Summary

Today you examined entity beans, and learned that they are server-side components that represent back-store data in the middle tier. By design, entity beans are persistent and survive any server crashes. They are transactional and share their state with multiple clients. You also learned about both types of persistence: bean-managed and container-managed persistence. You briefly explored the relationship between entity beans. Over the next three days, you will examine the last three topics in more detail with full examples.
