摘要： A technique and mechanism for efficiently searching across multiple versions of a resource is provided. New operators are provided that take into account the versions of a particular resource. The query engine evaluates the new operators using either an index-based approach or a functional approach. Under an index-based implementation, a hierarchical index is traversed to find a particular resource (or resources) associated with a specified path and the version history identifier associated with the particular resource(s). A version history table containing references to all versions of the particular resource(s) are then obtained. Under the functional implementation, a link table, which contains all paths in a user's workspace, is examined to determine whether the version history identifier of a particular resource matches a version history identifier of a resource specified in the link table and whether the path to the resource in the link table is related to the path specified.

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.
摘要翻译：在多层数据服务器系统中，来自第一层的数据被缓存在中间层的中间层缓存中。来自数据的第一层的访问控制信息也缓存在中间层缓存中。缓存中间层的安全信息允许中间层对外层客户端的数据请求进行访问控制决策。

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： 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.

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： 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： 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.
