Jakarta Persistence (JPA) Method in jakarta.persistence. Basic FetchType fetch (Optional) Whether the value of the field or property should be lazily loaded or must be eagerly fetched. The EAGER strategy is a requirement on the persistence provider runtime that the associated entity must be eagerly

Jakarta Persistence (JPA) Method in jakarta.persistence. Basic boolean optional (Optional) Specifies whether the value of the field or property may be null. This is a hint and is disregarded for primitive types; it may be used in schema generation to infer that the mapped column is not null

with @ElementCollection, in the other case with @ Basic . Is @ Basic also a valid annotation for a Map field? And when it is valid why @ Basic is faster at runtime. @Entity public class TestEntity { @ElementCollection private Map values = new HashMap (); @ Basic private Map values = new HashMap (); } best regards

This chapter demonstrates basic ObjectDB and JPA concepts by introducing a simple example program. After reading this chapter you should be able to write basic programs that create, open and close ObjectDB databases and perform basic CRUD operations (Create/Store, Retrieve, Update and Delete

This chapter introduced the basic principles of JPA using ObjectDB. You can go into details by reading the other chapters of this manual. If you prefer to get started with ObjectDB right away you can follow one of the following tutorials to create and run the example program that was described in

This chapter explains how to manage ObjectDB databases using the Java Persistence API (JPA). The first two pages introduce basic JPA interfaces and concepts: The next section explains how to use JPA for database CRUD operations: More advanced topics (e.g. locking and events) are discussed in the last section:

Welcome to ObjectDB for Java/JPA Developer's Guide. Here you can learn how to develop database applications using ObjectDB and JPA (Java Persistence API). The main purpose of this guide is to make you productive with ObjectDB and JPA in a short time. Guide Structure Demonstrates basic database
