Identifying Database Bugs A bug was discovered in the database related to employee training courses. Initially, everything appeared fine with a small dataset, but issues arose when more data was added. The problem involved missing HR course requirements for certain employees due to incorrect query relationships.
Deconstructing Query Relationships The investigation began by examining the list box's row source and simplifying its structure for clarity. Queries were checked sequentially to trace where data retrieval failed, revealing that some queries returned no results because of improper joins between tables.
Correcting Join Conditions Upon reviewing the employee course requirements table linked with actual enrollment records, it became clear that additional join conditions were necessary. A second outer join based on both Course ID and Employee ID corrected this oversight and allowed all required courses to display properly.
Creating Reports on Missing Training 'Employee Missing Courses' report creation commenced using existing queries showing which employees lacked specific trainings or had expired certifications. Groupings by Employee ID facilitated organized reporting of missing classes per individual within an easily readable format.
.Design Enhancements for Clarity. 'Missing Training Report' design included grouping levels sorted first by Employee ID then last name while ensuring relevant fields displayed correctly without unnecessary headers or footers cluttering layout aesthetics during preview mode adjustments
'Main Menu Integration' aimed at providing quick access through a button linking directly into 'Missing Training Report.' This feature enhances user experience allowing immediate visibility into training deficiencies across staff members efficiently from one central location
