Abstract
Disclosed is a computer program stored in a computer-readable storage including encoded commands. 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
