![]() They are afraid of Hibernate because it seems to replace their role in the project. It seemed ugly and unreadable will this be a problem in future? Ridiculous! I know! But, here’s the thing: We have really smart SQL guys in the team and when they saw SQL generated by Hibernate they got nervous. In a previous project, we were using mostly SQL via plain old JDBC. Monica - I absolutely agree! I have the same feelings about it. See how many job descriptions require it! If you are writing in Java, this is absolutely the right choice, plus you have ports for other languages. It’s widely used in big, true enterprise solutions, like banks. Hibernate is, indeed, an outstanding tool. He is super smart, and I need some really good arguments to convince him this is a good decision. He knows a lot about databases, and he’s afraid of adding another layer between our application and the database. However, I have an issue with one of our teammates he is totally against it. I’ve heard so many positive experiences with it. A true enterprise solution for a true enterprise problem, proven by the market and with a long history. Monica - Yes! Exactly! Just what I was thinking! It seems like a perfect match and the real deal for us. ![]() Absolutely fantastic! Everybody is so excited! I’ve been promoted to the role of an architect, so now I have to select the stack we will be using. We are planning on becoming the next Facebook or Google. So, we are building our Next Big Thing, you know. Monica - Hey John, glad you found some time for me. He’s a Hibernate expert, and he’s going to help you. Hibernate Sounds Like A Silver Bulletīen - Hello Monica, I’d like to introduce John. Fortunately, her colleague, Ben, knows the right guy. However, it is always a good idea to check a few things before starting a project. ![]() Hibernate is a well known and supported JPA standard. She knows that in the Java world there is only one good tool for handling database communication: Hibernate. Monica has recently been promoted to the role of architect and is now responsible for laying out the technology stack for a new product at her company. Let’s take a look at what can go wrong if you blindly use Hibernate just because it’s the accepted standard.Ĭonsider Monica, a Java developer. The obvious answer is to just use Hibernate, right? 90% of Java developers would agree with you, but does that make it the right decision? You want to support all kinds of data, and ideally, support all sorts of databases. You want to pick the best object-oriented abstraction of your flexible data model because you do not want to deal with plain SQL. You need to make the fundamental decisions that will stick with you for the rest of the project. Hibernate supports Query cache and provide statistics about query and database status.Imagine that you are a Java developer, and you’re about to start your next big project. 6) Provides Query Statistics and Database Status 5) Simplifies Complex Joinįetching data from multiple tables is easy in hibernate framework. So there is no need to create tables in the database manually. Hibernate framework provides the facility to create the tables of the database automatically. Before Hibernate, if database is changed for the project, we need to change the SQL query as well that leads to the maintenance problem. ![]() So you don't need to write database specific queries. It generates the database independent queries. HQL (Hibernate Query Language) is the object-oriented version of SQL. There are two types of cache in hibernate framework first level cache and second level cache. The performance of hibernate framework is fast because cache is internally used in hibernate framework. Hibernate framework is open source under the LGPL license and lightweight. Advantages of Hibernate Frameworkįollowing are the advantages of hibernate framework: 1) Open Source and Lightweight The javax.persistence package contains the JPA classes and interfaces. Java Persistence API (JPA) is a Java specification that provides certain functionality and standard to ORM tools. The ORM tool internally uses the JDBC API to interact with the database. It is a programming technique that maps the object to the data stored in the database. Hibernate implements the specifications of JPA (Java Persistence API) for data persistence.Īn ORM tool simplifies the data creation, data manipulation and data access. It is an open source, lightweight, ORM (Object Relational Mapping) tool. Hibernate is a Java framework that simplifies the development of Java application to interact with the database. It was started in 2001 by Gavin King as an alternative to EJB2 style entity bean. This hibernate tutorial provides in-depth concepts of Hibernate Framework with simplified examples.
