Aisha Bukar lays out how XML works in a pair of relational platforms:
XML (Extensible Markup Language) may no longer dominate modern web APIs the way it once did, but it still plays a critical role in many enterprise systems. Financial institutions, publishing platforms, healthcare systems, government agencies, and large legacy applications continue to rely heavily on XML for structured data exchange and long-term interoperability.
XML also remains deeply embedded in technologies such as SOAP-based APIs, enterprise messaging systems, configuration files, and document-centric workflows where strict structure and validation are essential. This is largely because, unlike lightweight formats such as JSON, XML was designed to handle complex hierarchical documents, namespaces, schemas, and mixed content.
Read on to see how the two open-source relational database platforms handle XML data.
