There areĀ app entriesĀ whose purpose and structure are defined by theĀ DNAĀ developer, and there are specialĀ system entriesĀ such as anĀ agent ID entry.
Entry typeĀ¶
A specification for any sort of entry that aĀ DNAĀ should recognize and understand, similar to anĀ OOPĀ class or database table schema. It can specify whether entries of its type should beĀ publicĀ orĀ private, and how manyĀ required validationsĀ should exist. DNA developers create their own entry types for the data their app needs to store, and can writeĀ validation functionsĀ forĀ recordsĀ thatĀ create, update, or deleteĀ entries of those types.
