Database Record Position Numbering via Digit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database management systems face inefficiencies when inserting or deleting data records, requiring frequent recalculations of position numbers, leading to high computing capacity usage and complex transactions, especially when updating sequences of data records.
Innovation Solution
A method for storing data records in a database that compares and sorts position numbers by processing digits from left to right, allowing for efficient insertion and management of data records without recalculating position numbers, thereby reducing computation time and electricity consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional sequential numbering is used for data records, then the sequence can be easily understood and maintained, but inserting or deleting records requires recalculating position numbers for many records, leading to high computing capacity usage and time consumption
Solution Approach 1:
The position number is segmented into multiple digit positions (e.g., thousands digit, hundreds digit, tens digit, units digit), where each digit represents a specific level of the sequence hierarchy. This segmentation allows insertion operations to only affect digits at or below the insertion point, rather than requiring recalculation of all position numbers in the sequence.
Solution Approach 2:
The system pre-allocates position numbers with sufficient digit positions to accommodate future insertions without requiring recalculation. By designing position numbers with fixed digit structures (e.g., 4-digit positions), the system prepares for potential insertions in advance, eliminating the need for costly recalculations when insertions occur.
2Reliability
If position numbers are recalculated for all records during insertion or deletion, then the sequence remains accurate and unique, but the complexity and time consumption of data-access transactions increase significantly
Solution Approach 1:
The position numbering system dynamically adapts to insertions and deletions by only modifying digits at or below the affected position, rather than statically recalculating all position numbers. This dynamic approach maintains sequence accuracy while significantly reducing the complexity of data-access transactions.
Solution Approach 2:
Instead of applying global recalculation to all position numbers, the system applies local modifications only to the specific digit positions affected by an insertion or deletion operation. This localized approach preserves sequence integrity while minimizing the scope and complexity of required transactions.
3Stability of the object's composition
If all existing data records are updated when inserting a new record at the first position, then the sequence remains consistent, but the computing capacity and time required increase considerably
Solution Approach 1:
By segmenting the position number into hierarchical digit positions, the system identifies that insertions at higher levels (e.g., thousands digit) only require updating position numbers from that level downward, rather than updating all records in the entire sequence. This segmentation dramatically reduces the number of records that need updating.
Solution Approach 2:
The system pre-structures position numbers with fixed digit positions that can accommodate insertions without requiring widespread updates. This preliminary structuring ensures sequence consistency is maintained while minimizing the computational energy required for insertion operations.
Data Source
AI summary
A method for storing a sequence of data records in a database comprises the following steps: creation of a database for storing data records in a creation step, insertion of at least two data records in the database in an insertion step, execution of at least one sorting step, with the data records each comprising an integer position number with at least one digit. In each sorting step, the position numbers of two data records are compared in order to specify and/or determine the sequence of the two data records. Comparison is then performed by processing the digits of the two position numbers individually from left to right and comparing them. One position number is greater than the corresponding other position number as soon as one of its digits is greater than the corresponding digit of the other position number, or if all its digits are identical to the corresponding digits of the second position number and the second position number still has further digits.
