A method, system and article of manufacture for managing access to queries and, more particularly, for managing access by multiple users to persistently stored queries. One embodiment provides a method of managing access by multiple users to a predefined query against data in a database. The method comprises associating one or more access rights with at least some portion of the predefined query. When a request to access the predefined query by a first user is received, access to the predefined query by the first user is limited on the basis of the access rights.

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.

A system, method and article of manufacture for managing query results and, more particularly, for sorting data records contained in a query result obtained in response to execution of a query against a database. In one embodiment, the data records in the query result are sorted on the basis of related information which is retrieved from a corresponding data source. In another embodiment, the sorting is performed on the basis of a value variance which is determined for each of the data records in the query result. In still another embodiment, the sorting is performed on the basis of a requested value range coverage. In yet another embodiment, the sorting is performed on the basis of suitability scores which are determined with respect to analysis routines which are configured for processing the query result.

A method, system and article of manufacture for processing rule sets and, more particularly, for processing abstract rule sets. One embodiment provides a computer-implemented method of managing execution of an analysis routine on input data. The method comprises receiving input and receiving user-selection of an analysis routine for processing the received input. The analysis routine is defined by at least one abstract rule set having one or more abstract rules each having a conditional statement and a consequential statement. The method further comprises executing the analysis routine on the received input, comprising (i) identifying all required inputs for each abstract rule of the analysis routine, (ii) determining whether the received input includes data for all required inputs, and (iii) if the received input does not include data for one or more of the required inputs, retrieving suitable data for the one or more of the required inputs from the database.

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.

One embodiment of the invention provides method for processing a database query that includes an episode-based condition. The method includes determining the time periods associated with one or more duration episodes by analyzing a set of data reflecting values for the episode-based condition captured at various points in time. An episode definition may indicate the substantive data value associated with a duration based event, and the data values used to determine a beginning and ending date/time associated with each episode. Database queries that include the episode-based condition may be composed by specifying a desired value for the episode-based condition used in selecting query results.
