>Hi Alejandro,
>I wouldn't use a DBC. You should design the locking such that related tables are sure to be updated. I would also feel free to break some normalization rules along the way. Think about the way VFP does the PJX or VCX files. The Project file has one HomeDir field--only used by one record. That's wrong--but oh so right for the task. We like having the project in a single (or two with the PJT file) file. The VCX/SCX files have a comment record, dataenvironment record and so on. If VFP normalized these files, each ClassLib would be sourced in a variety of files--but I'm glad they don't.

I appreciate your suggestion about the DBC and will probably do that.

About bending normalization to reduce the number of tables, I got it down to 3 dbf's and 3 cdx's. That is appropriate because this is a simplified freebie meant to lead to full product sales.

Thanks fro your input.

Alex
