COMPUTER IMPLEMENTED METHOD AND PROCESSING DEVICE FOR PROCESSING MAINTENANCE INFORMATION IN A DISTRIBUTED DATABASE SYSTEM USING A STORAGE CLIENT UNIT

摘要

The invention relates to a computer implemented method (10) and a processing device (100) for processing maintenance information in a distributed database system (20). In a first step S1 a task (51) from an agent (50) is received by a storage client unit (110), wherein the received task (51) comprises a maintenance operation type and a maintenance operation type dependent maintenance information. The client unit (110) comprises a storage application programming interface STO-API, linking a first database (30) of said distributed database system 20 to the storage client unit (110) and a standard application programming interface STA-API, linking a second distributed database (40) of said distributed database system (20) to the storage client unit (110). In a further step S2 a maintenance operation according to the operation type dependent maintenance information is at least performed in the first database (30) or in at least the first database and the second distributed database (40) of said distributed database system (20) on the basis of the maintenance operation type. In a further step S3 a reference is returned by the storage client unit (110) to the agent (50) depending on the performed maintenance operation. The returned reference is a reference to the maintenance in- formation within the first database (30) of said distributed database system (20). Due to the present invention, blockchain solutions can be used for scenarios where data deleting and altering functionality is required.
