Question 480
An inventory extension performs repetitive database calls to create a simple grouped stock summary. A targeted trial still reproduces the original gap after the team attempted this change: Evaluate replacing the record loop with a database-backed query and aggregation. Which repair directly addresses the remaining defect?
Explanation
Correct Answer
Refactor the record traversal to a query with correct aggregation and benchmark the filtered result. This directly addresses the remaining defect for the requirement—An inventory extension performs repetitive database calls to create a simple grouped stock summary. It restores the mechanism described here: queries can move joins and grouping nearer the data source and reduce redundant al record iterations.
Incorrect Answers
This correction is for the separate condition: A partner exposes an aggregated API query and expects PATCH and POST operations to update source records. It would not directly restore the intended behavior in this situation: An inventory extension performs repetitive database calls to create a simple grouped stock summary. Here, refactor the record traversal to a query with correct aggregation and benchmark the filtered result, because queries can move joins and grouping nearer the data source and reduce redundant al record iterations.
This correction is for the separate condition: A purchasing dashboard needs vendor details joined with the relevant purchase lines for quick analysis. It would not directly restore the intended behavior in this situation: An inventory extension performs repetitive database calls to create a simple grouped stock summary. Here, refactor the record traversal to a query with correct aggregation and benchmark the filtered result, because queries can move joins and grouping nearer the data source and reduce redundant al record iterations.
This correction is for the separate condition: An analyst needs grouped revenue totals by region from existing posted transactions. It would not directly restore the intended behavior in this situation: An inventory extension performs repetitive database calls to create a simple grouped stock summary. Here, refactor the record traversal to a query with correct aggregation and benchmark the filtered result, because queries can move joins and grouping nearer the data source and reduce redundant al record iterations.
