Initial thoughts:

Relational Databases are naturally temporal heterogenous graphs, and can be natively modeled in tgm.
A key idea is to identify atomic path from RelGNN paper to identify which tables should be naturally temporal attributes.

Ideas for converting tables into edge features (must satisfy all conditions):

1. if the table has two columns which are primary keys from two other tables
2. if the table has timestamps
3. if the table is a leaf node

Ideas for converting tables into dynamic node events (must satisfy all conditions):

1. has exactly one primary key from other table as column
2. has a date
3. it is also a leaf node
