摘要： Techniques are provided for creating object-oriented materialized views. The object-oriented materialized views may be object materialized views or object-relational materialized views. The base tables may be object tables, object relational tables, or relational tables. The object-oriented materialized views may be refreshed, fully or incrementally. When an object-oriented materialized view is created, refresh code is generated for it. Through the use of object-oriented materialized views, users gain both the efficiency of materialized views and the power of the object-oriented paradigm.

摘要： Techniques are provided for processing, within a database server, a database statement, where at least one subtask required by the database statement is to be executed in parallel by a slave set. The database server determines whether the database statement includes an external expression, relative to the subtask, that (a) produces information that is required by slave processes in the slave set in order to perform the subtask, and (b) is not to be evaluated by each slave process in the slave set. During execution of the statement, if the database statement includes an external expression, then one or more external values are generated by causing the external expression to be evaluated, and the one or more external values are communicated to slaves of the slave set to allow the slave processes to perform respective portions of the subtask in parallel, without requiring each slave of the slave set to evaluate the external expression.

摘要： Systems and methods that aggregate memory capacity of multiple computers into a single unified cache, via a layering arrangement. Such layering arrangement is scalable to a plurality of machines and includes a data manager component, an object manager component and a distributed object manager component, which can be implemented in a modular fashion. Moreover, the layering arrangement can provide for an explicit cache tier (e.g., cache-aside architecture) that applications are aware about, wherein decision are made explicitly which objects to put/remove in such applications (as opposed to an implicit cache wherein application do not know the existence of the cache).

摘要： Techniques for exchanging data are provided herein. An “open” data type is established on a computer system to define the structure of data. The open data type includes one or more predefined properties, and enables one or more extension properties to be optionally included. Data that is defined according to the open data type includes data values for the predefined properties, and may optionally include data values for extension properties. A second computer system may consider the extension properties to be extension properties or predefined properties of a data type known at the second computer system. In this manner, the type system that is used to exchange data between nodes need not necessarily be commonly known among the nodes, and/or may be dynamically modified, even for a particular data instance. Furthermore, queries may be performed against the data that query against the predefined properties and/or extension properties.

摘要： The claimed subject matter relates to an architecture that can facilitate an incremental approach to an Object-Relational mapping solution. The architecture can provide a rich data model that is defined at the value layer. The rich data model can expose an interface that conforms with the interfaces exposed by common storage-specific data providers. The architecture can extend common storage-specific data provider to support common command representations, and provide entity services that work in terms of the rich data model as well as object services such as identity management, updating and change tracking.

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.
摘要翻译： 提供了一种用于处理基于路径的数据库操作的方法和装置。 根据一个方面，将“父行ID”列添加到目录链接表。 对于表中的每一行，“父行ID”列的值表示表中该行的文件层次结构中该节点的父节点的行ID。 为了确定特定节点是否在文件层次结构的指定路径内，特定节点的路径名是通过访问表中指示的前后的子对象链接导出到为特定节点构建的路径名的前面， 访问行中指示的节点名称。 目录链接表中的每个父节点的行都使用子节点行的“父行ID”列进行定位。 将得到的路径名与指定的路径进行比较，以确定特定节点是否存在于其中。

摘要： Techniques for executing database commands include receiving a database command that includes an XML component operation that operates on an XML construct that is based on a first set of one or more relational database constructs. It is determined whether the XML component operation can be transformed to a relational database operation on a particular set of one or more relational database constructs of the first set, which does not involve the XML component operation. If it is determined that the XML component operation can be transformed, then the XML component operation is rewritten as a particular relational database operation that operates on the particular set and that does not involve the XML component operation. The particular relational database operation is evaluated. In another aspect, techniques include determining a primitive set of XML generation operations and replacing non-primitive XML generation operations with one or more operations from the primitive set.
