Hi Rob -- It is the rare table, indeed, that is created with a sql CREATE TABLE statement in a U2 database. U2 has SQL as a second language. It is not really an RDBMS, but uses a data model very similar to the one used by XML (a tree or di-graph structure).
With the CREATE-FILE command a file gets created and then when a dictionary is populated, it is descriptive of the data (so not quite the same as an RDBMS that way) and can include sub-fields. The database comes pre-loaded with functions on multi-values and multi-valued sub-values and users write similar functions to lower levels if needed. Let me know if that doesn't quite answer the question. Thanks. --dawn Dawn M.

Anybody want to answer his question? I could do it but I'm kind of busy right now.

You can see the entries at: http://www.rpbourret.com/xml/ProdsXMLEnabled.htm#unidata http://www.rpbourret.com/xml/ProdsXMLEnabled.htm#universe Comments / corrections welcome. (One question I had was whether UniVerse supports multi-subvalued columns as well as multi-valued columns. There are a number of references to subvalues in the documents, but the UniVerse CREATE TABLE command does not seem to support them...)
