摘要： A method and system are provided for maintaining an XML index in response to piece-wise modifications on indexed XML documents. The database server that manages the XML index determines which nodes are involved in the piece-wise modifications, and updates the XML index based on only those nodes. Index entries for nodes not involved in the piece-wise modifications remain unchanged.

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： Techniques are provided for accessing and storing files within a virtual folder. A virtual folder is a folder that is logically a part of a hierarchical folder structure of a file system repository, but the contents of the virtual folder are not physically stored in the file system repository. A client may issue, to an access mechanism, a request to perform a file operation on a file in a virtual folder. The access mechanism, which may be a database server or a component therein, may perform the file operation on the file in the virtual folder as if the file was stored in a particular folder within the hierarchical folder structure implemented by the file system repository. Advantageously, files may be physically stored outside of the file system repository, but still be a part of the hierarchical folder structure implemented by the file system repository.

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： Business logic is integrated within a repository through the use of “resource configurations.” A resource configuration is a unit of business logic that is supplied by a user to the repository and associated with a particular directory and/or a resource. Each resource configuration contains one or more configuration items that each defines and/or expresses one or more business rules for managing a resource associated with the resource configuration.

摘要： A method and apparatus for performing an action in response to a file system event is provided. According to one aspect, sets of “event listeners” are associated with a file hierarchy and/or the nodes thereof. Each event listener contains a set of “event handlers.” Each event handler corresponds to a separate type of event that may occur relative to the file hierarchy's nodes. When an event is going to occur relative to the hierarchy or a node thereof, all event listeners that are associated with that hierarchy/node are inspected to determine whether those event listeners contain any event handlers that correspond to the event's type. Those event handlers that correspond to the event's type are placed in an ordered list of event handlers to be invoked. As the event handlers in the list are invoked, programmatic mechanisms that correspond to those event handlers are executed to perform customized user-specified actions.

摘要： A method and apparatus for efficiently maintaining XML index structures in a database system is provided. Instead of immediately synchronizing the XML index structures for every change submitted to the database, the changes are stored in a PENDING table. The XML index structures are periodically synchronized, based on certain criteria or at a user's discretion. Between synchronizations, the XML index structures may be in stale mode or current mode. If in stale mode, a request to access indexed information will use the XML index structures to find the desired indexed information without checking the PENDING table. If in current mode, a request to access indexed information will search the XML index structures and also check the PENDING table to determine 1) whether the indexed information has been updated or deleted, and 2) whether information relevant to the request has been inserted or updated.

摘要： Techniques for supporting access controls on application-specific operations performed by an application include receiving first data at a server distinct from the application. The first data describes a first set of privileges for performing a first set of application-specific operations. Second data is also received at the server. The second data associates a first user of the application with a privilege in the first set of privileges. In response to receiving a request at the server from the application, it is determined whether a particular user may have the application perform a particular application-specific operation based on the first data and the second data. The request indicates the particular user and the particular application-specific operation. A response is sent to the application. The response indicates whether the particular user may have the application perform the particular application-specific operation.

摘要： A method and system are provided for extracting a valid, self-contained fragment for a node in a XML document stored in a database management system. An XML index is used to identify a location in which XML fragment data corresponding to the node is located. Ancestors of the node are identified and examined for any information needed for the proper interpretation of the fragment. If an ancestor node contains such needed information, this information is patched into the XML fragment to ensure that the fragment is a valid, self-contained XML fragment.

摘要： Techniques are provided for indexing XML documents. According to one embodiment, a PATH table created for storing one row for each indexed node of the XML documents. The PATH table row for a node includes (1) information for locating the XML document that contains the node, (2) information that identifies the path of the node, and (3) information that identifies the position of the node within the hierarchical structure of the XML document that contains the node. If the node is associated with the value, then the PATH table row for the node may also include the value. Use of the PATH table to answer XPath queries is facilitated by secondary indexes.
