      :parts: 1
      :private-bases:


   A data store for LCI databases. Stores each dataset in a separate file, serialized to JSON.

   Instead of loading all the data at once, ``.load()`` creates a :class:`.SynchronousJSONDict`, which loads values on demand.

   Use this backend by setting ``"backend":"json"`` in the database metadata. This is done automatically if you call ``.register()`` from this class.


   .. py:method:: filepath_intermediate()


   .. py:method:: get(code)

      Get Activity proxy for this dataset



   .. py:method:: load(as_dict=False, *args, **kwargs)

      Instantiate :class:`.SynchronousJSONDict` for this database.



   .. py:method:: register(**kwargs)

      Register a database with the metadata store, using the correct value for ``backend``, and creates database directory.



   .. py:method:: write(data, process=True)

      Serialize data to disk. Most of the time, this data has already been saved to disk, so this is a no-op. The only exception is if ``data`` is a new database dictionary.

      Normalizes units when found.

      :type \* *data*: dict
