Re: [gentoo-portage-dev] Few things, which imho would make portage better

I didnt think of case Item1, Item2, Item3.

I thought of cases, for example, where i use Id field as TableName and
IdInThatTable, where TableName shows, which table this IdInThatTable
points and so on. I dont use, too, Item1/2/3 :) I just use tables
sometimes in a more generalized form, where it's hard to say from
table name or fields, what it is supposed to contain, as it contains
different things in different cases -- therefore allowing me to make
more functionality to general datastructures rather than writing
specific tables with specific functions. Anyway, this is an example --
i just think that normalizing makes it so that there is 1 way to do
things, but i like to rethink any specific case (and in some cases,
normalized table just appears best to me, but not because it's
normalized). Nothing more. Anyway, i think that this is not a topic to
discuss in this list :) I think that db-app otimizations was best
argument ever possible on side of normalization -- others are those,
which will appear to me, too, but i havent much thought about which
db's are optimized to which structures -- and this seems so that as
normalization is in, any engines probably really are optimized for
that.
