摘要： A hierarchy may be explicitly or implicitly reflected in existing data maintained external to hierarchy structures. Such hierarchies are referred to herein as a “pre-existing hierarchies”. Techniques are described herein for capturing a pre-existing hierarchy in hierarchy structures. After a pre-existing hierarchy has been captured, there exist two independent sets of data that reflect the hierarchy: the external hierarchy definition and the internal hierarchy definition. Changing either hierarchy definition changes the hierarchy. Therefore, to maintain a consistent reflection of the hierarchy, the internal hierarchy definition must be modified in response to changes made to the external hierarchy definition, and the external hierarchy definition must be modified in response to changes made to the internal hierarchy definition. Various techniques are described for maintaining consistency between the two hierarchy definitions.

摘要： A method and apparatus for processing path-based database operations is provided. According to one aspect, a path cache is maintained. For each hierarchical node that is traversed during a path-determining operation, it is determined whether a cache entry corresponding to that node is already contained in the path cache. If such a cache entry is already contained in the path cache, then the path indicated in that cache entry is used to complete the pathname for the node for which the operation is being performed. As a result, hierarchically higher nodes do not need to be traversed to complete the operation. Alternatively, if such a cache entry is not already contained in the path cache, then a cache entry for the node currently being traversed is generated and inserted into the path cache for use in subsequent path-determining operations.

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 system for evolving XML-schema-based data to conform to an evolved XML schema is disclosed. Based on an existing XML schema and an instance document that is based on the existing XML schema, an XML-schema-independent form of the instance document is generated. Based on a set of specified transformations and the XML-schema-independent form of the instance document, an evolved instance document is generated. The evolved instance document conforms to an evolved XML schema that incorporates changes to the existing XML schema. Techniques described herein are flexible enough to accommodate a wide variety of evolutions to XML schemas.

摘要翻译：层次结构可以在层次结构外部维护的现有数据中显式或隐式地反映出来。这样的层次结构在本文中称为“预先存在的层级”。这里描述了用于在层次结构中捕获预先存在的层次结构的技术。在捕获了一个预先存在的层次结构之后，存在反映层次结构的两个独立的数据集：外部层次结构定义和内部层次结构定义。更改层次结构定义会更改层次结构。因此，为了保持层次结构的一致反映，必须根据对外部层次结构定义所做的更改来修改内部层次结构定义，并且必须根据对内部层次结构定义的更改来修改外部层次结构定义。描述了用于维持两个层次结构定义之间的一致性的各种技术。

摘要： A method and apparatus for processing path-based database operations is provided. According to one aspect, a “parent row ID” column is added to a directory links table. For each row in the table, the value of the “parent row ID” column indicates the row ID, in the table, of the node that is that row's node's parent in the file hierarchy. To determine whether a particular node is within a specified path of the file hierarchy, the particular node's pathname is derived by visiting child-to-parent links indicated in the table and prepending, to the front of a pathname being constructed for the particular node, node names indicated in the visited rows. Each parent node's row in the directory links table is located using the “parent row ID” column of the child node's row. The resulting pathname is compared with the specified path to determine whether the particular node exists therein.

摘要： Techniques for servicing requests for database services include maintaining at a database server an available set of one or more database session data structures. Each database session data structure holds information to support one session of one or more requests for database services over a communication connection that persists for one or more communications from one client. A database session data structure in the available set is not associated with any client currently connected to the database server. These techniques allow a database server to more efficiently service more numerous requests for database services, such as generated by communications using a stateless protocol like HTTP.

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.
