Recent years have perceived a theatrical increase in the fame and acceptance of XML-eXtensible Markup Language. This impulsive growth is determined by its ability to offer a standardized, extensible means of involving semantic content within documents describing semi-structured data in database management systems. It enables to address the limitations of existing markup languages and support data exchange in relational databases. Most of the information systems that work on relational databases today are to suffer a lack of both performance and inter-operability or migration issues especially when the information systems work on different databases at different nodes of operations. The XML Native Databases also known as NXD cater to this issue, as XML has emerged into the most powerful markup language that can effectively store, carry or even transform data and its unique feature of encoding independent, platform independent nature. Hence, the paper discusses the survey of earlier works and addresses the need for XML databases as compared to relational databases and further, an insight into the document centric feature of the NXD required by present day use case scenarios.
