System Properties Comparison IBM Db2 Event Store vs. Microsoft Access vs. MySQL vs. OpenSearch vs. Oracle NoSQL

Editorial information provided by DB-Engines

Name

Description

Distributed Event Store optimized for Internet of Things use cases

Microsoft Access combines a backend RDBMS (JET / ACE Engine) with a GUI frontend for data manipulation and queries.

The Access frontend is often used for accessing other datasources (DBMS, Excel, etc.)

Widely used open source RDBMS

A distributed, RESTful search and analytics engine forked from Elasticsearch and based on Apache Lucene

A multi-model, scalable, distributed NoSQL database, designed to provide highly reliable, flexible, and available data management across a configurable set of storage nodes

Primary database model

Event Store
Time Series DBMS

Relational DBMS

Key/Value like access via memcached API

Search engine

Document store
Key-value store
Relational DBMS

Secondary database models

Document store
Spatial DBMS

Vector DBMS
