This paper describes an XML query language called XML-QBE, which can be used to both query and update XML documents and databases. The language itself has a simple XML form, and uses a query by example paradigm. This language was designed as a middleware layer between UML data models and backend database schemas, as part of a solution to the distributed, heterogeneous data-base problem and legacy database problem. Because the XML layer is derived from UML, XML-QBE is object-oriented. Queries and updates have a very similar form, and the form itself is XML. Therefore this language is also easy to process and analyze. We describe the language, the rationale, and our solution architecture.Read the full paper here: https://link.springer.com/chapter/10.1007/978-3-540-39597-3_32
