CORE - Contract Online Reporting
CORE is a PHP and MySQL reporting platform built for Contract Group to digitize automotive quality-control reporting, daily inspection entry, and multi-database operational reports.
- Primary stack
- PHP + MySQL
- Data model
- Multi-database
- Focus
- Quality reporting
Overview
CORE was a custom web platform for entering, tracking, analyzing, and exporting quality-control inspection data. The codebase includes admin and user panels, reporting screens, Excel exports, file handling, notifications, and mobile-facing service endpoints.
A key part of the project is its multi-database structure: company-specific databases are opened dynamically and combined in reports when operational data spans multiple companies or work areas.
Problem
- Field operators recorded inspection results on paper, then reporters transferred those notes into Excel.
- Reporters manually calculated work durations and shared the daily Excel report with customers by email.
- Operational data was distributed across company-specific databases, so reporting needed to query and combine records across separate data stores.
- Teams needed a central place for orders, inspection records, personnel, part definitions, files, and operational reports.
Solution
The platform centralizes inspection entry and reporting in a PHP/MySQL web application. The user panel focuses on order and inspection workflows; the admin panel covers authorization, personnel records, reporting, invoicing/time screens, notifications, and configuration.
With CORE and its mobile workflows, field operators could enter inspection results directly from tablets. Internal teams and customers could then review shift results through the CORE portal instead of waiting for a manually prepared daily Excel report.
The codebase also includes backend/API endpoints used by related mobile applications, so CORE was not only a web panel but part of a wider internal operations system.
Key Features
- Role-separated admin and user panels for operational and management workflows.
- Order, part, shift, operator, place, line, and control-criteria management.
- Inspection movement entry with OK, NOK, rework, traceability fields, and detailed result review.
- Monthly and daily quality reports with totals, defect ratios, PPM-style metrics, elapsed time, and detailed result tables.
- Excel export flows for quality reports, personnel lists, invoices, time reports, and activity reports.
- Notification, password reset, file management, QR/barcode, and mobile app support modules.
- Turkish and English language files for core reporting and panel screens.
Technical Notes
- Built primarily with PHP, MySQL, JavaScript, HTML, and CSS.
- Uses server-rendered PHP pages with shared layout includes, language files, AJAX-style JavaScript helpers, and report-specific export endpoints.
- Includes multi-database query patterns for company-specific operational data, with dynamic database connections and aggregated reporting across related company datasets.
- Uses common frontend libraries together with PHP mail and export utilities for reporting workflows.
Outcome
CORE helped digitize Contract Group's quality-control reporting and related operational processes. For the portfolio, it represents practical PHP/MySQL full-stack development, multi-database reporting, and long-term maintenance of an internal business platform.
