Abstract: Systems and methods that enable consistent navigation (for a database and memory environment) in object relational mapping. This typically ensures fidelity of object graph via restrictions on collections of persistent objects (e.g., entity sets, entity refs . . . ). Moreover, a tracking component can detect changes as they occur, and only a copy of the objects that have changed can be created, to optimize operation.

Abstract translation: 在对象关系映射中实现一致导航（用于数据库和内存环境）的系统和方法。 这通常通过对持久对象的集合（例如，实体集，实体参考）的限制来确保对象图的保真度。 此外，跟踪组件可以检测到它们发生的变化，并且可以仅创建已经改变的对象的副本来优化操作。

Abstract: A system for converting a query from a representation in a first computing language to an equivalent query in a representation in a second computing language that is different from the first computing language, comprises a query module that accepts a query in an object-oriented representation for translation to an equivalent query in a target query language. The system also includes a translation module that uses the object-oriented representation of the query to create a first version of the query in an idealized version of a target query language and uses the first version of the query to create a second version of the query in an implemented version of the target query language. Methods of using the system are also provided.

Abstract: A general-purpose programming language having language extensions for strongly typed, compile-time checked query and set operations that can be applied to arbitrary data structures, be they object-relational (O-R) mappings or just regular objects. As is appropriate for a general purpose programming language, the extensions do not mandate a particular object-relational layer; rather, they are introduced as abstractions that can be implemented in multiple environments. Accordingly, there is provided a system that facilitates data querying in accordance with an innovative aspect. The system include a program component that provides embedded query and set operations in a programming language, and an application component that facilitates application of the query and set operations over a data structure of data. The data can be any kind of data such as that found in a database, a document (e.g., XML), and data sources in a programming language (e.g., C#), for example.

Abstract translation: 具有用于强类型，编译时检查查询和可应用于任意数据结构的集合操作的语言扩展的通用编程语言，无论是对象关系（O-R）映射还是只是常规对象。 适用于通用编程语言，扩展不要求特定的对象关系层; 相反，它们被引入可以在多个环境中实现的抽象。 因此，提供了一种根据创新方面促进数据查询的系统。 该系统包括以编程语言提供嵌入式查询和集合操作的程序组件，以及促进查询应用并且对数据的数据结构设置操作的应用程序组件。 数据可以是例如在数据库，文档（例如，XML）中找到的任何类型的数据，以及编程语言（例如，C＃）中的数据源。

Abstract: The subject invention relates to systems and methods that provide null capabilities within the context of programming languages. In one aspect, a system is provided that facilitates null-support in various programming languages. The system includes one or more types associated with at least one programming language. A type modifier is provided to signal that the type is nullable. The type modifier enables a multi-element structure to be automatically created in association with the type wherein, the multi-element structure includes the type and a Boolean element indicating whether or not the variable is null.
