Answer
Manual ORM is flexible but requires more code and maintenance.
Manual ORM provides precise control over how database rows map to Java objects, making it flexible for custom logic. However, it involves writing more code, which can be error-prone and harder to maintain, especially as the database schema evolves. For example, manually mapping complex e-commerce order data requires careful handling of each field, increasing the chance of missing or incorrectly mapping fields if the schema changes.
