Mapping Rules
Sector Assignment Rules
- Single Sector Only: Each organization belongs to exactly one primary sector
- Primary Purpose: Assign based on the organization's main business purpose
- Revenue Source: Consider primary revenue-generating activity
- Target Audience: Factor in whether serving consumers, businesses, or government
Business Type Assignment Rules
- Multiple Types Allowed: Organizations can have multiple business types
- Specific Characteristics: Choose types that best describe specific aspects
- Operational Model: Consider how the business operates (local, chain, online, etc.)
- Service vs Product Focus: Distinguish between service and product-oriented businesses
Service Category Assignment Rules
- Functional Purpose: Based on what need the organization fulfills
- User-Centric: Focused on how users would search for or need these services
- Multiple Categories: Organizations can serve multiple functional purposes
- Cross-Sector: Categories span across different sectors
Filtering Strategy
Primary Filtering Dimensions
By Sector (Industry-based filtering):
- Find all healthcare organizations
- Show manufacturing companies
- Locate educational institutions
By Business Type (Operational filtering):
- Find all local businesses in an area
- Show chain restaurants
- Locate professional service providers
By Service Category (Need-based filtering):
- Find emergency services
- Show daily living essentials
- Locate entertainment options
Advanced Filtering Combinations
Multi-dimensional filters:
- Healthcare services that are local businesses
- Professional services in education sector
- Retail businesses providing essential daily services
Geographic + Categorical:
- Essential services within 2km
- Professional services in specific neighborhoods
- Educational institutions by sector and type
Implementation Guidelines
Data Structure
interface OrganizationCategory {
primarySector: PrimarySector;
businessTypes: BusinessType[];
serviceCategories: ServiceCategory[];
}
Database Schema Considerations
- Primary sector as required field
- Business types as array/tags
- Service categories as array/tags
- Validation rules to ensure logical consistency
UI/UX Considerations
- Primary filtering by service categories (user needs)
- Secondary filtering by sectors (industry expertise)
- Tertiary filtering by business types (specific preferences)
- Progressive disclosure of filter options
Migration Strategy
From Current System
- Map existing sectors to new primary sectors
- Translate subtypes to appropriate business types
- Add service categories based on functional purpose
- Validate mappings through testing and user feedback
Data Quality Improvements
- Consistency checks: Ensure logical sector-business type relationships
- Completeness validation: Require all three categorization levels
- User testing: Validate that filtering meets user needs
- Iterative refinement: Adjust categories based on real usage patterns
Benefits of New System
For Users
- Intuitive filtering: Find services based on needs, not technical categories
- Comprehensive results: Multi-dimensional search captures all relevant organizations
- Progressive refinement: Start broad, narrow down based on preferences
For Administrators
- Scalable structure: Easy to add new categories without breaking existing ones
- Data quality: Clear rules prevent inconsistent categorization
- Analytics ready: Structured data enables better insights and reporting
For Developers
- Clean architecture: Separation of concerns between sectors, types, and categories
- Flexible querying: Support for complex filter combinations
- Maintainable code: Clear categorization logic and validation rules
Future Extensions
Additional Dimensions
- Size categories: Small local businesses vs. large enterprises
- Accessibility features: Services accommodating specific needs
- Sustainability ratings: Environmentally conscious businesses
- Quality certifications: Accredited and certified organizations
Integration Points
- User preferences: Personalized filtering based on user profiles
- Time-based services: Hours of operation and availability filtering
- Rating and review integration: Quality-based filtering options
Appendix: Current System Analysis
Issues with Current System
- Sector/Subtype confusion: 54.6% of organizations have identical sector and subtype values
- Limited filtering dimensions: Only two levels of categorization
- User-centric gaps: Categories not aligned with how users search for services
- Scalability concerns: Adding new categories breaks existing logic
