Abstract: The problems existing in the field of information technology for a long time are more and more serious due to the limitation of software architecture. Information between different systems is burdensome to share, and it is difficult to expand the built-up systems. Besides, data in massiveness, heterogeneity, various sources, real-time, dynamic and in explosive growth, are unmanageable, difficult to analyzing and mining. There are several problems in business-oriented software engineering, notably, it is hard to manage the process of developing and maintaining. The software life-cycle is not usually sustained. What is more, the problem of information security and data security is facing a challenge in network-opening environment. And more, the benefits of data owner will not usually be protected. This paper brings up a new architecture called data-oriented software architecture (DOA), which is designed by the ideology of “orienting data” and “data as kernel”. The DOA systems define, manage data and provide services through data register center (DRC), data authority center (DAC) and data exception control center (DEC). In addition, the data application units (DAUs) are designed to realize the management of various kinds of applications. The destination is to set up a data ecosystem for big data platforms and fragmented applications. This paper explores the architecture which considering the mechanism of data protection and authorization in the age of big data.
