Large amount of uncertain data is inherent in many novel and important applications such as sensor data analysis and mobile data management. A probabilistic threshold range aggrega...
Abstract. We developed the Nested Relational Sequence Database System (NRSD System), which is built upon the Nested Relational Sequence Model (NRSM). The NRSM eliminates a substant...
Data exchange is the problem of taking data structured under a source schema and creating an instance of a target schema. Given a source instance, there may be many solutions ? ta...
Emerging applications using miniature electronic devices (e.g., tracking mobile objects using sensors) generate very large amounts of highly dynamic data that poses very high overh...
This paper presents a structure we call XML Wavelet Tree (XWT) to represent any XML document in a compressed and self-indexed form. Therefore, any query or procedure that could be ...
