Title: Incremental Validation of Key and Keyref Constraints
Authors: Sharon Krisher and Oded Shmueli
PDFCS-2006-01.pdf
Abstract: We suggest simple update operations on XML documents. These operations may change the value of a simple-type node, or change several values transactionally. We present efficient algorithms for checking the validity of such operations with respect to key and keyref constraints (XML Schema identity constraints). We discuss the implementation of the algorithms for checking the validity of single/multiple value changes, and present experiments that show its superiority over validation from scratch.
