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 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.
摘要翻译：多个资源中的每一个的版本历史被存储在表中。每个资源的版本历史包括用于资源的一个或多个值的集合，其中资源的版本历史中的每个值指示资源在资源的特定版本中具有的值。响应于执行导致受到唯一性约束的给定资源具有特定值的操作的请求，基于是否具有给定资源的任何资源的任何版本的任何版本是否被确定是否违反唯一性约束具体的价值。如果给定资源以外的任何资源的任何版本具有特定值，则唯一性约束被确定为违反。唯一性约束不被存在具有特定值的给定资源的版本所抵触。

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-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： Techniques are provided for facilitating uniform access control to data managed by a database server that can emulate hierarchically organized systems, whether the data is accessed through hierarchical or relational access mechanisms. A database server that can emulate hierarchically organized systems uses separate relational or object-relational database tables to store the content of the resources that belong to a hierarchy (the “content structures”) and information that captures the hierarchy (the “hierarchy structures”). Both types of structures contain access control data that define consistent user access privileges. To determine access privileges for a user requesting access to data in the database, access control information is accessed in the hierarchy structures when the request is made through the hierarchical access mechanism, or accessed in the content structures when the request is made through a relational access mechanism. Access control is consistent between the hierarchical or relational access mechanisms because access through either is governed by user access data that reflects the same privileges.
摘要翻译：提供了技术，用于促进对数据库服务器管理的数据的统一访问控制，数据库服务器可以模拟分层组织的系统，无论数据是通过分级或关系访问机制访问的。可以模拟分级组织的系统的数据库服务器使用单独的关系或对象关系数据库表来存储属于层次结构的资源的内容（“内容结构”）和捕获层次结构的信息（“层次结构”）。这两种类型的结构都包含定义一致的用户访问权限的访问控制数据。为了确定请求访问数据库中的数据的用户的访问权限，当通过分层访问机制进行请求时，在层次结构中访问访问控制信息，或者当通过关系访问进行请求时在内容结构中访问访问控制信息机制。访问控制在分级或关系访问机制之间是一致的，因为通过任何一个访问控制的用户访问数据反映相同的权限。

摘要： A method and system for the in-place evolution of XML schemas is disclosed. To automatically evolve an existing XML schema, a schema evolver receives both an existing XML schema and an XML document as input. The XML document indicates changes to be made to the existing XML schema. Based on the existing XML schema and the XML document, the schema evolver evolves the existing XML schema into a new XML schema that incorporates the changes indicated in the XML document. According to one aspect, the schema evolver generates one or more SQL statements based on the new XML schema. The SQL statements, when executed by a database server, cause the database server to evolve database structures that were based on the formerly existing XML schema so that the database structures conform to the new XML schema. This is accomplished “in place,” without copying the data in the database structures.
摘要翻译：公开了一种用于XML模式的就地演化的方法和系统。为了自动演进现有的XML模式，模式演进器接收现有的XML模式和XML文档作为输入。 XML文档指示对现有XML模式进行的更改。基于现有的XML架构和XML文档，架构演进者将现有的XML架构演变为新的XML架构，其中包含XML文档中指示的更改。根据一个方面，模式演进者基于新的XML模式生成一个或多个SQL语句。 SQL语句在由数据库服务器执行时，会导致数据库服务器发展基于以前存在的XML模式的数据库结构，以便数据库结构符合新的XML模式。这完成了“到位”，而不复制数据库结构中的数据。
