Multivalued Fields a Good Idea?

I have recently been introduced to the new Access 2007 feature which is multivalued fields. My initial impression is that it is a bad idea to make use of multiple values in a single field. Traditionally if you wanted to allow for a record to have several values for a field you would create another two tables and link them with foreign ...

Pick and RDF/SPARQL

Anyone have any interest in intergrating RDF and/or SPARQL with a PICK database? Has anyone tried this yet? I have some thoughts about what to try. One idea is to figure out how to create a file with a dictionary that defines some correlatives that allow data to be pulled from the file as RDF, as one or many of n-triple, turtle, n3 or XM...

UniVerse learning materials

I've recently come in contact with a proprietary descendant of UniVerse. Does anyone know where I can get a good tutorial or brush up on the syntactic quirks of its more popular parent?

Multi-valued Database (UniVerse) -- SM (MV) vs SM (VS) and ASSOC()

I have a question taken from pg 16 of IBM's Nested Relational Database White Paper, I'm confused why in the below CREATE command they use MV/MS/MS rather than MV/MV/MS, when both ORDER_#, and PART_# are one-to-many relationships.. I don't understand what value, vs sub-value means in non-1nf database design. I'd also like to know to know ...

UniVerse RetreiVe how do I query a file for all of its column's values?

Kind of a follow up to my self-answered question about finding the column names. In UniVerse you can't query a file for all of its columns unless the @ phrase in your file's dictionary is set to all of the tables columns. If it isn't how do you query a table for all of its column's values? So I can get the total column listing (column ...

U2 Basic Developer Toolkit

Does anyone here run the Basic Developer Toolkit with UniData 7.1? Even though the IDE was released with UniData 7.2, I was given the impression that it works fine with 7.1. However, when opening up "Database Files" in an account, every single DIR type file gives a loading error dialog and doesn't register any records in them. Are chan...
