METHOD FOR STORAGING IN MEMORY AND PARARELL-PROCESSING FOR BATCH PROCESS OF MASS INFORMATION

摘要

PURPOSE: A memory load and parallel processing method for massive batch processing is provided to implement a massive database based on a relational database and to select and process massive data, thereby reducing the number of database calls. CONSTITUTION: Second comparison information is inquired and processed from a second database and is loaded to a memory(S101). First comparison information of a specific identifier is inquired, processed, and drawn from a first database(S102). The second comparison information of the specific identifier is searched from the memory(S103). A cross-check result is outputted by performing cross-check for the first comparison information and the second comparison information of the specific identifier(S105). The first comparison information and the second comparison information are deleted in the memory(S106).
