approches to transmit parametres from conf.document

usually every application has at least one configuration document which contains some information about our application and of course you should to use these data in your application.

1. @DbLookUp and @DbColumn every time
first way is to create a view where you can find this document (@DBLookUp or @DbColumn)and receive needed data each time when you want, but it's very slowly way and stupid, because there are a lot of dblookup will be.
2. transmit Id of config doc
there is one another way which I prefer to use is to transmit the id of conifg documents (using @dblookup or other ways) and then each time when you need some data, you can use @getdocfield(id; fldName)
3. collect all data in 1 field in profile and then use this field
Another one good approach is to save all data in configuration document in one field, for example [fldName1]fldValue1:[fldName2]fldValue2:[fldName3]fldValue3 and so on, after that you can load this field using just 1 @dblookup and then parse it and receive this data. This method I used very often too, but now I switch to method #2.

ok, i know that we can you real profile documents, but i don't like to do it, and I'm not able to tell you why is it so :)
but any suggestion and new idea will be appreciate !
