Using incremental calculation methods on materialized views maintenance can be beneficial for quick access to views, query optimization and so on in the digital library.This paper presents a new method of view incremental calculation named PCA.And this method can efficiently compensate for the error caused by deferred calculation using partial compensation.It compensates only once for the data of every base table.It's time complexity is only O(n 2 ) verified by the experiment.
