The present invention relates to a method and a system for encoding or decoding the data of a high-capacity table in a database and re-storing the data at high speed. The method comprises the steps of: selecting a table to be encoded in the database; determining a number of multithreads; backing up the selected table; encoding a backup target column and storing the encoded backup target column in an original table; generating threads depending on multithread number determined in the multithread number determination step; specifying an encoding range for each thread of the multithread; reading, through each thread, data in the encoding range given to each thread and encoding the read data; and storing the encoded data in the original table.
