摘要： Methods, systems, and computer-readable media are disclosed for event processing with a query based on a reusable XML query template. A particular method includes receiving a plurality of events from a source and generating a plurality of event objects based on the plurality of events. A query represented by an XML file based on a reusable XML query template is executed with respect to the plurality of event objects to produce a plurality of result objects. Each result object is produced based on an application of at least one operator of the query. A plurality of results is generated based on the plurality of result objects, and the plurality of results is transmitted to a sink.

摘要： Systems and methods for enhanced runtime hosting are described. In one respect, the runtime identifies any abstraction interface(s) exposed by a host application. The abstraction interface(s) correspond to respective execution environment functionality implemented by the hosting application. During execution of runtime managed code and responsive to an action or event associated with an identified one of the respective execution environment abstractions, the runtime calls a specific interface or object corresponding to a specific one of the abstraction interface(s). This allows the host application to customize/enhance its execution environment, which includes the runtime, as a function of the implemented abstraction(s).
摘要翻译：描述用于增强运行时托管的系统和方法。在一方面，运行时标识由主机应用程序公开的任何抽象接口。抽象接口对应于由主机应用实现的相应执行环境功能。在执行运行时托管代码并且响应于与相应执行环境抽象中识别的一个相关联的动作或事件时，运行时间调用与抽象接口中的特定一个对应的特定接口或对象。这允许主机应用程序根据实现的抽象来定制/增强其执行环境（包括运行时）。

摘要： A database system and method allows a user to write program code in a high-level programming language that implements a class that defines the structure of a user-defined aggregate and methods that can be invoked on instances of the user-defined aggregate. The class is then registered with the database system, which enforces a specific contract for user-defined aggregates against the class. The contract comprises the following requirements. First, the class must specify one of a plurality of different formats for persisting instances of the user-defined aggregate in a database store. Second, the class must comprise certain specified methods that can be invoked on an instance of the class. Once these requirements are satisfied, the database system enables instances of the user-defined aggregate to be created. Preferably, the database system stores metadata about the user-defined aggregate for subsequent use in creating instances of the aggregate.

摘要： Several embodiments of the present invention are directed to systems and methods for extending the UDT framework of an extended relational data store (ERDS) to include support for unordered collections (multisets) and ordered collection (lists). More specifically, several embodiments of the present invention use an UDT infrastructure, CLR generics, and a new UNNEST operator to create and utilize a special type abstraction for collections that is simultaneously a scalar and a relation. As a scalar, this collection type can be processed by all parts of the data store engine that understand scalars (including but not limited to the client stack) and, as a relation, this collection type is queriable like any other type of relation.

A particular system includes an input adapter configured to store event objects received from a source at an input queue. The system also includes a query engine configured to remove event objects from the input queue, to perform a query with respect to the removed event objects to generate result objects, and to insert result objects into an output queue. The system also includes an output adapter configured to remove result objects from the output queue and to transmit the result objects to a sink.

摘要： A system that facilitates checking the consistency of a user-defined data type in relation to a database environment. The invention can employ a user-defined type (UDT) storage format whereby values can be self-describing, including the runtime type of the value. The invention can take the type definition that is persisted in the metadata catalogs as a streaming input and generate a type-specific state machine thereafter. At every point in the checking process, the type-specific state machine can be aware of the next data type that is to be encountered in the check. Whenever an embedded UDT is encountered, the current type-specific state machine can be suspended and saved. The embedded UDT can be checked before proceeding. In this way, the complex check can be effected using memory space proportional to the number of levels in the UDT as opposed to the number of bytes in the object.

摘要： The present invention describes an efficient and fast framework for implementing table-valued functions (TVF's) in a relational database server. The framework provides desirable extensibility properties and has the ability to minimize performance degradations by integrating tightly with the optimization infrastructure in a query processor. The present invention also enables a managed execution environment (MEE) such as the Common-Language-Runtime (CLR), to efficiently and dynamically extend the logic of the database engine with user-supplied code.

摘要： Systems and methods for enhanced runtime hosting are described. In one aspect the runtime hosting interface includes a host abstraction interface. The HAI allowing the runtime to configure host execution environment parameters and/or notify the host of a runtime event. In particular, the host abstraction interface (HAI) corresponds to execution environment abstractions supported by a host application. Responsive to an action or event, the runtime invokes an identified HAI or an associated object during execution of runtime managed code.

Once these requirements are satisfied, the database system enables instances of the user-defined type to be created. A user-defined type can be used in all contexts where any other built-in type can be used. This includes defining columns of tables, declaring variables and parameters to functions and stored procedures, and evaluating expressions of the user-defined type in SQL queries and updates. Preferably, the database system stores metadata about the user-defined type for subsequent use in creating instances of the type.
