As I indicated in prior posts, "XDb1 beta v4.4.7" did have an error passing the parameters correctly to the report generator (because the root doesn't have any thing higher than it). But "XDb1 beta v4.4.7" did have the ability to generate a report for the class hierarchy and was not added at a later time. To verify this, open Ex076.xdb and type the following statement into the NLI:

query is thing.

This (luckily) satisfies the report generator to which query looks "higher" than thing. Right-clicking the root node labeled 'thing', and selecting 'Generate Anc Report" produces the following 317 KB Report:

As one can see, not only is "XDb1 beta v4.4.7" capable of generating the class hierarchy report, the db has an entry for each symbol. Each symbol was entered by XDb1 into the db when it was first created. All data (ie 'john' or 'god') enter by the user subsequently are normalized to the one and only symbols in the db.

Also note that the "XDb1 beta v4.4.7" that was available at the website was compiled in debug mode. The above report is generated by the same version except it was compiled in release mode, thus your "time elapsed" will be different. Received on Sun Jun 06 2004 - 22:34:00 CEST
