Enterprise Architecture is an organizational practice of analyzing, planning, designing and the implementation of enterprise solutions. Enterprise Architecture brings together the functions of information, business and application architects as well as the infrastructure specialization. Rationalization is the first basis for enterprise architecture. Rationalization process involves system consolidation to improve efficiency through cost-cutting. At Dell, there are five processes which are in relation to the enterprise architecture. These are outlined as Developing, marketing, selling, fulfilling and supporting. Each of the five processes is integrated with information technology. This is done to ensure the development of systems which are effective …show more content…
The ability of a reference architecture to provide guidance so that future developers understand how to program future applications in a domain is a primary motivation for the generation of a reference architecture. The guidance provided by a reference architecture can reduce development costs.
Another primary benefit of a reference architecture is to provide an understanding of the components of the architecture. This understanding allows users and developers to comprehend the implications of the architecture at a high level and also provides an understanding of the components that make up the architecture and the relationships between the components. A user community that desires to interchange components and to interoperate with systems requires such an understanding of the components. And therefore is a strong motivating force for the generation of reference architectures.
Since a reference architecture provides an understanding of a set of systems developed for a domain by generalizing and abstracting components and their inter-relationships, the creation of a reference architecture provides potential customers with a common perspective and principled basis for comparison of
Enterprise is an internationally known car rental, with more than “7,000 neighboring and airport locations throughout North America and Europe. Enterprise is the largest car rental brand in North America, well-known for its great rates, award-winning customer service and picking up local car rental customers at no extra cost” (About). Enterprise offers great leadership opportunities to its employees and helps them become entrepreneurs. They provide over 1 million job opportunities worldwide, this private company thrives its self in customer service because they thrive on being personable by creating relationships not just transactions
Adapt to externalities. Correct evaluation, however additional analysis is required. The IT department needs to collaborate with the business to better understand how organization changes impact applications and systems. Moreover, IT needs to strengthen the IT-business alignment to stay abreast of future changes. One methodology that may assist here is business architecture, a blueprint of the business that supports aligning strategic objectives and tactical demands.
Let us now examine a number of perspectives that should be considered when designing software solutions. In most cases, these perspectives will have direct consequences to the design of the user interface.
Different application types require the use of various development techniques for a number of reasons. The below are a few such reasons:
Stage 3 involves creating an Architectural Model version of the whole system including sub systems. A Viewpoint Hierarchy shows a skeleton version of the system which can be ins...
A framework is a set of classes that supports reuse at larger granularity. It defines an object-oriented abstract design for a particular kind of application which enables not only source code reuse, but also design reuse [Johnson & Foote, 1988]. The framework abstract structure can be filled with classes from its own library or application-specific ones, providing flexibility for the developer to adapt its behavior to each application. Besides flexibility, a good framework also increases the team productivity and makes application maintenance easier [Fayad et al. 1999].
Field of Dreams (1989) directed by Phil Alden Robinson is a glaringly idyllic rendition of the arguably overtaxed notion of "follow your dreams." While deeper themes such as faith and references to a nascent national mythology in the form of baseball were constants in the narrative, such concepts are easily overshadowed by the consistent attempt to specifically appeal toward the sentimentalities of the film's contemporaneous target audience. Besides this, Field of Dreams may have accomplished little beyond eliciting the fleeting goosebump and momentary bout of fondness from the lay viewer who exists only on the uttermost peripheral of the American pastime, or those who are hardly familiar with the history of baseball required to truly appreciate the exclusive
At the moment, Enterprise resources planning (ERP) systems had become important systems in the modern business world. The meaning of ERP itself is an integrated software package composed by a set of standard functional modules (production, sales, human resources, finance, etc.) developed or integrated by the vendor that can be adapted to the specific needs of each customer (Esteves et al. 2000).
are used as the integral components of the architectural design, this reflecting a conceptual cohesion that is missed in previous architecture.
Additionally, American Express architecture key components include using a standardized language and initiatives. Indeed, a standardize architecture has helped American Express improved the efficiency, maintenance for IT staff, and overall a consistent interface for clients. First, the key components of the architecture that American Express has created are reference architecture and road maps. According to InfoWorld (2011) “The EA practice has successfully addressed the needs of the business by delivering reference architectures and road maps that promote standardized application architectures, facilitate innovation, and enable rapid product development.”
Component Based Architecture creates a system that is easily extensible, promotes software reuse and intuitively understandable. A component often relates to an object in Object Orientated Programming. The RUP provides a systematic way to build this kind of system, focusing on producing an early executable architecture before committing full resources on a project.
Enterprise Resource Planning (ERP) systems integrate (or attempt to integrate) all data and processes of an organization into a unified system
“An Enterprise resource planning (ERP) systems are software systems for business management, supporting areas such as planning, manufacturing, sales, marketing, distribution, accounting, finance, human resource management, project management, inventory management, service and maintenance, transportation, and e-business”.( Haag, Cummings, Phillips, S, M, A (2007). Mangement Information Systems. New Yory, NY: The McGraw-Hill Company Inc..)
obect orientated programming has many advantages, one of these is the fact that the objects created : Jeffrey L. Popyack (2012) "can easily be reused in other programs." The Saylor Foundation also states that object orientated programming allows “Improved software-development productivity" and "Improved software maintainability” through the modular structure of the development.
There are many different ways to define an architecture as they can take many forms, including logical views, scenarios (or sequence diagrams), physical views and deployment views. Each view provides a specific type of information within the diagram and is directed to a certain audience, including Web architects, data architects, application architects and end users.
