[erlang-questions] Re: Some tips on Mnesia

[Rapsey]

About that key value approach. My solution is a bit different. Let's say I
have a database of nodes and store a list of IP addresses to them. I save
them like so:
{node,{address,NodeName}}, {IP,Port}

This way I can query for that exact information mnesia:(dirty_)read, or I
can get a list of all node addresses with mnesia:select -
{node,{address,'_'}}, or get a list of all node information with {node,'_'},
or get all info about a node {node,{'_',NodeName}}.
