摘要： A mechanism for querying a label-aware index in the context of versioning is provided. The key of the label-aware index is a composite key and includes a unique label identifier, corresponding to a specific label, and the key of the original index, which key itself may be a composite key. The label-aware index may be implemented as an index-organized table. The label-aware index is organized on disk first by the label identifier and then by the original index key so that queries of versions of resources within a particular label are as efficient as queries on an index of an unversioned repository with the same number of resources.
摘要翻译：提供了一种用于在版本控制的上下文中查询标签感知索引的机制。标签感知索引的密钥是复合密钥，并且包括对应于特定标签的唯一标签标识符和原始索引的密钥，该密钥本身可以是复合密钥。标签感知索引可以被实现为索引组织表。标签感知索引首先由标签标识符组织，然后由原始索引键组织，以便特定标签内的资源版本的查询与具有相同数量资源的未版本化存储库的索引上的查询一样有效。

摘要： In a multi-tier data server system, data from the first tier is cached in a mid-tier cache of the middle tier. Access control information from the first tier for the data is also cached within the mid-tier cache. Caching the security information in the middle tier allows the middle tier to make access control decisions regarding requests for data made by clients in the outer tier.

摘要： A shared workspace is associated with a group of users who share the workspace, which isolates a set of shared resources from other resources stored in a repository that supports versioning of resources. The content of a shared workspace is maintained using a set of shared references, to the set of resources associated with the shared workspace. A virtual workspace is created for a user by generating a personal mapping for the user, where the personal mapping indicates which resources from the set of shared resources the user has made personal, e.g., by checking out such resources from the repository. If the user submits a query on the repository, the particular version of each resource involved in the query is readily determinable from the shared workspace and the user's virtual workspace.

摘要： Evaluation of workspace-local queries on a repository that supports versioning is enabled by tracking which versions of resources that are stored in the repository are associated with particular workspaces. A mapping is created and maintained for each workspace and each workspace-enabled table, i.e., a repository table that supports multiple versions of resources in the table. The mapping, such as a bit vector, is indexed by resource identifier. A set bit indicates that a particular resource version that corresponds to the bit is associated with the particular workspace. Therefore, the mapping indicates which rows in the workspace-enabled table are in the particular workspace. Index-based and functional evaluation schemes may utilize the per workspace, per table mapping to evaluate queries on the versioned repository. A new operator (IN_WORKSPACE) is introduced, through which an evaluation routine is invoked to determine whether or not a particular row maps to a particular workspace.

摘要： 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 instruction in the old schema is compared to instructions in the new schema. Detected differences between the two schemas are evaluated to determine if existing XML documents are still compatible with the new schema. If they are, then an in-place schema evolution operation can take place. The in-place schema operation basically, involves appending the updated object information to the underlying object type and preserving the order of elements in a document by storing element mapping information on disk.

摘要： Efficient evaluation of resource version history queries is enabled by using a data container storing records corresponding to links between successive versions of a resource. The records include: (a) a record identifier, (b) a predecessor identifier, (c) a successor identifier, (d) a predecessor rowset, which comprises the record identifier of each record in which the predecessor identifier in this record is the successor identifier, and (e) a successor rowset, which comprises the record identifier of each record in which the successor identifier in this record is the predecessor identifier. Depending on the nature of a request, a record is identified in which a particular version is identified by either the predecessor identifier or the successor identifier. Either the predecessor or successor rowsets are recursively read, while the predecessor or successor identifiers corresponding to each record read are added to a result set, thereby forming the ancestor or descendant version history.
摘要翻译：通过使用存储与资源的连续版本之间的链接相对应的记录的数据容器来启用资源版本历史查询的有效评估。记录包括：（a）记录标识符，（b）前导标识符，（c）后继标识符，（d）前置行集合，其包括每个记录的记录标识符，其中该记录中的前身标识符是后续标识符，以及（e）后继行集，其包括其中该记录中的后继标识符是前导标识符的每个记录的记录标识符。根据请求的性质，识别一个记录，其中特定版本由前导标识符或后续标识符标识。前导或后继行集是递归读取的，而与读取的每个记录相对应的前导或后继标识符被添加到结果集中，从而形成祖先或后代版本历史。
