If you're ready to start that survey re Relational Databases,
here's a first submission.
n-ary relations are built-in types in the mKR language (http://mKRmKE.org/)
Relation tuples are represented as comma-separated values.
The unique thing about mKR relations is that they have a built-in
context-dependent
meaning. The meaning is a list of mKR propositions, with UNIX-shell-style
variable substitution. Other attributes of relations may be used to specify
automatic declarations, mode (in core or database), etc.
Here's a simple example of a relation.
address book is relation with
format = [person:1, email:2, phone:3],
meaning = { $1 has email = $2, phone = $3; };
begin relation address book;
John Doe, jdoe@PioneerCA.com, 209-555-1212;
Jane Doe, jdoe@unitednations.org, 212-555-1212;
end relation address book;
Here are some example queries.
address book isc* ?; # all tuples
? has email = ?; # all email addresses
John Doe has ?; # email & phone
