documentation for hrr in the haskelldocumentation repository

[cdepillabout]

It looks like FPcomplete and Michael Snoyman recently started the Commercial Haskell group. They are putting together a repository of documentation for teaching intermediate-level haskell. Here is the email thread introducing the documentation repository.

Looking through the outline, it looks like they have a section for databases.

I think it would be great if there were an article about HRR. Especially since it would be the first database article.

The last email in the email thread linked above says "Like I say in the README, commit access to this repo should be given out freely, so if someone wants to get involved, just go for it, no permission needed." So it sounds like an article on HRR would probably be accepted.

After the article was completed, it could probably be submitted to reddit as well.

I would be willing to do translations from Japanese to English. Or even just check over an article written in English.

Now I'm discussing this with Michael in private.

Okay, sounds good! I'll be interested to hear about it!

What is haskell-relational-record's relation to haskelldb?

[kazu-yamamoto]

HRR is a next generation of HaskellDB. The main author of HRR, Hibino, used to use HaskellDB. Through this experience, he found some shortcomings of HaskellDB:

• No support for outer join
• No support for group by
• No support for place holder
• Non-standard records are used
• Conflict of column names
• Need to prepare many boilerplate

Correct me if I'm wrong.

HRR was designed to solve all problems above.

@cdepillabout Since we have no human power to write another tutorial about HRR, I just added a link to HRR homepage.

@kazu-yamamoto Okay sounds good!

@kazu-yamamoto Thanks, that clarifies.
