PROBLEM TO BE SOLVED: To provide a data processing method for a data processing system allowing reference to data in a state that consistency between a plurality of pieces of takeout source data is secured. SOLUTION: The data processing system includes: a consistency condition 125 indicating a condition wherein the consistency is secured to an application; a consistency target 126 indicating the data allowing the reference from the application; and a consistency definition 124 including a group key 127 necessary to decide the data allowing the reference when satisfying the consistency condition. All pieces of update information obtained from an optional database in real time are temporarily stored in a buffer, it is decided whether or not the update information satisfies the consistency condition when it is necessary for the obtained update information to secure the consistency to the application referring to the update information, and all the pieces of the update information narrowed down by the group key and the consistency target from the update information stored in the buffer till a time point when satisfying the consistency condition is brought into a state allowing the reference at the time point.
