Data processing method and device and transaction data processing method and device

The invention provides a data processing method and device and a transaction data processing method and device. Due to the fact that corresponding preset rollback logs are set for a database in advance, before resource managers are called to conduct sub-processing on a responsible database according to a data processing request, the preset rollback logs are used for recording the related data of the database involved in subsequent sub-processing as the target data, After subprocessing, according to the fed back sub-processing result, a sub-processing result is acquired. When a judgment is madethat a first preset requirement is met, a sub-processing result is called to a successfully-processed resource manager. According to target data recorded by a rollback log, rollback operation is performed so that user operation is simplified. Processing efficiency is improved, and data recovery and restoration can be automatically and efficiently carried out on the database with successful sub-processing under the condit
