The same goes for analysis that creates output datasets instead of just scalars. The key
point here is to transition from thinking of the HDF5 container as a
file
to treating it as
a
database
.
Don't get carried away. Keep backups of your data in case you acci‐
dentally do something wrong.
We've covered the four main objects in the HDF5 universe: files, groups, datasets, and
attributes. Now it's time to take a break and talk about the HDF5
type
system, and what
it can do for you.
