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.
Benefits of Normalization. Normalizing a logical database design involves using formal methods to separate the data into multiple, related tables. Several narrow tables with fewer columns is characteristic of a normalized database. A few wide tables with more columns is characteristic of an non-normalized database. For a description of the normalization rules and an example of applying them a database design, see the Introduction to Database Design Video. Reasonable normalization frequently improves performance.
