In this paper, some interesting issues related to vertical partitioning in object oriented database systems are presented. A review of existing research is given with an identification of some open problems. A taxonomy of various possible partitioning schemes and a unified view of the vertical partitioning problem are also presented. Existing vertical partitioning algorithms have been studied f...

Abstract On the basis of traditional ABC classification method, this paper determines another standard to subdivide goods, that is, hierarchical method. The calculation shows that, based on efficiency multi-layer horizontal rotating shelves is increased by 26.94% and vertical 37.25%. partition design scheme helpful optimize operation shelf warehousing system verifies validity rationality design.

Network traffic classification (NTC) plays an important role in cyber security and network performance, for example intrusion detection facilitating a higher quality of service. However, due to the unbalanced nature datasets, NTC can be extremely challenging poor management degrade performance. While existing methods seek re-balance data distribution through resampling strategies, such approach...
