I will say, I think the product's technical underpinning is not ideal. Instead of just using SQL, they have a proprietary language built in which has similarities to SQL but is much less easy to read and use. For instance a lot is stored in Metadata tables that are many clicks away from the report they're referencing. Also, there are a few cryptic keywords and things specific to WebFocus, which is obviously not that widely used and doesn't have many S.O. posts about it. So you're left staring at some various mysterious keywords or specific-syntax and thinking, do I learn anything more about this than what I need to, since this product is probably not going to last and will end up in the dust-bin like many other proprietary products. And it's just not a very employable skill like SQL.
Overall, I don't like WebFocus, I think Tableau must be a couple notches better. But hey, my org is under-staffed and we don't have the manpower to change systems, so we're stuck with this.
