Standard Naming Convention for DAO Methods

Question

Is there a standard naming convention for DAO methods, similar to JavaBeans?

For example, one naming convention I\'ve seen is to use get() to return a s

Answer 1

Usually I name the methods in such way that the name hints the type of the CRUD operation that will be applied by the method, like add*, save* or find*.

• add* can be applied on INSERT operations, like addPhoneNumber(Long userId).

• get* can be applied for SELECT operations, like getEmailAddress(Long userId).

• set* can be applied on method that performs an UPDATE operation.

• delete* can be applied on DELETE operations, like deleteUser(Long userId). Althought I'm not pretty sure how useful is the physical delete. Personally, I would set a flag that denotes that the row is not gonna be used, rather than performing a physical delete.

• is* can be applied on a method that check something, for example isUsernameAvailable(String username).
