sql server - SSAS 2012 - Dimension Modeling -


i working structure results lot of single attribute dimensions require no hierarchy. examples:

  • status(status name)
  • type(type name)

i following warning when compiling project:

"avoid having multiple dimensions containing single attribute. consider unifying them if possible."

a large number of single attribute dimensions workable our users, causes lot of clutter in excel pivot table. dimensions listed along single attribute redundant.

single attribute dimension

i unify them warning suggests have single dimension called 'attributes' contains status/type/etc, unsure best way so. doesn't make conceptual sense me parent/child dimension.

any suggestions?

i agree worthwhile change. construct view brings required attributes. available on fact/measure group table/view, can use same source object (in dsv) construct dimension.

the tricky part may dimension key. flexible key fact surrogate key eg unique value per fact row - in future can add other fact-based attributes without affecting key. not scale indefinitely - ok 1m rows @ least.

beyond scale, concatenate attributes form dimension key , deliver them new dimension table. in etl layer. identical concatenation logic must used both dimension , fact.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
