    • The present invention provides systems and articles of manufacture that enhance the capability of a database abstraction model and query application constructed for an underlying physical database. Typically, the query application is used to compose and execute an abstract query. Once an initial query result is presented to a user, a user may select to execute a model entity operation by interacting with a query interface of the query application. A model entity operation allows the user to retrieve additional information from the underlying database, based on information included in the initial query result, without having to create a new query or having to correlate the results of multiple queries.
    • 本发明提供了增强针对底层物理数据库构建的数据库抽象模型和查询应用的能力的系统和制品。 通常,查询应用程序用于撰写和执行抽象查询。 一旦向用户呈现初始查询结果,用户可以选择通过与查询应用的查询界面交互来执行模型实体操作。 模型实体操作允许用户基于初始查询结果中包含的信息从底层数据库检索附加信息,而不必创建新查询或必须将多个查询的结果相关联。

    • A method, system and article of manufacture for managing access to a data abstraction model abstractly describing physical data and, more particularly, for creating a logical security model for a data abstraction model abstractly describing data in a database. One embodiment provides a computer-implemented method for creating a logical security model based on a physical security model defining user access rights to physical data. The method comprises, for each of the user access rights defined by the physical security model, creating a logical access right definition for a logical model. The logical model comprises a plurality of logical field definitions each comprising a field name and access information for accessing a field of the physical data. The logical access right definitions are applied to the logical model so that the logical model reflects the user access rights to the physical data.
    • 用于管理对抽象地描述物理数据的数据抽象模型的访问的方法,系统和制品,更具体地,用于为抽象地描述数据库中的数据的数据抽象模型创建逻辑安全模型。 一个实施例提供了一种用于基于定义用户对物理数据的访问权限的物理安全模型来创建逻辑安全模型的计算机实现的方法。 对于由物理安全模型定义的每个用户访问权限,该方法包括为逻辑模型创建逻辑访问权限定义。 逻辑模型包括多个逻辑字段定义,每个逻辑字段定义包括用于访问物理数据的字段的字段名称和访问信息。 逻辑访问权限定义被应用于逻辑模型,使得逻辑模型反映用户对物理数据的访问权限。

    • Embodiments of the invention provide methods, systems, and articles of manufacture for transforming a physical query (e.g., written in SQL) into an abstract query than can be run against an abstract database described by a database abstraction model. In one embodiment, the transformation occurs as a multiple step process: first, transformation of the physical query into an intermediate representation, such as an abstract query plan, and second, transformation of the intermediate representation into an abstract query. There are thousands upon thousands of existing physical (e.g., SQL) queries. Rather than just abandon these existing queries in favor of an abstract database, embodiments of the present invention provide for reverse query processing, that is, for creating an abstract query of the abstract database from a physical query (e.g., an SQL query) of the physical database underlying the abstraction.
    • 本发明的实施例提供用于将物理查询(例如,以SQL编写)转换成抽象查询的方法,系统和制品,而不是可以针对由数据库抽象模型描述的抽象数据库运行。 在一个实施例中,转换以多步骤过程发生:首先,将物理查询转换为诸如抽象查询计划的中间表示,以及第二,将中间表示转换为抽象查询。 有成千上万的现有物理(例如SQL)查询。 而不是简单地放弃这些现有的查询以支持抽象数据库,本发明的实施例提供反向查询处理,即,用于从所述抽象数据库的物理查询(例如,SQL查询)创建抽象数据库的抽象查询 基础抽象的物理数据库。

    • Embodiments of the invention provide methods, systems, and articles of manufacture improving the process of query composition, query processing, and presenting query results to users of an abstract database. Embodiments of the present invention organize and view data using abstract records. Specifically, users compose a query according to the logical relationships present in the data. Rather than evaluate conditions against a set of rows from a relational table, conditions included in abstract query are evaluated against instances of an abstract record. Instances that satisfy the conditions specified by an abstract query are returned as query results. In a specific case abstract records are used to evaluate a “never exists conditions, that determine the absence of data in an abstract records that satisfy a particular condition.
    • 本发明的实施例提供方法,系统和制品,改进查询组合,查询处理和向抽象数据库的用户呈现查询结果的过程。 本发明的实施例使用抽象记录来组织和查看数据。 具体来说,用户根据数据中存在的逻辑关系构成查询。 不是根据关系表中的一组行来评估条件,而是根据抽象记录的实例来评估抽象查询中包含的条件。 满足抽象查询指定条件的实例作为查询结果返回。 在具体情况下,抽象记录用于评估“从不存在的条件,确定在满足特定条件的抽象记录中不存在数据。
