METHOD FOR PRE-LOADING IN MEMORY AND METHOD FOR PARALLEL PROCESSING FOR HIGH-VOLUME BATCH PROCESSING

摘要

The present invention relates to a high-volume information batch-processing method which is based on a relational database. The high-volume information batch processing method according to the present invention pre-loads second comparative data from a second database into a memory by checking and processing same, withdraws first comparative data for a specific identifier from a first database by checking and processing same, retrieves second comparative data for the specific identifier from the memory, outputs a cross-checking result by cross-checking the second comparative data and the first comparative data for the specific identifier, and thus secures the memory by deleting from the memory the second comparative data and first comparative data for the specific identifier, which have undergone cross-checking.
