摘要

Disclosed are a system and a method for efficiently processing and analyzing big data by using a columnar index data format. A method for processing big data in a processing system implemented with a computer comprises the steps of: generating a dictionary by arranging pieces of data in a column unit of the big data; classifying the arranged pieces of data as one or more data blocks every dictionary according to sizes of the pieces of data; generating an index including values of pieces of first data of the data blocks according to an order of the data blocks every dictionary; and generating a column identification for each column in a row order of the big data.
