The information-driven society we live in forces enterprises everywhere to manage their digital data effectively and maintain business competencies. Databases allow enterprises to effectively manage and control accessibility of the information available.

The Rise of Databases

In the last decade, we have been witness to an exponential increase in all kinds of digital data starting from user-generated review to banking records. Some of these digital documents are openly available for discussions in public forums, while access to other digital documents is restricted by law. In the post Web 2.0 world where enterprises are moving towards paper-free environments, maintaining and securing such digital documents has gained paramount importance among corporations world-wide. Databases were thus developed to ensure enterprise-wide information/digital document availability throughout the enterprise, while simultaneously ensuring compliance with all relevant local and international laws.

What are the Database Architecture Choices available to an Enterprise?

Enterprises currently deploying databases can opt from any one of three distinct database architecture ? single tier, two tier and multi tier database architectures. Each of these architecture types is suitable for a particular type of organization. Several factors influence the final choice of database architecture, for an enterprise. Some of the key factors affecting the choice of architecture are discussed next.

Data Processing Requirements

This is a leading factor influencing choice of database architecture for an enterprise. In case of higher data volumes, enterprises would prefer to deploy the n-tier approach, whereas, for smaller data processing requirements, a single tier or two-tier approach might be more suitable or feasible.

Business Policies

Various business policies such as regulatory requirements, compliance necessities and internal organizational policies also affect the choice of deployed architecture. Such policies can potentially limit the number of users accessing an enterprise database and influence the choice of database solutions for use by the organization.

Macro Economic Factors

Macro economic factors affecting an enterprise such as business cycle, legal considerations, market conditions and interest rates also exert considerable influence on the decision to choose specific database model. Such macro economic factors in principle alter the cash flow within an organization and lead to policy changes which affect database deployment plans. About Author
