摘要： Methods, systems, and articles of manufacture for accessing data stored in multiple data sources. Such methods employ an automated software agent to maintain a collection of data sources available for querying. The data sources may all reside within a single local network or may be distributed throughout multiple locations. Generally, the automated software agent searches a given domain for additional data sources according to a defined set of selection criteria. After discovering an additional data source, the automated software agent configures a query application to reflect the availability the additional data source. Further, the automated software agent may periodically evaluate the collection of data sources against the selection criteria and remove those that are either no longer available or no longer satisfy the selection criteria.

摘要： Methods, systems, and articles of manufacture for enhancing abstract queries by utilizing conditional modifiers with logical fields are provided. Conditional modifiers allow for the referencing of multiple physical fields via a single logical field. Further, conditional modifiers facilitate the ability to specify, on an instance by instance basis, which physical field or combination of physical fields a particular logical field should reference.

摘要： Systems and articles of manufacture for managing metadata associated with a data abstraction model abstractly describing data in a database. One embodiment provides a technique for managing metadata describing objects of a data abstraction model with logical fields that define abstract views of physical data in a database. Managing metadata includes traversing a logical tree structure representing the data abstraction model. The logical tree structure has a plurality of nodes, each representing a logical field or a category of logical fields of the data abstraction model. Managing metadata also includes identifying metadata describing logical fields or categories represented by the plurality of nodes. The identified metadata is stored in a queryable database. A user is allowed to query the database to identify objects in the data abstraction model that may be used to construct an abstract query.

摘要： 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.

摘要： The present invention is generally directed to a system, method and article of manufacture for accessing data represented abstractly through an abstraction model. In one embodiment, a data repository abstraction layer provides a logical view of an underlying data repository that is independent of the particular manner of data representation. A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs conversion of an abstract query (i.e., a request for results or a request to modify data) into a form that can be used against a particular physical data representation. Abstract and/or physical queries are transformed according to model entities which define a relationship between logical fields of the data repository abstraction layer.

摘要： 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.
