摘要： To associate XML data objects (“child objects”), stored in rows of relational or object-relational tables, with the appropriate XML data objects (“parent objects”) from which the child objects descend, tables that contain child objects (“out-of-line” tables) are constructed with an additional column. In one embodiment, this column stores values that identify the root objects, in the appropriate table, from which the respective child objects descend. Hence, the root object from which any given object descends is traceable by following the respective value back to the corresponding root object. In one embodiment, this column stores values that identify the complete XML hierarchical path, through multiple tables, back to the root object from which the respective child objects descend. Consequently, XML query language queries against XML documents stored in such tables can be rewritten as SQL queries against the data in the tables, even in the presence of cyclic constructs.

摘要： A database server determines, on an element-level of granularity, what form of VARRAY storage to map collections of elements defined by a XML schema. A collection element may be mapped to an in-line VARRAY or an out-of-line VARRAY. The determination may based on a variety of factors, including the database type mapped to the collection element, database limitations that limit the form storage for certain database types, and annotations (“mapping annotations”) embedded within that XML schema that specifying a database type for database representation of a collection element or a form of VARRAY storage.

摘要： A database server registers an XML schema and determines a database representation for the XML schema and mapping information, determining what database types should be used to represent an XML schema and/or how instances of the XML schema are stored by a database system. The mapping information indicates the mapping between the constructs declared in the XML schema and the constructs included in the appropriate database representation. The XML schema may contain annotations that describe one or more properties of a database representation of an XML date-time type. Based on the annotations, the database determines an appropriate database representation and generates mapping information mapping the declaration of the XML date-time type of the XML schema to the constructs of the database representation.

摘要： XML schema evolutions can be performed on an XML-type database using partial data copy techniques. The partial data copy techniques provide mechanisms to identify a minimal set of data in the database that needs be copied out in order for schema evolution operations to occur. Identifying the minimal set of data involves comparing an existing XML schema to a new XML schema and determining the differences between the two schemas. Based on those differences, a minimal set of data can be determined. That data can then be copied to a temporary storage location, while the XML schema and its associated database structure are updated to conform to the new XML schema. Then, the minimal set of data is copied back into the modified database structure.

摘要： A version history of each of a plurality of resources is stored in a table. The version history for each resource comprises a set of one or more values for the resource, wherein each value in the version history of a resource indicates the value that the resource had in a particular version of the resource. In response to a request to perform an operation that causes a given resource that is subject to a uniqueness constraint to have a particular value, it is determined whether the uniqueness constraint is violated based on whether any version of any resource other than the given resource has the particular value. The uniqueness constraint is determined to be violated if any version of any resource other than the given resource has the particular value. The uniqueness constraint is not violated by existence of a version of the given resource that has the particular value.

摘要： A technique and mechanism for efficiently searching across multiple versions of a resource is provided. New operators are provided that take into account the versions of a particular resource. The query engine evaluates the new operators using either an index-based approach or a functional approach. Under an index-based implementation, a hierarchical index is traversed to find a particular resource (or resources) associated with a specified path and the version history identifier associated with the particular resource(s). A version history table containing references to all versions of the particular resource(s) are then obtained. Under the functional implementation, a link table, which contains all paths in a user's workspace, is examined to determine whether the version history identifier of a particular resource matches a version history identifier of a resource specified in the link table and whether the path to the resource in the link table is related to the path specified.
