DBMS > Adabas vs. IRONdb vs. Microsoft SQL Server vs. NebulaGraph vs. RRDtool

System Properties Comparison Adabas vs. IRONdb vs. Microsoft SQL Server vs. NebulaGraph vs. RRDtool

Editorial information provided by DB-Engines

Name

IRONdb seems to be discontinued. Therefore it is excluded from the DB-Engines Ranking.

Description

OLTP - DBMS for mainframes and Linux/Unix/Windows environments

used typically together with the Natural programming platform

A distributed Time Series DBMS with a focus on scalability, fault tolerance and operational simplicity

Microsofts flagship relational DBMS

A distributed, linear scalable, high perfomant Graph DBMS

Industry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database.

The data is stored in a circular buffer, thus the system storage footprint remains constant over time.
