Abstract: An apparatus and computer program product determine a target data type in an environment having a plurality of levels. The plurality of levels comprise a source level, zero or more intermediate levels, and a target level. The zero or more intermediate levels are between the source level and the target level. A target data type representing a transformation of a data type of an associated datum as the datum passes from the source level through the zero or more intermediate levels to the target level is generated. The target data type comprises a sequence of nested transformation functions having an innermost transformation function and an outermost transformation function.

Abstract: An apparatus and article of manufacture for determining a target data type in an environment having a plurality of levels are provided. Zero or more intermediate levels are between the source level and the target level. A target data type representing the transformation of a data type of an associated datum as the datum passes from the source level through the zero or more intermediate levels to the target level is generated. In another aspect of the invention, the datum is assigned to the target level in accordance with the target data type. In yet another aspect of the invention, the target data type is passed with the associated datum, via the zero or more intermediate levels to the target level.

Abstract: Method, system, and program product for searching unstructured data. The unstructured data, as text data or image data, is searched by first searching the unstructured data through an extended search broker. The extended search broker has intermediary components between a search requestor and a search agent for unstructured data searching. The search agent returns the search results to the broker for aggregation. The broker aggregates the search results and returns the search results to a wrapper. The wrapper then takes result attributes from the aggregated search results and makes the attributes available, e.g., as one or more columns in a nickname table. This nickname table is searchable by a relational database using a structured query language.
