    摘要： A system and method are provided for modeling structured, semi-structured, and unstructured data all within a single instance of a user defined type (UDT) within a database store. In particular, the XML data model is extended to fields of a UDT. As a result, the properties of the XML data model—such as document order and document structure—can be preserved within instances of a UDT. Moreover, code representing object behavior (i.e., methods that can be invoked on an object in managed code) can be added to the UDT to operate on an XML field, as well as non-XML fields of the UDT. This enables a framework for adding business logic to XML data. The content model of the XML data can be optionally described using XML schema documents associated with the XML fields of the UDT.

    摘要翻译： 提供了一种系统和方法，用于在数据库存储内的用户定义类型（UDT）的单个实例中对结构化，半结构化和非结构化数据进行建模。 特别地，XML数据模型扩展到UDT的字段。 因此，XML数据模型的属性（如文档顺序和文档结构）可以在UDT的实例中保留。 此外，可以将代表对象行为的代码（即，可以在托管代码中的对象上调用的方法）添加到UDT以对XML字段以及UDT的非XML字段进行操作。 这使得可以将业务逻辑添加到XML数据中。 可以使用与UDT的XML字段相关联的XML模式文档来可选地描述XML数据的内容模型。

    摘要： Various embodiments of the present invention are directed to a database with an extensible type system for at least one user-defined type that comprises information for describing its structure as well as information for describing an inheritance relationship between itself and another user-defined type (either a subtype or a supertype/base type). For certain embodiments, the user-defined type is defined in something other than Sequential Query Language (SQL) statement such as, for example, a Common Language Runtime (CLR) statement, a statement in C, C++, and C# (“C-sharp”), and/or a visual basic statement. In any event, several embodiments are further directed to a system wherein the database is aware of the inheritance relationship between two user-defined types by an explicit registration of the user-defined types with said database.

    摘要： A technique for representing the structure of hierarchically-organized data in a non-hierarchical data structure, such as a relation. The hierarchically-organized data is represented as a tree, and each node in the tree is assigned a position identifier that represents both the depth level of the node within the hierarchy, and its ancestor/descendant relationship to other nodes. The data represented by each node, as well as its position identifier, is stored in a row of a relational database, thereby capturing the hierarchical structure of the data in such relational database. A technique is provided for the compressed storage of position identifiers in a format that allows an efficient bytewise comparison of position identifiers to determine relative order and ancestry.

    摘要： A new persistence format for storing objects of a user defined type in a database store enables information about the structure of the type to be communicated to the store. This information enables a number of store optimizations, including direct structural access to members of the type. Specifically, metadata is exchanged between the type implementer and the data store. The store uses the metadata to determine the storage layout for instances of the type. With this information, the store is able to detect access patterns that can be optimized to directly operate over the storage representation without hydration (deserialization) the object.

    摘要： The present invention the is directed to systems and methods for hosting the CLR in a DBMS in order to achieve reliability, scalability, security, and robustness for enabled DBMS programming features. Integrating the CLR with a DBMS enables programming features in the database such as stored procedures, functions, triggers, types, and aggregates to be written in any of the programming languages that are compiled into IL code supported by the CLR. For the various embodiments of the present invention, the CLR is hosted inside the DBMS and, instead of making requests directly to the server operating system, the CLR instead interfaces with the DBMS via DBMS APIs for such requests, and only the DBMS directly interfaces with the server operating system to access the server.
