. I came to this conclusion, because reusability of a service grants it to have endless potential. Not only can a service be reused, it can perform different tasks.

According to Versace (2014), the Internet of the Twenty-First Century has opened up a whole new and exciting way for how one does business. With this paradigm shift of doing things differently, the effects are moving through “several business models forcing companies to adapt or be left behind” (Versace, 2014, p. 1). The expansion of the Internet and technological industry has no boundaries and caters to all ages. Versace (2014) stated, “several industries that have only just starting embracing the Internet, and one of them is the gambling and casino industry:” (para. 3). The online gaming business or iGaming, “has grown into a multi-billion-dollar business, particularly in Europe,” (Versace, 2008).

With the completion of the logical model, a physical model is outlined to portray the actual design of a database. Physical modeling illustrates the integration of the data requirements that were recognized during logical modeling into a system structure that will be implemented. A physical model creates objects using symbols such as tables and columns based on entities and attributes that were defined during logical modeling. Constraints, such as primary keys, foreign keys and other unique keys, are defined in this modeling phase. It is crucial to have a well-informed, knowledgeable design team in the development of the physical model. “To ensure that all information system needs are met, physical models are often developed jointly by a team representing the data administration, database administration, and application development areas” (CA ERwin Data Modeler Methods Guide – CA, n.d.). Physical modeling is database specific, which means the objects defined during physical modeling can vary depending on the database software being used. The hardware of a company

This thesis is written within the domain of modeled software development and engineering . Through the use of Modeling Language when developing modern computer systems gives the developers the feasibility of applying formal patterns and symbols in an object oriented analysis and design (OOA/D) environment. Model Driven Development (MDD) has, throughout the last years ago of tool and technology development, developed into a solution for developers giving them the ability to define a solution while creating artifacts that becomes part of the overall solution.

According IEEE Standards ISO/IEC/IEEE 42010, an architecture is defined as system fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution (ISO/IEC/IEEE 42010, 2011)

A design pattern solves a problem within a given context. The solution that is offered by implementing a pattern results in a system design structure, which balances the concerns of the design problem in a manner most appropriate for the given context. In “Understanding and Using Patterns in Software Development”, Dirk Riehle and Heinz Zullighaven offer a rather nice definition of what a design pattern is:

New imperatives and technologies are forcing companies to rethink their fundamental business assumptions. The C-suite is under pressure to perform at increasingly high speeds and scale - there’s no letting up. Today’s executives are turning to cloud-based solutions to help improve business efficiencies while reducing CAPEX. Executives are immersed in terms like software as a service, open source, big data, cloud, scale-out, containers, microservices etc. While these terms and technologies represent a new world of opportunity, they also bring complexity that most IT departments are ill-equipped to pursue. This has become the Big Software era.

The list of adopted technologies in OMG include (UML) in 1997, Model Driven Architecture (MDA), System Modelling Language (SysML) and Business Process Modelling Notation (BPMN) in 2006. The OMG’ architecture objective are to give a benefit application developers by making it easier for developers in building a large-scale, industrial strength applications through standard components. In making decision especially in meeting, they are a few OMG committees that involved which is Architecture Board, various Task Forces, Subcommittees, Platform, Special Interest Groups and Domain Technical Committees.

A key requirement of the software design of a computer-based system is to transform basic requirements into an architecture that describes the software 's top-level structure and identifies its components. Accomplishment of this requirement is through architectural design, providing a blueprint for developing the framework of the software (Mattsson, Lundell, Lings, & Fitzgerald, 2009). The establishment of the framework involves examining the software requirements document and designing a model for providing necessary implementation details. The details specify components of the system along with all inputs, outputs, functions, and the interactions between the components. This paper includes a description of the architectural design of a computer-based system that has transform characteristics, and includes a data flow diagram with process narrative, and evaluation of the architectural design. Further, an assessment of the structuring requirements associated with software architecture is included.

In use of large applications there is information silos, where information cannot be shared between different applications/software’s. Integrating systems can solve this problem of information silos, but integrating systems often involve a huge cost. Service Orientated Architecture provides free flow of information, where different applications and systems can share and exchange information.. This saves integration cost. The other benefits of integration with SOA are

Also, there has been exponential growth due to the increase in number of software systems being described as object-oriented. Many programming languages, office information systems, system simulation and artificial intelligence have adopted object-oriented technology. It is an assumption that learns specific development method or a set of tools.
