Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
Complex classes like reports.combinedequipmentstatistics often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

| 2 | Combined Equipment Statistics Report API |
||
| 3 | |||
| 4 | This module provides REST API endpoints for generating combined equipment statistics reports. |
||
| 5 | It analyzes statistical data and performance metrics for combined equipment to provide |
||
| 6 | comprehensive insights into combined equipment performance and operational patterns. |
||
| 7 | |||
| 8 | Key Features: |
||
| 9 | - Combined equipment statistical analysis |
||
| 10 | - Performance metrics calculation |
||
| 11 | - Statistical trend analysis |
||
| 12 | - Performance benchmarking |
||
| 13 | - Excel export functionality |
||
| 14 | - Statistical insights and patterns |
||
| 15 | |||
| 16 | Report Components: |
||
| 17 | - Combined equipment statistics summary |
||
| 18 | - Performance metrics and KPIs |
||
| 19 | - Statistical trend analysis |
||
| 20 | - Benchmarking data |
||
| 21 | - Performance indicators |
||
| 22 | - Statistical patterns and insights |
||
| 23 | |||
| 24 | The module uses Falcon framework for REST API and includes: |
||
| 25 | - Database queries for statistical data |
||
| 26 | - Statistical calculation algorithms |
||
| 27 | - Performance analysis tools |
||
| 28 | - Excel export via excelexporters |
||
| 29 | - Multi-language support |
||
| 30 | - User authentication and authorization |
