    • 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 type and methods that can be invoked on instances of the type. The class is then registered with the database system, which enforces a specific contract for user-defined types 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 type in a database store. Second, the class must be capable of returning a null value for the user-defined type. Third, the class must provide a method for converting the user-defined type to another type. 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.
    • 数据库系统和方法允许用户以实现定义用户定义类型的结构的类的高级编程语言编写程序代码,并且可以在该类型的实例上调用方法。 该类然后向数据库系统注册,该系统针对类强制执行用户定义类型的特定合同。 合同包括以下要求。 首先,类必须为数据库存储中的用户定义类型的持久化实例指定多种不同格式之一。 第二,类必须能够返回用户定义类型的空值。 第三,类必须提供一种将用户定义类型转换为另一种类型的方法。 一旦满足这些要求,数据库系统就可以创建用户定义类型的实例。 可以在可以使用任何其他内置类型的所有上下文中使用用户定义的类型。 这包括定义表的列,将变量和参数声明为函数和存储过程,以及评估SQL查询和更新中用户定义类型的表达式。 优选地,数据库系统存储关于用户定义类型的元数据,以便随后用于创建该类型的实例。

    • Embodiments of the present disclosure set forth a method for retrieving information from a semantic database having a plurality of semantic data. The method includes selecting a hub that is resolved with a number of semantic data based on a resolution rule, when the number of the semantic data is greater than a threshold in an offline environment; calculating a semantic data set that is associated with the hub based on a searching approach and the resolution rule in the offline environment; indexing the semantic data set in the offline environment; modifying the semantic database to include the semantic data set in the offline environment; and retrieving information from the semantic data set in an online environment.
    • 本公开的实施例提出了一种从具有多个语义数据的语义数据库中检索信息的方法。 所述方法包括当离线环境中所述语义数据的数量大于阈值时,基于解决规则选择用多个语义数据解析的集线器; 基于搜索方法和离线环境中的分辨率规则计算与集线器相关联的语义数据集; 索引离线环境中的语义数据集; 修改语义数据库以在离线环境中包括语义数据集; 以及从在线环境中的语义数据集中检索信息。
