    30 On the contrary to !MapReduce, writing code in !PigLatin is as straight forward as it can get. There's no need to wory about ''how'' things are done, one just has to specify ''what'' needs to be done.
     30On the contrary to !MapReduce, writing code in !PigLatin is as straight forward as it can get. There's no need to wory about ''how'' things are done, one just has to specify ''what'' needs to be done. Describing this seems more natural in PigLatin, for example the b. program is just computing an average. As a general idea, one has to group what one would have used in MapReduce as a key and a big advantage is that a join is much easier to do.
