Thin Import Data Migration Excluding Null Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data migration methods transfer empty address locations, represented by NULL or zero values, along with meaningful data, leading to unnecessary storage space usage in the receiving data storage system.
Innovation Solution
A method and software program that exclude data address locations containing NULL or zero values from being copied to the receiving data storage system during data migration, thereby implementing a 'thin import' approach that only transfers non-empty data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data address locations are copied during migration including empty ones, then complete data transfer is achieved, but storage space is wasted in the receiving system
Solution Approach 1:
The patent extracts and identifies empty data address locations (containing NULL or zero values) during the data migration process, separating them from meaningful data. By detecting these empty locations and excluding them from the copy operation, the system transfers only non-empty data to the receiving system, thereby conserving storage space while maintaining data integrity.
2Ease of manufacture
If empty address locations are transferred, then data migration is simplified, but valuable storage space is consumed
Solution Approach 1:
The patent performs preliminary detection of empty data address locations before the actual data copying begins. By pre-identifying which address locations contain NULL or zero values, the system can exclude them from the migration process, thereby avoiding unnecessary storage space consumption in the receiving system while maintaining a streamlined migration approach.
3Reliability
If all data locations are copied, then no data is lost, but migration efficiency decreases
Solution Approach 1:
The patent extracts empty data address locations (containing NULL or zero values) from the source system during migration, identifying them through detection mechanisms. By excluding these empty locations from the copy operation, the system reduces the total data volume transferred, thereby improving migration efficiency and productivity while maintaining data integrity for all meaningful data.
Solution Approach 2:
The patent applies partial action by copying only the necessary portion of data - specifically, only non-empty data address locations - rather than copying all data locations. This selective copying approach improves migration efficiency by reducing transfer volume while ensuring complete data integrity for all meaningful data through proper detection and exclusion of empty locations.

AI summary
The present disclosure relates to systems and methods for migrating data from one data storage system to another data storage system. A method can include copying data from one data storage system to another data storage system wherein data stored in data address locations of the first data storage system containing a NULL or zero is excluded from being written to the second data storage system.
