Re: 5 instances = too much ???

I would like to add a little but very obvious thingy 5 Ask whether they use primary or foreign key constraints, and if not by what other means they validate and enforce relational integrity. I asked this question to three different technical people of Broadvision (vendor of e-commerce sw) and in all three cases they avoided to answer the question, saying something they don't need it, because data is never really deleted, only flagged as deleted. Now you guess what kind of RI mechanism they were using... Right: None at all
If that's the situation and you already have decided to buy such crapware, make sure you hire a good lawyer.
