  • Method, computer readable storage medium and computer system for obtaining snapshots of data
    Patent number: 9201738
    Abstract: A method includes requesting a source database system including a source database table to record a transaction log including a plurality of transaction log entries that are representative of transactions including modifications of the source database table and to create a snapshot of the source database table during the recording of the transaction log. For each of a plurality of snapshot entries in the snapshot, one or more validity time intervals during which the snapshot entry is valid are determined on the basis of the transaction log. The snapshot entry is valid as long as it matches a corresponding entry in the source database table. A point in time at which a number of valid ones among the plurality of snapshot entries is maximum is determined. The calculated point in time is returned as an approximate value of a point in time at which the snapshot was created.
