The present invention generally is directed to a system, method and article of manufacture for accessing data independent of the particular manner in which the data is physically represented. In one embodiment, a data repository abstraction layer provides a logical view of the 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 translation of an abstract query into a form that can be used against a particular physical data representation.

Application portability and extensibility through database schema and query abstraction

The present invention generally provides methods, systems and articles of manufacture for programmatically providing a user interface for creating queries. In one embodiment, graphical user interface content which defines a graphical user interface is provided. The graphical user interface comprises (i) a region for displaying conditions of a query; and (ii) a first graphical element for initiating a process of combining two or more conditions of the query together with logic values to form a complex condition. In another embodiment, the graphical user interface further comprises a second graphical element for initiating a process of separating two or more conditions of a complex condition.
