The document discusses Java Persistence API (JPA) and Hibernate, which are frameworks that help map objects to relational databases and resolve the impedance mismatch between object-oriented and relational models. JPA is a specification that providers like Hibernate implement. Hibernate is an object/relational mapping tool that provides object/relational mapping, object/relational persistence services, and query capabilities. It generates database schemas from object models and vice versa. The document also provides examples of performing basic CRUD operations using JPA and SQL.
Introduction to JPA and Hibernate including examplesecosio GmbH
In this talk, held as part of the Web Engineering lecture series at Vienna University of Technology, we introduce the main concepts of Java Persistence API (JPA) and Hibernate.
The first part of the presentation introduces the main principles of JDBC and outlines the major drawbacks of JDBC-based implementations. We then further outline the fundamental principles behind the concept of object relation mapping (ORM) and finally introduce JPA and Hibernate.
The lecture is accompanied by practical examples, which are available on GitHub.
This is a basic tutorial on Spring core.
Best viewed when animations and transitions are supported, e.g., view in MS Powerpoint. So, please try to view it with animation else the main purpose of this presentation will be defeated.
A hibernate tutorial for beginners. It describe the hibernate concepts in a lucid manner and and test project(User application with database) to get hands on over the same.

This file contains the Spring Framework introduction.
Mainly about what is Spring Framework and its components, feature, advantages with a simple program example.
Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
In this Java Spring Training session, you will learn Spring – Inversion of Control, Dependency Injection and Bean definitions. Topics covered in this session are:

Spring Framework
• Core Container
• Data Access/Integration
• Web Layer
• Spring Setup
• Key features
• Spring Bean
• Dependency Injection
• Relation between DI and IoC
• Spring IoC Containers
• Spring DI

Spring Data is a high level SpringSource project whose purpose is to unify and ease the access to different kinds of persistence stores, both relational database systems and NoSQL data stores.
The java persistence API provides a specification for persisting, reading, and managing data from your java object to your relational tables in the database. JPA specifies the set of rules and guidelines for developing interfaces that follow standards.

Spring framework makes the easy development of JavaEE application.
Spring is a lightweight framework. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF etc.
Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc.
Hibernate framework simplifies the development of java application to interact with the database. Hibernate is an open source, lightweight, ORM (Object Relational Mapping) tool.
An ORM tool simplifies the data creation, data manipulation and data access. It is a programming technique that maps the object to the data stored in the database.

Java Persistence API (JPA) - A Brief OverviewCraig Dickson
This is a lightning presentation given by Scott Rabon, a member of my development team. He presents a high level overview of the JPA based on his first exposure to it.
Hibernate ORM: Tips, Tricks, and Performance TechniquesBrett Meyer
DevNexus 2014
Out-of-the-box, Hibernate ORM offers limited overhead and decent throughput. Early-stage applications enjoy the convenience of ORM/JPA with great performance. However, scaling your application into an enterprise-level system introduces more demanding needs.
This talk will describe numerous tips and techniques to both increase Hibernate ORM performance, as well as decrease overhead. These include some basic tricks, such as mapping and fetching strategies. Entity enhancement instrumentation, third-party second level caching, Hibernate Search, and more complex considerations will also be discussed. The talk will include live demonstrations techniques and their before-and-after results.

A powerful ORM tool to design data base access layer.
Fills gaps of mismatches between OOPs and RDBMS paradigm. Also maintains adequate ultra performance of database access.
An automated, configurable persistence of java objects with tables in data base.
May not be a good solution for data-centric application which uses only stored procedures to implement business logic in the database.
JAVA EE DEVELOPMENT (JSP and Servlets)Talha Ocakçı
Java and J2EE is the most used technologies in enterprise web development. Telecom operators, service providers are using these technlogies; banking and insurance companies are moving to Java from old generation technologies.

If you want to earn much in web development business, you also need to learn Java web technologies.
Java has de facto standart frameworks such as EJB 3.0, Spring and others that can be bound to them.
But at heart, they all use the similar JSP/Servlet technology and add some layers above them to speed up the development.
You will use them in your daily business but before using them, you must learn the basics and what is going on while using them. Otherwise, you will not be able to find a proper solution to common problems.
This course will make you understand the basics of JSP / servlet technlogies, designing a relational database, DB operations, design patterns, working with other developers,
and let you know the must-do operations in professional projects such as performance increasing, logging errors.
If you want to develop a web-site in a couple of hours without understanding what you are doing, you may go ahead and find other resources. But if you really want to understand what you are doing and learn the theory at the same time, this course will be a great oppurtunity for you. You will develop a real working project. Yow will first write quick and dirty code then you will apply professional patterns one by one while investigating the problems.
You will walk through a real development flow:
1- Write a quick and dirty code for doing the job.
2- You will design database tables and high performance queries
3 - You will apply design patterns to make the code reusable and high performance.
4 - You will beautify the user interface with Javascript and CSS tweaks
5- You will add exception handling, logging mechanism for production environment
6- AT THIS STEP, YOU WILL BE HIRED FOR MUCH MUCH HIGHER SALARIES. BECAUSE YOU ARE A REAL PROFESSIONAL.
Most Rails users are familiar with ActiveRecord. But what does that mean? What is ActiveRecord's approach to object relational mapping? And what are the alternatives?
Hibernate, created by Gavin King, known as the best and dominated object/relational persistence (ORM) tool for Java developers (Now is support .NET). It provides many elegant and innovative ways to simplifies the relational database handling task in Java.
Hibernate is great at a lot of things, but its something that needs to be used appropriately. In this tutorials, it providing many step by step examples and explanations on using Hibernate3.

23. Case Study
• Port legacy FoxPro data to Oracle, optimize, export to JavaDB
• Write new Java web app
• Eight seasoned remote dev’s no JPA/Hibernate experience
• Single code base
• 217 Classes
• 153 Entities
• 107 Pages
