Data Types

The data types available are those available in postgresql

notes

• for each table, an auto-generated type column named id is required
• attributes starting with an underscore are reserved
• camel case attributes are transformed into snake case.
  • For example attributeName will map to column attribute_name - the behaviour is undefined if there are 2 attributes attributeName and attribute_name for one entity type as the resulting column names are the same.
