A new sub-document versioning method for record storages of XML documents which uses virtual cutting points to ensure that a search tree is able to support multiple versions of sub-documents and provide efficient mechanisms for XML updating. Record boundaries and virtual cut points divide the two-dimensional space, the horizontal axis representing node identifiers in document order and vertical axis representing version numbers, into rectangles. The bottom corner of the rectangle is used to represent the rectangles and the corresponding information of the corner is added to the search tree index.

A method for publishing relational data as XML by translating XML queries into queries against an relational database. Conversion of the relational database into an XML database is not required. Each relational table is mapped to a virtual XML document, and XML queries are issued over these virtual documents. An XML query is parsed and transformed into a language-neutral intermediate representation, which is a sequence of operations describing how the output document is derived from the underlying relational tables. The intermediate representation is then translated into an SQL query over the underlying relational tables and into instructions for a tagger. The SQL query is executed, and the SQL query results are then fed into the tagger, which follows tagger instructions to generate the marked up output.

Disclosed is an XML database duplicating apparatus and method capable of providing an effective application service without interruption at a low cost in the diverse Internet environments by copying an XML document of a database system mounting an XML processing technique to another remote server. When the XML document stored in a database of the original server is copied to databases of copied servers, the structure and attribute information included in the XML document are maintained as they are, and thus the respective copied servers can support the searches based on the contents and the attribute provided by an XML query language and disperse users' queries concentrated to the original server to the respective copied servers, so that the service request for application programs can be processed.

A system and method for concurrency control of hierarchically structured data is provided. Lock requests on a target node are processed by exploiting ancestor-descendant information encoded into prefix encoded node identifiers (IDs). A set of implicit locks on ancestor nodes along a path from an immediate parent of a target node to a root node is derived from an explicit lock request on a target node. A logical lock tree describing existing lock modes for ancestor nodes is consulted to determine compatibility with the derived set of implicit locks. If existing lock modes for ancestor nodes are compatible with the derived set of implicit locks, a lock request on a target node is granted. Otherwise, the lock request is denied. A lock release request follows the reverse process; a target node in a particular transaction is released, as are subsequent locks on its ancestors made by the same transaction.

A method of generating a searchable database system for storing and querying Extensible Markup Language (XML) documents is disclosed. A Document Type Description (DTD) associated with one or more XML documents is analyzed to determine a scope of XML documents defined by the DTD. A first set of elements associated with the DTD is identified. The first set of elements is mapped to a relational database. A second set of elements associated with the DTD to be stored in an XML database is identified. A collection of classes is created such that each class defines an object schema. The classes are mapped to a set of corresponding tables, and foreign and primary keys associated with the corresponding tables are identified.

The invention discloses a method and a system for realizing data consistency. A data access assembly receives user messages, dynamic structured query language (SQL) is generated according to the user messages, an extensive makeup language (XML) database configuration file is connected with a relationship database and obtains data, and then, the data is transmitted to an application layer; an overall buffer data set is inquired according to the overall property data access assembly object name and the data obtaining object name, the data is returned to the data access assembly when the data exists, and the data is transmitted to the application layer by the data access assembly; and according to the data access assembly object name and the data obtaining object name, an overall buffer memory assembly is created when no data exists, and the obtained data dynamic SQL, the data access assembly object name and the data obtaining object name are transmitted to the buffer memory assembly. The method and the system solve the problem of data consistency between a server buffer memory and the relationship database and have the advantages that the effectiveness of the server buffer memory data is ensured, the connection access to the relationship database is reduced, the access speed is accelerated, and the access efficiency is improved.
