Building a Common Enterprise Technical Architecture for an Universal Bank

Researches on enterprise architecture mainly focus on business process organizing, software development, enterprise application integration and etc., but not much emphasis is focused on the enterprise technical architecture and its components. The paper proposed a domain based integrated enterprise technical architecture for a universal bank, helping to build common patterns to manage bank's technical IT applications and infrastructure in a unified IT environment. The authors also propose to define the enterprise technical architecture in different levels based on the bank's real business need referring to the enterprise business architecture and industry's best practices like TOGAF 9 and Zachman Framework. It is concluded that the proposed enterprise technical architecture with its holistic view of all the technical component patterns will enhance the effectiveness of the bank IT lifecycle management and also increase the adaptability with a controlled manner.
