Abstract :
Extensive effort has been brought forth to assist in data management. In particular, classic information integration systems and database systems techniques are exploited to manage evolving data. However, these works require hard up-front investment before offering powerful functionalities. To address the question, data space, a new style of data management, was proposed in 2005 SIGMOD. In this paper, a general framework based on data space techniques is presented to manage data in a pay-as-you-go fashion, and the core components of the framework are specifically explained. Moreover, the differences between pay-as-you-go fashion and pay-before-you-go fashion in data management are discussed.
