System Properties Comparison Memcached vs. Percona Server for MySQL vs. PouchDB vs. SQLite vs. TypeDB

Editorial information provided by DB-Engines

Name

Description

In-memory key-value store, originally intended for caching

Enhanced drop-in replacement for MySQL based on XtraDB or TokuDB storage engines with improved performance and additional diagnostic and management features.

JavaScript DBMS with an API inspired by CouchDB

Widely used embeddable, in-process RDBMS

TypeDB is a strongly-typed database with a rich and logical type system and TypeQL as its query language

Primary database model

Graph DBMS
Relational DBMS

Often described as a 'hyper-relational' database, since it implements the 'Entity-Relationship Paradigm' to manage complex data structures and ontologies.
