| 20080082560 | Implementation of backward compatible XML schema evolution In-place XML schema evolution occurs by evaluating an existing XML schema in a database system to see if it is compatible with a new XML schema. To determine if the old schema is compatible with the new schema, a lock-step traversal is performed on the two schemas. Each... | 04/03/2008 |
| 20080071812 | Evolution of XML schemas involving partial data copy 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 ... | 03/20/2008 |
| 20080065654 | Management of complex XML schemas in a database system Techniques manage the presence of repeated constructs within a complex type at the time of schema registration. At registration, techniques detect repeated elements in the XML schema and analyze whether the repeated elements are from the same complex type. If so, techni... | 03/13/2008 |
| 20070083542 | Flexible storage of XML collections within an object-relational database 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 varie... | 04/12/2007 |
| 20070083529 | Managing cyclic constructs of XML schema in a rdbms A database system automatically detects a cyclic construct in a XML schema, determines a database representation for the cyclic construct, and maps the XML schema and elements involved in the cyclic construct to the database representation. ... | 04/12/2007 |
| 20070038649 | Flexible handling of datetime XML datatype in a database system 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 syste... | 02/15/2007 |
| 20060179068 | Techniques for efficiently storing and querying in a relational database, XML documents conforming to schemas that contain cyclic constructs 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)... | 08/10/2006 |
