The only other technology that matches the number of Hibernate jobs is probably Spring. Both are equally important! In this post, we take a look at the genesis of Hibernate, and how you can learn this IT skill which has one of the highest % of jobs in IT / ITES sector in India.
As time passes, technology is bound to evolve. Some, like JasperReports (the feature-rich reporting API in Java) are bound to evolve for good, and build up on their strengths, packing more features with each release.
Some API get their weaknesses exposed. JDBC is one of such technologies.
For the sake of an introduction, let’s have a summary of why JDBC doesn’t satisfy a Java Developer anymore.
For a Java Developer, he has to conduct ALL these steps to save data into / read data from an RDBMS.
The data in an RDBMS is stored in a 2D matrix structure. The fundamental unit of programming in Java is an object. All of your data of your Java application is stored in objects.
Storing data from a Java application into an RDBMS requires format conversion i.e. data must be unpacked to construct SQL queries for writing operations. Each field of the object must be retrieved and inserted into query string – one-by-one!
While reading the data – you must unpack the result set data into usable Java objects. Traverse the whole result set (no matter how long), read individual fields, and construct objects from them.
JDBC works with data at raw-data level
This cumbersome process has led the development industry away from JDBC and toward an exciting new range of database APIs – called ORM (Object / Relational Mapping).
Hibernate is now the most popular ORM framework based on Java. If you are looking for Java-based advanced frameworks, Hibernate is probably the most popular course there is!
Number of jobs in the market are high.
As you can see, a simple search into India’s top 3 job portals reveals that there are over 20,000 jobs based on Hibernate alone.
Here’s another proof of Hibernate’s popularity
The top course for Hibernate on one of the top international course platform (Udemy.com) has over 16,000 students enrolled.
Any course with over 5000 enrollments is considered a huge success. On top of that, over 3000 students have rated it 4.7 / 5.0. so many learners from around the world cannot be wrong!
But these are just numbers and they may be manipulated. So many users can’t be false, so reviews of the course give you a very good idea of the quality of the instructor as well the course.
Here in overview of reviews of this course:
As you can see, a whopping 93% of reviews are 4 / 5 star ratings.
Learn from the best Hibernate Course to get jobs with best salary
This course is delivered by Chad Darby (pronounced shaad).
Chád has Java certifications from Oracle and IBM. He is also a contributing author to several Java books, including Professional Java E-Commerce (Wrox Press), Beginning Java Networking (Wrox Press), and XML and Web Services Unleashed (Sams Publishing).
Let’s first have a look at what you will learn through this course:
- Build a complete Spring MVC and Hibernate CRUD Project … all from scratch
- Set up your Spring and Hibernate development environment with Tomcat and Eclipse
- Wire beans together in the Spring container using Inversion of Control
- Configure the Spring container for Dependency Injection
- Apply Bean Scopes for Singletons and Prototypes
- Customize Bean Lifecycle with your own Init and Destroy methods
- Perform object/relational mapping with Hibernate
- Leverage the Hibernate API to develop CRUD apps
- Apply Java annotations for Hibernate mappings
- Develop queries using the Hibernate Query Language (HQL)
- Integrate Spring MVC and Hibernate together in a Single Application Project
As you can see, the topics start with basics and move on to advanced covering even the most advanced topics such as Hibernate annotations. This is the best coverage I have ever seen!
Being a trainer myself, I know the importance of keeping up to date with the latest versions of ANY technology. A big relief for me was when I saw this course uses Spring 4 and Hibernate 5 – the latest versions of the frameworks!
But anybody who has ever learnt programming knows that attending lectures is only the half part – the practical examples is where the heart of the matter is! And most instructors fail to provide mid-course support promptly.
As I myself learn new technologies, I get errors that take up 4-5 hrs to solve. If you are stuck with such an error, a responsive instructor can come to your rescue.
Unfortunately, I have never personally interacted with Chad. So I cannot guarantee how responsive he is. He claims to be very responsive on his course page.
What about student reviews?
Let’s look at what students of the course are saying about Chad and the course.
If you are looking to secure your future, Hibernate is the best technology to invest in.
Now we have established the proof of Hibernate’s popularity. But still why should you learn Hibernate.
There are several reasons – first and foremost reason being that you are directly working with objects (not raw data) in Hibernate. Secondly, you are not creating queries yourself – Hibernate framework does it for you. This saves a lot of time of the developers.
I have discussed the advantages of Hibernate in detail previously on this blog.
What if I don’t like the course?
Worry not, you get to preview 25% of the course for free, so you can take an informed decision. If after purchasing you don’t like something about it, Udemy provides a 30-day full refund guarantee.
Hope you are excited to learn Hibernate now.
In the next post, I will bringing you a unique way to learn Hibernate, through question and answers. The ideal audience for this next article is beginner-level computer / IT engineering graduates, who are excited to learn Hibernate.
This article is of slightly over 2000+ words and I will publish it in next 3 days. I don’t expect readers to have any technical expertise for this article, but certain level of development exposure will definitely help.
