data-access

• entities that are persisted are called domain objects, so I'll now place them under domain package
• also another way to know if a class is a domain class or not is that if it needs [[@Entity]] annotation then it is
• all stuff related to data access and interfacing over dbs is called a [repository] in [spring]

how to load data into the application?

• data loading in [spring] is covered [data-loading-spring]
