Successes in these studies included women with: 1  two totally blocked fallopian tubes, 2  one tube removed and the other blocked (decreasing the chance for success), 3  hydrosalpinx (tube blocked and filled with fluid), and.  mid-tube and distal blockage (challenging areas to treat surgically).
Data Rationalization is a powerful means to unlock and leverage semantics hidden in models, and to be able to find, identify, and leverage the data we need. Tying a formal ontology (e.g. stored in OWL) to model objects can help bridge the semantic divide between unstructured and structured data.

Traditionally, three phases are identified in database design: conceptual, logical and physical design.
