Hasura + SQL (OLTP)

What do people like doing with SQL DBs?

• Normalize their data so that its easy to ensure consistency
• Read short amounts of related data quickly by specifying filter/sort predicates
• Write data in transactions to ensure consistency

The Hasura + X story:

• Tables, views and functions that return relations become models
  • Models
• A transaction becomes a command that takes an input model, whose body is the invocation of the transaction, and the output relation is the output model
