摘要： A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety or sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.

摘要： A method and apparatus are provided for building and using a persistent XML tree index for navigating an XML document. The XML tree index is stored separately from the XML document content, and thus is able to optimize performance through the use of fixed-sized index entries. The XML document hierarchy need not be constructed in volatile memory, so creating and using the XML tree index scales even for large documents. To evaluate a path expression including descendent or ancestral syntax, navigation links can be read from persistent storage and used directly to find the nodes specified in the path expression. The use of an abstract navigational interface allows applications to be written that are independent of the storage implementation of the index and the content. Thus, the XML tree index can index documents stored at least in a database, a persistent file system, or as a sequence of in memory.

摘要： A method and apparatus for automatically analyzing and providing feedback regarding the optimizability of a relational database query. A query developer's primary goal is to ensure that queries and DML operations are rewritten for the most efficient execution. Rewrite diagnosability captures metadata for each attempted query optimization including success or failure and the reasons for failure. The metadata is stored in association with the operators that were not removed through rewriting. Once all optimizations have been attempted and rewriting is complete, the metadata is selectively displayed based on the cost to perform the associated operation. The context of performing the operation may affect the cost. The cost may be based at least on the type of operation and where within the query tree the operation is located. A query developer may configure the database system not to execute the resulting query plan based on one or more criteria.

摘要： A method, device, and non-transitory computer-readable storage medium are provided for efficiently registering a relational schema. In co-compilation and data guide approaches, a subset of entities from schema descriptions are selected for physical registration, and other entities from the schema descriptions are not physically registered. In the co-compilation approach, a first schema description references a second schema description, and the subset includes a set of entities from the second schema description that are used by the first schema description. In the data guide approach, the subset includes entities that are used by a set of structured documents. In a pay-as-you-go approach, schema registration includes logically registering entities without creating relational database structures corresponding to the entities. A database server may execute database commands that reference the logically registered entities. A request to store data for the entities may be executed by creating relational database structures to store the data.

摘要： A method and apparatus is provided for efficiently searching and navigating XML data stored in a relational database. When storing a collection of XML documents, certain scalar elements may be shredded and stored in a relational table, whereas unstructured data may be stored as a CLOB or BLOB column. The approach includes identifying a reference address to within an XML tree index entry and storing the address in an xmltable index. The tree index entry allows for navigation in all axes. A path-based expression may be evaluated in the context of the reference address of the LOB. The result of the evaluation identifies another XML tree index entry containing a LOB locator used to retrieve the content from the document. The tree index, node index, and secondary function indexes are used together to enhance the performance of querying the XML data.

摘要： A database server provides a partitioned table with a corresponding locally partitioned index. When a request is made to load data into the table by an application, a table partition, along with a corresponding index partition, is created for the application. The corresponding index partition in marked as asynchronously maintained, allowing other index partitions to be used by the query optimizer in formulating query plans for other table partitions. Once the loading of data is complete, a synchronization operation is called with the result of conforming the data in the asynchronously maintained index partition with its corresponding table in which the data was loaded. Once the data in the corresponding table partition and the data in the asynchronously maintained index partition are synchronized, the asynchronously maintained index partition is marked as synchronously maintained.

摘要： 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, techniques perform additional analysis to determine a minimal common ancestor. Within the context of a minimal common ancestor, techniques determine the maximum number of times an element may occur in the schema. In a choice content model, the largest maximum occurrence value is selected. In other content models, the maximum occurrence value is determined by adding together the occurrence values for the repeated elements. Then, when an object relational table is generated for the XML schema, the maximum number of times that an element appears in the schema is this value. Techniques retain the advantages of object relational storage, even after a schema evolution.

摘要： One embodiment of the present invention provides a system that implements a security policy in a database. During operation, the system receives a request associated with a set of objects in the database. Next, the system obtains a set of access control lists (ACLs) associated with the database, wherein a respective ACL specifies one or more access privileges associated with a user or user group, and wherein a respective ACLs is not specific to a particular object in the database. The system then evaluates the ACLs to obtain a set of ACL results associated with the request and processes the request by applying the set of ACL results to the objects without evaluating the ACLs repeatedly for each of the objects.
