Answer from AI
Modern applications use various types of data storage systems depending on requirements for speed, volume, data structure, and accessibility. Main types:
- Relational databases (SQL): store data in tables with a clear schema. Examples: PostgreSQL, MySQL, SQLite.
- Document-oriented databases (NoSQL): store data in document formats (usually JSON-like). Examples: MongoDB, CouchDB.
- Key-value stores: simple databases for quick access by key. Examples: Redis, Memcached.
- Columnar databases: optimized for analytics and processing large volumes of data. Examples: Apache Cassandra, HBase.
- Graph databases: for storing and processing graphs and relationships. Examples: Neo4j, JanusGraph.
- File systems and object storage: for storing large files and binary data. Examples: Amazon S3, Google Cloud Storage.
The choice depends on the specific application tasks and data requirements.
