ABIDE

Sonic Consciousness in Hindu India approaches to XML (as well as object-oriented) constraints. A pleasing property of this model theory is that it offers specific requirements for semantically acceptable evolution of these sophisticated schemas and their databases.

Updates and Incremental Validation of XML Documentslt is checked first (without any change on the original document). Validation tests are performed incrementally, ., only the validity of the part of the document directly affected by the update is checked. Changes to the original document are effectively performed . when the update is accepted.

A General Framework for Estimating XML Query CardinalityWR queries, hence allowing the model designer to concentrate her efforts on the development of adequate and accurate, while concise, statistic summaries for XML data. The framework can also be used for extending existing models to a wider class of XML queries.

Sonic Consciousness in Hindu Indiapaper introduces M.ORM., a model for describing meet-in-the-middle mappings between object schemas and relational schemas, to support the transparent management of object persistence by means of relational databases.
