    • A method and apparatus for defining and processing aggregate data is disclosed. Using database abstraction techniques, a set of logical fields may be used to compose queries of a set of underlying physical data sources. In one embodiment, a logical field may represent an aggregate data value calculated from the elements appearing in a column of a relational table in an underlying physical data source. The elements may be divided into to subsets to calculate multiple aggregate values. An abstract derived entity is a data object present in a database abstraction model that may be accessed as though it were a relational table contained in an underlying physical data source. In one embodiment, columns of the table defined by the abstract derived entity may be populated with aggregate data values joined to other data as specified by a composition rule included in the definition of the abstract derived entity.
    • 公开了一种用于定义和处理聚合数据的方法和装置。 使用数据库抽象技术,可以使用一组逻辑字段来构成一组底层物理数据源的查询。 在一个实施例中,逻辑字段可以表示从出现在底层物理数据源中的关系表的列中的元素计算的聚合数据值。 元素可以分为子集,以计算多个聚合值。 抽象派生实体是存在于数据库抽象模型中的数据对象,可以被访问,就像它是包含在底层物理数据源中的关系表一样。 在一个实施例中,由抽象派生实体定义的表的列可以填充与由包括在抽象派生实体的定义中的组合规则指定的其他数据连接的聚合数据值。

    • The present invention generally is directed to a method, system and article of manufacture for controlling the access to data granted to a requesting entity based upon data accessed by the entity in the past. Additionally, embodiments of the present invention allow for access control independent from the particular manner in which the data is physically represented. Generally, abstraction layers are provided to represent various data sources available for use by an application and to compose queries used by the application to access and/or update information contained in these data sources. A runtime component is responsible for resolving an abstract query into concrete data access requests to one or more data repositories using information contained in a data repository abstraction component (one of the abstraction layers). Typically, data is organized into a series of domains. Within each domain, data is associated with an account. User activity is monitored, and when data associated with one account is accessed, a user may subsequently be prohibited from accessing data from a related account within the same domain.
    • 本发明一般涉及一种用于根据过去由实体访问的数据来控制对授权实体授予的数据的访问的方法,系统和制品。 另外,本发明的实施例允许独立于物理表示数据的特定方式的访问控制。 通常,抽象层被提供以表示可供应用使用的各种数据源,并且构成应用程序使用的查询访问和/或更新这些数据源中包含的信息。 运行时组件负责使用数据存储库抽象组件(抽象层之一)中包含的信息将抽象查询解析为对一个或多个数据存储库的具体数据访问请求。 通常,数据被组织成一系列域。 在每个域内,数据与一个帐户相关联。 监视用户活动,并且当访问与一个帐户相关联的数据时,随后可以禁止用户从同一域内的相关帐户访问数据。
