    • An application program interface (API) for a data platform. The API includes a generic data access component that exposes at least one of stores, sessions, transactions, and query services of the data platform, which data platform is associated with a data store. A data classes component of the API provides canonical, application-independent classes that expose types and relationships of a data model of the data platform. The API includes a domain data classes component of application-specific and framework-specific classes that expose domain-specific properties and behaviors of the data platform. The data platform can be a common data platform that interfaces to the data store to provide data services accessible by a plurality of disparate application frameworks, which data services allow a corresponding application of the different frameworks to access the data store.
    • 用于数据平台的应用程序接口(API)。 API包括通用数据访问组件,其暴露数据平台的至少一个存储,会话,事务和查询服务,该数据平台与数据存储相关联。 API的数据类组件提供了规范的,独立于应用程序的类,用于暴露数据平台数据模型的类型和关系。 该API包括专门针对特定于应用程序和特定于框架的类的域数据类组件,以暴露数据平台的特定于域的属性和行为。 数据平台可以是与数据存储器接口以提供可由多个不同应用框架访问的数据服务的通用数据平台,该数据服务允许不同框架的相应应用访问数据存储。

    • A query processor's capabilities may be employed to identify a range rows resulting from a user query to be returned. A server cursor may be declared, opened, fetched from and closed in a single batched request in order to avoid keeping state on a database server between requests. A single block fetch may be used within the batch to retrieve a requisite number of rows from a specified ordinal position. Where server cursors are not available, an intermediate table may be used to hold a subset of the rows resulting from the user query, and row numbers may be added to facilitate selecting the range of rows from that intermediate table. Intelligence within a query processor may be leveraged to support identifying the range of rows to be returned without maintaining state between client requests.
    • 可以使用查询处理器的能力来识别由要返回的用户查询产生的范围行。 可以在单个批量请求中声明,打开,取出并关闭服务器游标,以避免在请求之间保持数据库服务器上的状态。 可以在批处理中使用单个块提取来从指定的顺序位置检索必要数量的行。 在服务器游标不可用的地方,可以使用中间表来存储由用户查询产生的行的子集,并且可以添加行号以便于从该中间表选择行的范围。 可以利用查询处理器内的智能来支持在不维护客户机请求之间的状态的情况下识别要返回的行的范围。

    • The present invention relates to systems and methods for employing a trigger based mechanism to detect changes in a database table, providing a notification when the database table changes and registering to receive the notification. The systems and methods employ a listeners table to store information associated with registered database tables. Alter a database table changes, a trigger mechanism associated with the database change facilitates a search of the listeners table for a parameter associated with the changed database table. If the changed database table is registered, the information from the listeners table is provided to a delivery service which transmits a message indicating the registered database table changed. After receiving the message, a notification runtime service can route a notification to a client(s) registered to receive the notification. The foregoing mitigates performing time intensive queries and utilizing inconsistent query results.
    • 本发明涉及采用基于触发的机制来检测数据库表中的变化的系统和方法,当数据库表改变并注册以接收通知时提供通知。 系统和方法使用侦听器表来存储与注册的数据库表相关联的信息。 更改数据库表更改,与数据库更改相关的触发机制更改便于对监听器表的搜索与更改的数据库表相关联的参数。 如果更改的数据库表被注册,则将来自侦听器表的信息提供给传送指示已注册数据库表改变的消息的传送服务。 收到消息后,通知运行时服务可以将通知发送给已注册接收通知的客户端。 前述情况减轻了执行时间密集型查询并利用不一致的查询结果。

    • A system and method facilitating a unified framework for accessing structured and unstructured data is provided. The invention includes a source document having data that is parsed into a data document component providing a hierarchical representation of data associated with the source document and a data set component providing a relational representation of at least a portion of the data associated with the source document. The invention further provides for a schema defining a structure of the relational representation to be associated with the source document and/or inferred by the data set component. Data stored in the data document component and the data set component are synchronized, thus a change made to data stored in the data set component is reflected in data stored in the data document component. Further, a change made to data stored in the data document component is reflected in data stored in the data set component if utilized according to the schema. The invention further provides for a service to access the hierarchical representation of data associated with the source document and/or a designer to access the relational representation of data associated with the source document.
    • 提供了一种便于统一框架访问结构化和非结构化数据的系统和方法。 本发明包括具有被解析成数据文档组件的数据的源文档,该数据文档组件提供与源文档相关联的数据的分层表示,以及提供与源文档相关联的数据的至少一部分的关系表示的数据集组件。 本发明还提供了定义与源文档相关联和/或由数据集组件推断的关系表示的结构的模式。 存储在数据文档组件和数据集组件中的数据被同步,因此对存储在数据集组件中的数据所做的改变反映在数据文档组件中存储的数据中。 此外,如果根据模式使用,对存储在数据文档组件中的数据的变化反映在存储在数据集组件中的数据中。 本发明还提供一种服务,用于访问与源文档相关联的数据的分层表示和/或设计者以访问与源文档相关联的数据的关系表示。
