XML:
XML stands for “Extensible Markup Language”, provides independent tool for describing data.
- XML data is also referred as self-describing, which means the structure of the data is fixed with the data. Therefore, no need to pre-build the structure of the data when it arrives to store in the
database . - It is a markup language like HTML, contains a set of rules to format the documents that can be read by both humans and machines.
- It is an open standard to create formatted documents and share the structured data using internet or corporate networks.
