Business Architecture And Explanations


Information systems and communication systems, within an organization if not built upon a design or design that is clear at the start of its construction will undermine the harmony of the system. Efforts to avoid disturbance to the system harmony at the time of development sustem is to plan the system clearly before the system is built. Planning the system as a whole (covering all aspects of the organization) is what is known as Enterprise Architecture.

Enterprise Achitecture provides a clear and comprehensive picture of an organization’s mission, vision, functions, objectives and systems that support the implementation of organizational functions. The concept of architecture first appeared in 1980, since it began to be developed and perfected by various research and development institutions.

Definition of EA

The word Architecture is generally related to the design of a building or building. When we are going to build a house, we first create an image of the architect. Then we do the development by referring to the architectural drawings. Similar concepts can be applied to build information and communication systems within an organization.

Enterprise is a business description of an organization in a complex form, it has a very wide range of people (customers, staff and contractors), processes and assets used to develop and produce products and services, data and information stored for use in business, and mechanisms for providing communication and security.
Enterprise architecture is a logical organization for business processes and IT infrastructure related to integration and standardization requirements of a company’s Operating Model. The basic elements of enterprise architecture vary, depending on the Operating Model used. The key to achieving an effective enterprise architecture is to identify processes, data, technologies and interfaces with customers so that the Operating Model can become a reality and not just a vision.

Enterprise architecture deals with how communication is made or built from high-level business processes and from the IT needs of an enterprise Operating Model. Typically, enterprise architecture is represented in the form of principles, policies and technological choices which are then all poured into a diagrammatic image that can represent the three components (processes, data, and technology). This diagram is called the core diagram (core diagram).

Core diagram contains a description of the business units along with the transaction process and the interrelationships between units in running their business processes. This diagram works like a blueprint on an architectural drawing as the basis of a company’s business architecture. Core diagrams provide a platform for managers to build and develop enterprise architecture.

As shown in Figure 1 above there are 4 layers in EA.
In the first layer is the business layer that includes knowledge and definition of the business and includes attention to the guarantee / security.

The second layer is the data layer, in this layer defines the data that is important to support the business include object and data models, structures, definitions of data and information flow including on this layer the documentation of sensitive data / crucial and its security.

The third layer is the application layer, in this layer defines the applications that support the business includes a description of the function of the application, the definition of the application design, interfaces and the ability to be accessed including with security / guarantee.

The fourth layer is the technology layer, in this layer defines technologies that support the business include business locations, hardware and software, networking and technology security.
There are various definitions of EAP in some writings and scientific journals, this is due to the breadth and complexity of coverage to be reached. But in this paper we will limit it by referring to the definitions given by Steven H. Spewak.

EAP (enterprise architecture planning) is the process of defining the architecture architecture for the use of information in supporting the business and the plan to implement the architecture.

There are 3 important words in the definition above. First is the word architecture gives blueprint meaning, image or model which consists of 3 architecture that is data architecture, application architecture and technology architecture. In particular, the EAP architecture defines and describes the data, applications and technologies necessary to support the business.

The second is the defining word. EAP defines business and defines architecture. EAP is a defining process rather than a design, so EAP does not design systems, databases or networks. Design and implementation work is initiated after the EAP definition process has been completed.

Third is the word plan. Generally the architecture defines what (what) is needed and the support plan defines when the architecture is implemented. In fact, the architecture itself can provide definitions, standards and useful ideas, but unplanned plans will not reach until the implementation stage. (DCW)
