Notes
- 1.
A relational database is a collection of sets of data items, each of which is formally described and organized. Rules can be put into place for the data such that it can be validated, and indexes can be created such that the data can be queried and updated quickly and safely.
- 2.
Well, perhaps an ideal world in which an ORM is used for data access. But in this book this can be assumed to be the case.
- 3.
See http://docs.jboss.org/hibernate/orm/4.2/quickstart/en-US/html/ch02.html#hibernate-gsg-tutorial-basic-entity for more details. Short form: Hibernate uses reflection to construct an object before data population. The shortest (and quickest) path to doing that is with a no-argument constructor.
- 4.
Go figure; who knew coders like for things to be code? (Besides coders, I mean.)
