<div id="body0000001381728549"><p id="EN-US_TOPIC_0000001381728549__en-us_topic_0000001145816541_p371183032613">Both allow you to run conventional relational databases on the cloud and transfer database management loads. RDS databases are useful for OLTP, reporting, and analysis, but are less capable of handling read operations of a large amount of data (complex read-only queries). GaussDB(DWS) is useful for OLAP by reducing analysis and report workloads of large data sets by an order of magnitude, thanks to its multi-node scale and resources and optimized algorithms (<strong id="EN-US_TOPIC_0000001381728549__b14169131112333">column storage, vectorized executors, and distributed frameworks</strong>).</p>
