Thirdly, this thesis discusses the issues during large number of concurrent TCP connections. The concurrencymode described in the second part is improved to a new solution: balanced load thread pool.
DELUXE mode provides more concurrency to the target table while loading, whereas EXPRESS mode expects the target table to be a RAW table.
DELUXE在加载时向目标表提供更多并发性，而EXPRESS模式期望目标表是一个raw表。

This paper presents a model for object -oriented distributed transactions, and proposes the concurrency control algorithm that fits this mode. In this paper, the algorithm has been proved.
