Adaptive Business Logic
Build systems that automatically recalculate and adapt decisions when underlying data changes. No manual recomputation or cache invalidation needed.
Overview
Business logic often depends on multiple data sources. When any source changes, decisions become stale. Traditional systems require manual recomputation, cache invalidation, or event choreography. Slung automatically handles dependency tracking and recomputation when facts change.
The Challenge
Complex business logic depends on many factors: user segments, pricing tiers, inventory levels, regional rules, and compliance requirements. When any factor changes, you need to recompute affected decisions. This leads to stale caches, inconsistent decisions, and brittle systems that break when new factors are added.
How Slung Helps
Define business logic as rules that depend on facts. Slung automatically tracks which facts each rule depends on. When a fact changes, all affected rules automatically re-evaluate. Your business logic is always consistent with the current state, and new rules can be added without breaking existing ones.
Key Benefits
Always Fresh Decisions
Business logic automatically recomputes when any dependency changes. No stale caches or manual invalidation.
Automatic Dependency Tracking
Slung tracks which facts each decision depends on. Only affected rules re-evaluate when changes occur.
Easy to Extend
Add new rules and facts without breaking existing logic. Dependencies are automatically resolved.
Audit Trail
See exactly which facts triggered which decisions and when. Full traceability for compliance.
Example: Pricing Engine
A pricing engine that depends on multiple factors:
• Customer segment (enterprise, SMB, startup)
• Purchase volume and history
• Regional pricing regulations
• Current inventory levels
• Competitor pricing and market conditions
• Active promotions and discounts
Define rules for each pricing factor. When inventory drops, competitor prices change, or a promotion starts, all affected price calculations automatically re-evaluate. Customers always see current, accurate prices without manual recomputation or cache busting.
