Accumulator Tables for Automated Report Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating reports in a database management system involving multiple tables is computationally expensive due to the need for join operations, which can result in incomplete reports when run at fixed schedules, missing data from events occurring outside the scheduled time.
Innovation Solution
Creating and populating accumulator tables with data fields across multiple database tables, allowing reports to be generated automatically using the accumulator table without performing join operations, ensuring completeness by linking report generation to business events rather than fixed times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If join operations are performed to combine data from multiple database tables for report generation, then the report includes complete data from all tables, but the computational cost and processing time increase significantly
Solution Approach 1:
The patent pre-joins data from multiple database tables into a single accumulator table before report generation. This preliminary action stores pre-combined data from transaction tables, inventory tables, and other source tables in the accumulator table, so that report generation only requires querying this single pre-integrated table rather than performing join operations at report time.
Solution Approach 2:
The accumulator table serves as an intermediary structure between the source database tables and the report generation process. It mediates the data integration by containing pre-joined data from multiple tables, allowing reports to be generated without direct join operations between source tables.
2Extent of automation
If reports are generated at fixed scheduled times, then the report generation process is automated and consistent, but the reports may be incomplete when business operations continue outside the scheduled time
Solution Approach 1:
The patent makes the report generation process dynamic by triggering reports based on business events rather than fixed schedules. The system monitors for events such as store closures, shift changes, or inventory milestones and automatically generates reports when these events occur, ensuring reports are always complete relative to the business context.
Solution Approach 2:
The system implements feedback mechanisms where the occurrence of business events triggers report generation. The point of sale system communicates business events to the reporting system, which then determines whether a report should be generated based on the event type and current accumulator table data, ensuring reports are generated at appropriate moments.
Data Source
AI summary
Embodiments provide techniques for creating and managing accumulator tables for use in generating reports for a business entity. Embodiments include identifying a report for a business entity. A plurality of data fields are determined across two or more database tables that are used to generate the report. Embodiments include creating an accumulator table and populating the accumulator table with data values for all of the plurality of data fields. Upon receiving, from a point of sale system, an indicator of an occurrence of a business event for the business entity, an instance of the report is automatically generated using the populated accumulator table.
