Fetch data.

This method fetches all data of the dataset/view.
Note that this method returns a column-major data
(i.e. :obj:`([a[0], ..., a[3]], ..., [c[0], ... c[3]])`,
:obj:`{'a': [a[0], ..., a[3]], ..., 'c': [c[0], ..., c[3]]}`, or
:obj:`[a[0], ..., a[3]]`).

Returns:
    If :attr:`mode` is :class:`tuple`,
    this method returns a tuple of lists/arrays.
    If :attr:`mode` is :class:`dict`,
    this method returns a dict of lists/arrays.
