Query-Specific Event Handlers for Database Update Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interfaces often present outdated data due to frequent changes in voluminous databases, necessitating continuous updates, which can be impractical and inefficient.
Innovation Solution
Implementing query-specific event handlers to monitor and update only affected query results, reducing unnecessary reevaluation and bandwidth usage by registering event handlers at a server to detect changes and notify the user interface to resend specific queries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous updates are implemented to keep user interface data current, then data freshness is improved, but system resource consumption and bandwidth usage increase significantly
Solution Approach 1:
The patent segments the update mechanism by implementing query-specific event handlers that monitor only the particular objects and aspects relevant to each query. This allows the system to update only the specific query results that have changed, rather than continuously updating all data, thereby reducing bandwidth consumption while maintaining data freshness for relevant information.
Solution Approach 2:
The system implements event-driven periodic updates where query results are refreshed only when specific change events occur. Event handlers are registered to detect changes to monitored objects and aspects, triggering query reevaluation only when necessary. This eliminates continuous polling and reduces bandwidth usage while ensuring data remains current when changes actually occur.
2Loss of information
If query results are continuously reevaluated to ensure data currentness, then data freshness is improved, but processing time and system productivity deteriorate
Solution Approach 1:
The patent applies preliminary action by pre-registering event handlers for specific objects and aspects that are relevant to query results. These handlers are set up in advance to monitor for changes, so when a change occurs, the system can immediately reevaluate only the affected queries rather than continuously reevaluating all queries. This maintains data currentness while improving system efficiency by avoiding unnecessary processing.
Solution Approach 2:
The system segments the query evaluation process by identifying and monitoring only the specific objects and aspects that affect each query result. When changes occur, only the relevant subset of queries is reevaluated rather than the entire query set. This selective approach maintains data currentness for affected queries while significantly reducing overall processing time and system resource consumption.
3Loss of information
If all query results are updated whenever database changes occur, then data completeness is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent segments the update mechanism into query-specific event handlers that are tailored to monitor only the objects and aspects relevant to each query. This targeted approach ensures that when database changes occur, only the specific query results that are affected are updated and sent to the user interface. This maintains data completeness for relevant queries while reducing the complexity of the update mechanism by avoiding unnecessary updates to unrelated data.

AI summary
In one aspect, a computer-implemented method may provide evaluation of a query based on query-specific event handlers. The method may include receiving a query. Moreover, one or more objects and aspects of the objects may be determined based on the received query. The objects and aspects may be registered with event handlers to monitor the objects and aspects. The received query may be evaluated, when at least one of the event handlers indicates a change to at least one of the objects and the aspects. Other event handlers may be registered, when at least one of the event handlers indicates the change. Related systems, apparatus, methods, and/or articles are also described.
