Abstract

The present invention contemplates a non-transitory computer readable medium including a computer program steps for a change data capture (CDC) between a first database and a second database when executed by one or more processors of the computer system. The disclosed non-transitory computer readable medium contemplates receiving data from a first database by a second transceiver module, the data including a null data contained in an encrypted column and a data contained in a non-encrypted column of a table, generating, by the second management module, a change data, by reproducing transactions performed in the first database with respect to the data transmitted from the first database and performing a processing on a transaction before commit, and determining, by the second management module, to request an encrypted column data corresponding to the null data to the first database.
