Enterprise information architecture (EIA) is a process of describing a set of requirements, principles and models, and offering the current and future state guidance necessary for flexibly sharing and exchanging information required to achieve effective enterprise change (Bert & Wegner, 2009).
The component model is the integral part of Enterprise Information Architect. It describes the functional components with their roles and responsibilities, relationships and interactions with other components as well as what is required to enable implementation of specific deployment and customer use case scenarios.
Each Component is an independent part of the EIA, and focuses on the Component Relationship Diagram and Component Interaction Diagrams.
The physical model is described as a small or larger physical copy of an object. The model makes it possible for internal invisible parts to be easily seen. It provides a detailed description of how and where the components will be deployed and on what servers they will be deployed all across the system.
It covers implementation specific details used to represent the database and logical model, and represents the implementation of nonspecific data requirements (Schmitz, 2004).
The logic model is an organized and illustrative way to share and present a company’s understanding of the resources it is using for programs, the activities of the plan and the expected results. The various activities likely to bring about change within this model are presented through the use of pictures.
It brings the program’s concepts and dreams to life, and also provides stakeholders with a roadmap describing the sequence of events connecting the need for the planned program with the expected results. In this case, the model helps in picturing out how programs will function.
The model requires an organized method of planning and implementation of programs. It helps in creating a shared understanding of, and focuses on, programs goals and methodology relating activities to the projected outcome (Schmitz, 2004). The model is an effective measure of a program’s success.
The logic model helps in promoting the successful running and completion of a program through the role it plays in the planning, organization, management, monitoring and evaluation of the program. Through the model, organizations can be able put together all the elements that relate to a program undertaking and that include goals, objectives, tasks, available resources among other factors.
It serves as a clarification of what a program hopes to achieve, the effective way to monitor program activities, on how to evaluate the program. It helps in ensuring that programs stay on track, and are excellent ways of documenting programs (Bert & Wegner, 2009).
Logical and physical models represent business requirements and database schemes, and are both used in creating data models. Also, they both reduce the development and maintenance time and costs, facilitates avoidance of data redundancy and aid in common understanding of business data elements and requirements. American express has a long standing commitment to protect card member information by ensuring its safety.
Compromised data impact negatively and can compromise a business’s reputation and weaken its ability to successfully operate its activities. The company has tried to deal with this threat by implementing express data security operating policy to increase customers’ trust and by being a member of the Security Standards Council with an aim of improving the its reputation (Schmitz, 2004).
