摘要： Methods, systems and computer program products for interactive generation of integrated schemas. Exemplary embodiments include a method for schema integration, the method including recasting a first source schema into a first graph of concepts with HasA relationships, recasting a second source schema into a second graph of concepts with HasA relationships, identifying matching concepts in the first graph and the second graph based on correspondences between attributes of the concepts of the first and second graphs, producing an integrated schema, based on a fixed specification of matching concepts to merge, and generating a mapping from the first source schema to the integrated schema and from the second source schema to the integrated schema.

摘要： A method for generating a schema mapping. A provided mapping M12 relates schema S1 to schema S2. A provided mapping M23 relates schema S2 to schema S3. A mapping M13 is generated from schema S1 to schema S3 as a composition of mappings M12 and M23. Mappings M12, M23, and M13 are each expressed in terms of at least one second-order nested tuple-generating dependency (SO nested tgd). Mapping M13 does not expressly recite any element of schema S2. At least one schema of the schemas S1 and S2 may comprise at least one complex type expression nested inside another complex type expression. Mapping M13 may define the composition of the mappings M12 and M23 with respect to a relationship semantics or a transformation semantics.

摘要： A multi-structural query system performs a high-level multi-dimensional query on a multi-structural database. The query system enables a user to navigate a search by adding restrictions incrementally. The query system uses a schema to discover structure in a multi-structural database. The query system leaves a choice of nodes to return in response to a query as a constrained set of choices available to the algorithm. The query system further casts the selection of a set of nodes as an optimization. The query system uses pairwise-disjoint collections to capture a concise set of highlights of a data set within the allowed schema. The query system further comprises efficient algorithms that yield approximately optimal solutions for several classes of objective functions.
