What are the best practices for using Data Access Objects (DAOs)?
An example of an AI chatbot conversation about best practices for Data Access Objects in software development.
What are the best practices for using Data Access Objects (DAOs) in my application?
Best practices for DAOs include keeping them simple, ensuring they are reusable, and separating concerns. You should also use interfaces to define your DAOs.
How can I ensure my DAOs are reusable across different parts of my application?
To ensure reusability, design your DAOs to be generic and parameterized. Use interfaces to define common methods and avoid hardcoding specific queries.
What should I avoid when implementing DAOs?
Avoid tightly coupling your DAOs with specific database implementations. Also, steer clear of including business logic within your DAOs.
Can you give an example of a simple DAO implementation?
Sure! A simple DAO for a User entity might include methods like findById, save, and delete, all interacting with a database connection.
