Description
This unit describes the skills and knowledge required to implement a data store and manage data persistence using non structured query language (NoSQL) to provide automatic scaling as well as high performance and availability over semi-structured data.The unit applies to those working as senior software developers, senior back end developers or full stack developers, and responsible for managing information and communications technology (ICT) in small-to-large enterprises (SMEs).No licensing, legislative or certification requirements apply to this unit at the time of publication.
