Abstract: A tabular operation provider is provided for processing a data agnostic business intelligence query with relational operations, herein called a relational query against a multidimensional datasource. The tabular operation provider comprises a query interceptor, a query decomposer and a query replacer. The query interceptor detects and intercepts a relational query that is issued against one or more multidimensional data sources. The query decomposer decomposes expressions of the relational query into one multidimensional expression and one or more relational expressions. The query replacer replaces the relational query with a stack of operations expressed by the decomposed multidimensional expressions and/or the relational expressions.

Abstract: 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.
