  1. Relational (MySQL, PostgreSQL)
    πŸ”‘ For: Structured data, complex queries, ACID compliance
    πŸ’Ό Use case: Financial systems, ERP applications

  2. Key-Value (Redis, DynamoDB)
    πŸ”‘ For: Ultra-fast, simple data lookups
    πŸ’Ό Use case: Caching, session management

  3. Document (MongoDB, CouchDB)
    πŸ”‘ For: Semi-structured data in JSON-like formats
    πŸ’Ό Use case: Content management, user profiles

  4. Graph (Neo4j, ArangoDB)
    πŸ”‘ For: Complex data relationships
    πŸ’Ό Use case: Social networks, recommendation engines

  5. Wide-Column (Cassandra, HBase)
    πŸ”‘ For: Large-scale, high-write-throughput scenarios
    πŸ’Ό Use case: IoT sensor data, time-series for large systems

  6. In-Memory (Redis, Memcached)
    πŸ”‘ For: Microsecond response times
    πŸ’Ό Use case: Real-time analytics, caching layers

  7. Time-Series (InfluxDB, TimescaleDB)
    πŸ”‘ For: Efficient time-stamped data handling
    πŸ’Ό Use case: Monitoring systems, financial trading

  8. Object-Oriented (db4o, ObjectDB)
    πŸ”‘ For: Data mirroring object-oriented structures
    πŸ’Ό Use case: CAD/CAM systems, scientific simulations

  9. Text-Search (Elasticsearch, Solr)
    πŸ”‘ For: Full-text search and complex text queries
    πŸ’Ό Use case: Search engines, log analysis

  10. Spatial (PostGIS, SpatiaLite)
    πŸ”‘ For: Geographic data and location services
    πŸ’Ό Use case: GIS applications, location-based recommendations

  11. Blob (Amazon S3, Azure Blob Storage)
    πŸ”‘ For: Large binary object storage
    πŸ’Ό Use case: Content delivery, data lakes

  12. Ledger (Hyperledger Fabric, Amazon QLDB)
    πŸ”‘ For: Immutability and audit trails
    πŸ’Ό Use case: Financial records, supply chain tracking

  13. Hierarchical (IBM IMS, Windows Registry)
    πŸ”‘ For: Tree-like structured data
    πŸ’Ό Use case: File systems, organization charts

  14. Vector (Singlestore, Chroma)
    πŸ”‘ For: High-dimensional vector data, similarity searches
    πŸ’Ό Use case: ML models, recommendation systems

  15. Embedded (SQLite, Berkeley DB)
    πŸ”‘ For: Local data storage within applications
    πŸ’Ό Use case: Mobile apps, edge computing devices

Pro Tip: Modern apps often benefit from using multiple database types. Don't hesitate to mix and match for the best results!
