RelDB: The Desktop Relational Database Management System
- sbuttgereit 10y agoI'm not sure that I really get which audience that RelDB is trying to reach. Their website is not very helpful in this regard either. I guess if you're wanting a way to teach basics of the relational model with a language more suited to demonstrating principle, mmm... okay (I only glanced at the grammar bit and quickly walked away). But outside of some relatively theoretical educational use cases, this doesn't seem to solve any problem that isn't being adequately solved, and likely more practically solved, by other, more established, solutions. Certainly the website linked didn't give me any reason to care.

- jitl 10y agoI have a ton of unanswered questions about this software, and the website is of no help. - is this a GUI application? If so, what does it look like? - can I manage any relational database, or only DBs internal to this application? - what does this offer over SQlite3? - can I leverage Rel in an application, or is it only a learning tool? I don't understand why this showed up on HN's first page.
- iso-8859-1 10y agoYou cannot manage any relation database with this, it is a database itself. You can't query MySQL using the psql tool either. The advantage of Tutorial D is that it is closer to relational algebra than SQL is. Which means that it probably doesn't have any null or three-valued logic. https://en.wikipedia.org/wiki/D_(data_language_specification)#Tutorial_D https://en.wikipedia.org/wiki/D_(data_language_specification...
