When the computer program is executed by one or more processors of a source database server, the computer program performs steps for Change Data Capture (CDC) by one or more processors. The steps may include: identifying a plurality of Structured Query Language (SQL) operations generated for one or more objects associated with a transaction by analyzing a log record including information about the transaction processed at a source database server; determining whether a previous SQL operation history for an object corresponding to an individual SQL operation is in a CDC file, based on whether an order in which the plurality of identified SQL operations occur; determining information to write on the CDC file based on whether a previous SQL operation history is in the CDC file; writing the determined information on the CDC file; and deciding to send the CDC file to a target database server.
