Techniques are described for executing queries that have XPath sections that specify unmappable paths. The techniques involve splitting the unmappable paths into (1) a mappable path fragment, and (2) an unmappable path fragment. After an unmappable path has been split into a mappable path fragment and an unmappable path fragment, the XPath section is replaced with a replacement XPath section. The replacement XPath section specifies two operations: a “mappable operation” that is based on the mappable path fragment, and an “unmappable operation” that is based on the unmappable path fragment. The portion of the replacement XPath section that specifies the mappable operation is rewritten to access underlying relational structures. Consequently, when the rewritten query is executed, a smaller amount of XML data needs to be materialized to evaluate the unmappable path fragment than would otherwise have been required to evaluate the original unmappable path.

Translation architecture that facilitates translation between schema data and relational structures. The architecture includes a translation component that consumes schema data ( e . g ., an XML schema) that includes a schema structure, validates the schema structure, and persists in memory a representation of the schema as a relational format. Since schemas are shredded into tables, instance validation loads only the necessary components to perform validation. During validation, only parts of the schema that are used are loaded and cached. A schema cache stores the in-memory representation of schema optimized for instance validation. Schema components are loaded from metadata into main memory as read-only objects such that multiple users can use the in-memory objects for validation, query processing, query optimization and storage optimization of XML instance data .

A messaging server (112) provides a message store (116) for storing messages in a relational manner. A set of related messages, such as an email string between two or more people, is represented as a message container (200) having relational references to one or more submessages (210, 212, 214). The messaging server (112) processes non-relational messages sent by the server by inserting (516) tags that uniquely identify components within the message. The messaging server (112) also processes tagged or untagged non-relational messages received by the server to create (616, 618) relational counterparts in the message store (116). Relational searches can be executed on the messages in the message store (116) to perform audits or forensic analyses of the messages.
