Johannesburg - Enumerations vs Master Data in Mendix: Speed vs. Flexibility

Details
Choosing between enumerations (enums) and master data (reference entities) for dropdowns and selectors in Mendix directly affects maintainability, flexibility, and performance of your application. In this session, we’ll guide developers, architects, and project leads through the trade-offs of using enums versus master data, helping you make data-model decisions that align with both short-term deadlines and long-term scalability.

We’ll explore:

• The conceptual difference: enums as design-time, code-defined lists versus master data as runtime-editable entities
• How each approach impacts deployments
• Performance considerations when loading static enums versus querying reference entities
• Real-world scenarios: when a small, unchanging list makes enums ideal, and when business-driven lists call for master data
• Best practices for modifying, and extending dropdown values without excessive maintenance overhead
• A live demo showing the benefits of both
