> Actually, I am using this branch locally and I noticed that we only have
dag<->dataset-alias relationships, but we don't have any
dataset<->dataset-alias edges. Is that not possible?
That's possible. We just need to confirm what the dag dependencies we
actually want. What I'm doing now is something like
```mermaid
flowchart LR
dataset_1 --> dataset_alias_1
dataset_2 --> dataset_alias_1
dataset_3 --> dataset_alias_1
dataset_alias_1 --> DAG_1
DAG_1 --> dataset_alias_2
dataset_alias_2 --> dataset_4
dataset_alias_2 --> dataset_5
```
This means `DAG_1` set `schedule=DatatsetAlias("datset_alias_1")` and
`outlets=[DatasetAlias("dataset_alias_2")]`. `datset_alias_1` can be resolved
in to dataset 1 ~ 3 while `dataset_alias_2` can be resolved into dataset 4 ~ 5.
