A database is provided in which conclusion sets (20 22, 24, 26, 28 and 30) , are divided into a hierarchical series of levels (level 1 level 2, level 3). , Data is added to a conclusion set at the first level (level 1) until such time as that conclusion set is full. Data is then migrated from the conclusion set (20) to its subordinate conclusion sets (24 26) therefore reducing the amount , of disc access required to add data to the database since multiple entries are migrated in relatively few disc access operations.

Why it's free to use
- Filed February 19, 2002 and granted November 1, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 19, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
