| Popis: |
The hierarchical organisation of the Read Thesaurus, a fundamental feature that supports aggregation, summarisation and data entry, has previously been represented within the code itself. As Read Version 3 uses a separate table which supports multiple parents, hierarchy-based analysis becomes more complex and requires optimisation to achieve acceptable response times. Depth-first numbering of the Version 3 hierarchy allows the descendants of any node to be represented by a series of ranges and to be analysed at speeds similar to the simpler trees of earlier versions. |
