Notes

  • Key-value database, or key-value store, is a data storage paradigm that allows you to store opaque data collection with an associated key.

    • You restore the records by their keys.
  • Each key uniquely identifies a record.

  • Each collection may have different fields.

  • It works differently from relational databases (RDB) because RDBs predefine the data structure in the database as a series of tables containing well-defined data types.

  • It offers flexibility because you can store any object structure.

  • It uses less memory to store the same database compared with RDB.

  • Examples of key-value databases:
