Java Hibernate Online Training
- Use easy API to handle all create-read-update-delete activities ; no SQL
- Generates DDL scripts such as tables, limitations and games to generate DB schemas
- Flexibly tunes SQL and calls stored processes to optimize efficiencyUse
- Settings files to modify the database
- Java hibernate can be expanded and configured extremely
Hibernate mapping and setup: Mapping can be described as the mechanism for putting object characteristics in tables sections. While writing a hibernate application, you can build one or more mapping files. The ORM instrument can be mapped in the form of annotations or in the form of an XML.
Hibernate query language: HQL is a straightforward, versatile and effective SQL extension that performs all relational database activities without writing complicated database queries.
Persistence can be described as converting information from the application to survive the process of implementation. Simply put, persistence is nothing but a table-representing example of POJO (plain ancient java objects). If you create any table adjustments or manipulate the item in the table, hibernate will also supervise and create the same table adjustments. Persistent object exists in the memory and even exceeds the process duration that creates it. These items, however, are stored in the database.
Section 1: introduction
In this part, you will get to know about the concept of java hibernate with simplified examples. The introduction part basically deals with hibernate framework, hibernate architecture, advantages of hibernate. You will be able to gain basic knowledge on java hibernate training.
Elements of hibernate architecture
They are as follows:
- Configuration object:
This is the first hibernate object you create in any hibernate application and is usually created once during initialization. It represents configuration file required by hibernate. It has two key components
- Class mapping setup: creates a connection between java classes and database tables.
- Database connection: it handles files that are configured and supported by hibernate
- Session factory:
The session factory holds second level cache (optional) of data. It is a thread safe object and is used by all thread in an application. So you can use multiple databases to create multiple session factory objects.
- Session object:
It provides a physical connection between the application and data stored in the database. The session object are not thread safe therefore, it can’t be kept open for a long time. The session object is designed to instantiate each time when it is needed to interact with the database.
- Transaction object:
The transaction object is optional and specifies the atomic unit of work.in hibernate transactions are handled by transaction manager.
- Query object:
Query object use HQL or SQL string to create object and retrieve data from the database.
Section2: java hibernate examples
We provide java hibernate application examples in step by step process by using hibernate technology which makes simple for you to create application using java. You will learn about creating table, mapping configuration file and setting up tables through these examples.
Section 3: hibernate annotation
The newest way to define mapping without using XML file is through hibernate annotation. Here we can learn about Hibernate hbm2ddl.auto Property and how can it make the application more portable and how it represents the mapping information with hbm2ddl.auto Using Annotation. We have also mentioned running the Program on Java Hibernate Annotation.
Section 4: Mapping TPH (table per hierarchy)
Here we get a brief knowledge about java hibernate mapping TPH so that we can map the whole hierarchy in a single table. We also provide examples for running the program on TPH.
Section 5: Mapping TPC (table per concrete)
Learn more on java hibernate mapping TPC and run your programs on TPC using the processes that has been set up including more variables on java hibernate mapping TPC.
Section 6: Mapping TPS (table per sub class)
Another form of mapping is TPS, so we have introduced you to java hibernate mapping TPS which will help you in learning many techniques of mapping.
