You could say that the dialect is like the “translation tool” between Hibernate and its core database. These files are used to connect the Hibernate database with the Java class. Question 7: Define ‘dialect’.Ī dialect can be a singular file or a group of files (the latter is more often the case). The syntax is an important aspect of Hibernate, so you are bound to get asked to provide multiple different answers and examples concerning and involving it. To create a SQL query in Hibernate, you would have to use this line of syntax:ĭon’t be surprised if you get this and similar Hibernate interview questions during your job interview. Question 6: What is the syntax to create a SQL query? However, here are just a few of the more notable ones: support for JPA and XML annotations, fully object-oriented, easily integrated with other various Java frameworks, automatic key generation. The Hibernate framework provides a lot of benefits for developers and programmers alike, so you truly do have a wide variety to choose from. Question 5: Name a few Hibernate benefits. It’s the very basic concept that Hibernate is built upon, and is derived from Java (it is an object-oriented programming language). The way that it achieves this is by (quote on quote) mapping objects according to their data. ![]() It is a philosophy that is aimed at making data manipulation and access as simple as possible. ORM is an acronym for “object-related Mapping”. Question 3: What is the criteria API?Ĭriteria is a powerful API that is simple to use and which is used to retrieve entities through criteria object composition. It is important to know as many abbreviations as possible in the Hibernate interview questions, it will help a lot. Using JPA helps in writing implementation independent code. Java specifications are defined with annotations in javax.persistence package. It provides a specification for managing the relational data in the application. JPI for shortened means Java Persistence API. This is great because it saves developers and programmers a lot of time - something that has huge value when it comes to programming! Hibernate also has inbuilt object mapping - this minimizes the number of lines of code needed for the apps to function. These objects can then be written without any specific SQL knowledge. A great feature of the framework (and one of the main ones that it is loved for) is that it represents the database in the form of objects. It is designed to create database-based apps. You are likely to encounter similar Hibernate interview questions through ought the job interview - ones that require you to explain a concept or define something. Only 17 Left Question 1: Describe Hibernate.Ī great example of a first question that you’re likely to get during your job interview, your potential employers are going to test your skills in describing the framework. Even so, it is key to know these questions and answers, for they might become the deciding factor between you doing great in your interview, and flunking it completely. These are examples of questions that you might get at the beginning of your job interview, or if Hibernate isn’t the main framework that your employers are looking for. The first part of this tutorial is dedicated to some of the more simple questions. Question 10: What is the main benefit of the Eclipse plugin? Question 9: Name the default cache in Hibernate. Question 8: Name and define the three states of objects in Hibernate. Question 7: Can you implement ‘Join’ into Hibernate by using SQL? Question 6: Should your use default Hibernate templates? Question 5: Explain ‘persistent classes’ in Hibernate. ![]() Question 4: Should you use POJOs in Hibernate? Question 3: What is the purpose of ‘caching’ in Hibernate? Question 1: Name some of the advantages that Hibernate has over JDBC. Question 15: What are the two types of collection in Hibernate? Question 14: What’s the syntax of adding a criterion into the SQL query? Question 13: How can you configure Hibernate? Question 12: What is a ‘Hibernate Session’? Question 11: What is the Hibernate configuration file? ![]() Question 10: Name three of the main components of Hibernate. Question 9: How is it possible to enhance the functionality of built-in interfaces by add new custom interfaces? Question 8: Where are the mapping documents located within the framework? ![]()
