difference between multiprovider and infoset

1) A Multiprovider can be built on basic InfoCubes, ODSs, info objects or Infosets. An Infoset can have only ODSs or info objects. Multiproviders use 'union' operation but Infosets use 'join'. Both the objects are logical definitions which don't store any data.

 2)Multiprovider works on the concept of union of all infoproviders but the infoset works on the concept of intersection of the data in the fields available in the different infoproviders.

 3)Multiprovider is 3dim in this infoobject, ods and infocube included.it will works on union concept.

Infoset are 2dim in this infoobject and Ods included. it will works on intersection concept.

 in BI7 infocubes also included in Infosets.

 info cube is 3 dimention data target.
