There are similarities between XML and databases in terms of storage, querying, and APIs. Storing XML in databases allows for indexing, efficient storage, and support for multiple users, transactions, security, and locking. XML documents can be stored in databases either as data-centric or document-centric documents. Data-centric XML is usually generated by systems and element order does not matter, while document-centric XML has unpredictable structure and element order is important. Native XML databases store XML as the fundamental unit, while XML-enabled databases convert XML to a database model, which can result in loss of information like element order. Web services use XML languages like SOAP and WSDL to enable interoperable machine-to-machine communication over
