DATA MANAGEMENT PROGRAM, NODE, AND DISTRIBUTED DATABASE SYSTEM

PROBLEM TO BE SOLVED: To allow consistent data to be referred to when update of cache data is performed asynchronously by multi-site update.SOLUTION: Cache data to be at least a part of data stored to another node, a first list of transaction being executed in a distributed database system, and a first time of day showing a time of day when a request of the first list of transaction is received by a transaction management device are stored. When a reference request of a record included in the cache data is received, a second list of transaction request and a second time of day showing a time of day when the request is received are received and stored to the cache, the first time of day is compared with the second time of day, any list of transaction is selected as a third list of transaction on the basis of a result of comparison, and the third list of transaction is used to identify a generation of record to refer to.
