Database Access Types
Each database entry includes an Access Type field indicating how the database can be accessed. Understanding access types helps in planning projects, budgeting, and identifying appropriate data sources.
Access Type Classifications
Open Source
Source code/data freely available, can be modified and redistributed. Examples include GeoNames, OBIS, GBIF, and open-source translation tools.
Estimated: ~5% of databases
Free
Free to access and use (may require registration). Most government databases, UN databases, research databases, and NGO databases fall into this category.
Estimated: ~60% of databases
Free with Registration
Free access after creating an account. Many research databases, some government portals, and trade analysis tools require registration.
Estimated: ~10% of databases
Free (Limited)
Free tier with usage limits, paid options available. Common for APIs and commercial services (Google Maps API, translation services, geocoding APIs).
Estimated: ~15% of databases
Paid/Subscription
Commercial service requiring payment or subscription. Includes commercial trade databases (ImportGenius, Panjiva, Tendata), premium API services, and enterprise data platforms.
Estimated: ~10% of databases
Restricted/Institutional
Access limited to specific institutions or authorization required. Includes sensitive government data, specialized research databases, and security-related databases (INTERPOL, some CRA data).
Estimated: ~3% of databases
Mixed (Free/Paid tiers)
Both free and paid access options available. Many APIs and services offer free tiers with limited features and paid tiers with advanced capabilities.
Examples: Google Maps API, Microsoft Translator, LocationIQ
Government/Public
Publicly funded, generally free access. Most government databases, statistical offices, and public research institutions provide free access to their data.
Access Type Statistics
Based on documented databases (310+ sources):
- Free Access: ~60% (government, research, NGO sources)
- Free with Registration: ~10%
- Free Tier + Paid: ~15% (APIs, commercial services with free tiers)
- Paid/Subscription Only: ~10% (commercial trade, premium services)
- Restricted/Institutional: ~3% (specialized, sensitive data)
- Open Source: ~5% (research, open data initiatives)
- Unknown/Not Documented: ~2%
Access Planning Recommendations
For Free Access Projects
Focus on:
- Government databases (Statistics Canada, UN databases)
- Research/academic databases (GBIF, OBIS, university repositories)
- Open-source initiatives
- NGO databases (environmental, health, gender organizations)
Best Categories: Ecosystem/environmental (government), Indigenous (public resources), Gender (UN/NGO), Health (UN/government)
For Budget-Conscious Projects
Strategies:
- Utilize free tiers of commercial APIs (geocoding, translation)
- Leverage government open data portals
- Consider open-source alternatives where available
- Use free research databases (GBIF, OBIS, academic repositories)
For Commercial/Enterprise Projects
Budget for:
- Commercial trade databases (ImportGenius, Panjiva, Tendata)
- Premium geocoding APIs
- Advanced translation services
- Subscription services for real-time data, bulk downloads, advanced features
Evaluate: ROI of paid services vs. free alternatives
For Research/Academic Projects
Prioritize:
- Free research databases, open-source tools, government data
- Institutional subscriptions may provide access to paid databases
- Academic partnerships for restricted databases
Access Patterns by Database Type

- Some restricted data requires authorization
Commercial Databases
- Typically require subscription or payment
- May offer trial periods or limited free access
- Enterprise pricing common for business use
Research/Academic Databases
- Often free and open access
- May require institutional affiliation for some resources
- Open-source tools common in research communities
NGO/International Organization Databases
- Generally free public access
- May require registration
- Some data may be restricted based on purpose
