Claim 11:
12. The storage system according to claim 11, wherein
the processor performs read processing when receiving a read request,
the read request is a request for reading of a read target multidimensional dataset and is a request designating a scale and addresses for each of the data dimensions of the multidimensional dataset, and
the read processing includes:
specifying, based on the logical-physical information, a physical address corresponding to the scale and the addresses for each of the data dimensions designated by the read request;
reading the encoded dataset from a storage area represented by the specified physical address; and
returning a multidimensional dataset in the scale designated by the read request, the multidimensional dataset conforming to a dataset obtained by subjecting the read encoded data to decoding processing.
