# Create the initial system- relation with information about
# distributed d(f)arrays: 
# RelName: the distributed relation on master
# ArrayRef: name of the object storing the distributed array
# DistType: the type of the distributed array. Allowed values are "dfarray"
#  (file based array) and "darray" (array stored in db)
# Slots: the number of slots
# PartType: indicates the way how the relation is partitioned. Allowed values
#  are modulo(d(f)distribute2), random(d(f)distribute3), 
#  function(d(f)distribute4), share (replicated) 
# PartAttribute: the attribute used to distribute the relation, for a random 
#  distribution the value is always "*"
# PartParam:
