摘要： Methods and apparatus, including computer program products, are provided for data replication. In one aspect, there is provided a computer-implemented method. The method may include providing an initial load of a data item from a source system to a target system, wherein the data item is associated with a trigger maintained at the source system; recording a change in a log, when a change to the data item at the source system causes the trigger to prompt the recording; extracting the change from the log to enable at least a confirmation of a consistency of the change; and providing the extracted change to a replication server configured to write the change to the target system. Related apparatus, systems, methods, and articles are also described.

摘要： The present invention provides systems and methods for migrating data from at least one data source to at least one data target according to one or more migration objects or migration rules. The migration rules, for example, may control how the data migration is done. For instance, the migration rules may describe how the source data may be modified during the migration process to meet the requirements of the target system. In exemplary embodiments, a neutral interface is provided which comprises a mapping of external data fields to business objects located on the target system.

摘要： In one general aspect, a computer system can include instructions stored on a non-transitory computer-readable storage medium. The computer system can include a logging table generator configured to generate a logging table corresponding with an original table targeted for an upgrade, and a control table generator configured to generate a control table configured to store a version identifier for changes logged in the logging table. The computer system can include a change recorder configured to receive an indicator of a change to a record of the original table during execution of at least a portion of the upgrade of the original table, and a key recorder configured to store in the logging table a primary key identifying the record of the original table and the version identifier stored in the control table.
