database-as-a-Service (DAS) is an emerging database management paradigm wherein partition based index is an effective way to querying encrypted data. However, previous research either focuses on one-dimensional partition or ignores multidimensional data distribution characteristic, especially sparsity and locality. In this paper, we propose Cluster based Onion Partition (COP), which is designed to decrease both false positive and dead space at the same time. Basically, COP is composed of two steps. First, it partition covered space level by level, which is like peeling of onion;second, at each level, a clustering algorithm based on local density is proposed to achieve local optimal secure partition. Extensive experiments on real dataset and synthetic dataset show that COP is a secure multidimensional partition with much less efficiency loss than previous top down or bottom up counterparts.

Based on the analysis of problems and difficulties in apparel quotation system, this paper puts forward the combination of BPM and SOA as a new idea for analysis of apparel quotation system, according to their advantages in business goals and requirements analysis, and the corresponding services' definition, extraction, optimization and integration. Through the combination, system flexibility, rapidity and accuracy could be achieved. The establishment of Service Repository according to the business requirements, is a crucial part in the architecture, however there are no definite rules for service extraction. In this paper, the detailed activities and steps, as well as a specific establishment case is illustrated. At last, architecture based on BPM and SOA for the apparel trade quotation is put forward, and its composition and implement are also analyzed.
