Data security helps maintain privacy of data. There are a number of data security technologies to support this process. They are as follows:
The topic of my research paper is Enterprise Information Architecture that strategically brings together the information architecture of the organization in a well-documented and logical manner. EAI integrates the information architecture of within an organization in such a way that the organization wide elements of goals, objectives, strategic plans etc also encompass within the architecture.1
EAI aims to provide an architectured environment to the organization that delivers high quality, system integration, time saving and reduction in costs. This aim is achieved by EAI by eradicating or reducing data redundancy within the operational systems, eradicating or reducing process redundancy within the operational systems, and by minimizing the complexity of extracting data from the operational environment into the data warehouse environment. The EAI is often known as a vehicle that provides a road map to development of an architectured environment. The EIA has three sub-architectures and they are as follows:
Business architecture: This includes corporate data model (business oriented and integrated view of the data that is important to the organization), function model (decomposes the core business functions performed within the organization), interaction model (a matrix that shows which data is updated, deleted or important), current systems model (inventory of current systems implemented within the organization).
Technical architecture: This depicts the existing and desired technical environment of the organization. It also includes an inventory of the systems of the existing technical environment as well.
Organization architecture: This reveals the processes from the function model that are performed by each unit within the organization. It also shows the organizational structure but at a higher level.
Below is the breakdown of the EIA:
Enterprise information architecture is a model that has four levels and they are as follows:
Physical level: This level encompasses the computer hardware of the organization, network interface, telecommunication facilities and the LANs that support the intranet and extranet. Previously systems in organizations used to be monolithic and centralized but now they are more decentralized and distributed in the form of client/server, network-based computer systems etc.
Information level: This level is concerned with the information of the organization like databases, model bases, knowledge bases and metabases. This
