7. Batch Processing

 Batch Processing


- Batch Processing: What Does it Mean?

   Batch processing is a way to efficiently process a large amount of data in chunks or groups, instead of one piece at a time. This is particularly useful when dealing with a large dataset.


-  Batch Processing in Hibernate: Why Use It?

   When you're dealing with a lot of data, doing database operations one at a time can be slow and resource-intensive. Batch processing allows you to group multiple operations together and send them to the database in a single go, reducing the overall time and resources needed.


-  Saving Multiple Objects

   Imagine you have a Java program using Hibernate, and you want to save a hundred new objects to the database. Instead of saving them one by one, you can use batch processing to save, let's say, 20 objects at a time. This means you're making fewer trips to the database, making the process faster.


- Advantages:

   - Performance Improvement: Batch processing reduces the number of database calls, making the overall operation faster.

   - Resource Optimization: It minimizes the usage of system resources because you're dealing with data in chunks, not individually.

   - Batch processing is not suitable for all scenarios. It depends on the nature of your application and the type of operations you are performing.

5. JPA Relational Mapping & Fetch Types & Cascadding

 RelationShip  -OneToOne -OneToMany -ManyToOne -ManytoMany Fetch Types 1. FetchType.LAZY  2. FetchType.EAGER In Hibernate, the "fetch type" determines how associated data should be loaded from the database.  It's like specifying whether you want to load related data eagerly (at the same time as the main entity) or lazily (only when needed). There are two main fetch types in Hibernate: 1. Eager Fetch Type    - When you fetch data eagerly, Hibernate loads the main entity along with its associated data immediately.    - It's like ordering a combo meal at a restaurant – you get the burger and fries together, even if you're not going to eat the fries right away.    - Eager loading can lead to loading more data than necessary, which may impact performance if not used carefully. 2. Lazy Fetch Type:    - When you fetch data lazily, Hibernate loads the main entity first and only loads associated data when explicitly requested. ...

4. Data Fetching Methods & @Embeddable annotation in Hibernate

  Data Fetching from Database In Hibernate, the `get` and `load` methods are used to retrieve an object from the database based on its primary key. Both methods are part of the `Session` interface in Hibernate. 1. get() method: - The get() method is a part of the Hibernate Session interface. - It retrieves an entity(persistence) object from the database by its primary key (ID). -  It takes the class of the object to be retrieved and the primary key of the object as arguments. - get() method only hits the database if the object is not present in the session cache.   - get() method returns null if there is no object present in the database.    Example:       Session session = sessionFactory.openSession();    Transaction transaction = session.beginTransaction();    // Get an object by its primary key    Employee employee = (Employee) session.get(Employee.class, 1L);    transaction.commit();    se...

6. Hibernate Query Language (HQL) & Caching in Hibernate

  Hibernate Query Language (HQL) Hibernate Query Language (HQL) is a powerful and flexible way to interact with a relational database using Hibernate, which is a popular Object-Relational Mapping (ORM) framework in Java.  1. HQL - Hibernate Query Language:    - HQL is like SQL, but it's designed to work with your Java objects, not directly with the database tables. It allows you to write queries using the names of your Java classes and properties, rather than database tables and columns. 2. Database Interaction - In traditional database operations, you use SQL (Structured Query Language) to interact with the database. SQL is a language that is specific to the database you are using (e.g., MySQL, PostgreSQL, Oracle). 3. Object-Relational Mapping (ORM): Hibernate helps you work with databases in a more object-oriented way. Instead of thinking in terms of database tables and SQL queries, you can work with Java objects that map to your database tables. Caching in Hiberna...
