What is Hibernate?
Hibernate refers to an object-relational, open-source mapper solution found in Java. It has abstraction layers that let it internally handle the implementations.
Some of the implementations are tasks like writing queries for the CRUD operations or setting connections with a database. Basically, Hibernate is the software that offers abstraction on several technologies, such as Java™ database connectivity (JDBC) and servlet.
The use of persistence logic helps to store and process data for long-term use. Hibernate also acts as an ORM tool. Its lightweight nature makes Hibernate more popular than many other frameworks in the similar category.
Advantages of using Hibernate
Gavin King from Cirrus Technologies launched Hibernate back in 2001. It started as a viable alternative to EJB2 entity beans. Its actual aim was to ensure improved persistence capabilities than EJB2. Hibernate2 came out in early 2003. Hibernate 3.0 came two years after that. Finally, the team released Hibernate ORM 5.4.0 in December 2018.
All changes in Hibernate remain encapsulated in its data source. As the sources and their related APIs change, the applications using ORM do not need to make any changes. Developers get a consistent object view over time. They do not need to notice when its delivery sources, receiving sinks, and accessing applications are changing.
Hibernate does not require extensive coding. The software has object-table mappings within itself. It returns results as Java objects. This means the programmer does not need to deal with manual handling of data. It reduces the cost of maintenance and the time of development.
An expert Hibernate Developer can bring down the cost and time even further.
Why hire a Hibernate developer?
Hibernate developers are in demand because they know the ways to eliminate the drawbacks of technologies like JDBC. Here are more reasons to hire Hibernate developers:
-
Hibernate developers do away with the database dependency of JDBC.
-
They can overcome and strengthen object level relationships.
-
They can change the database at a fraction of the cost needed for JDBC.
-
They reduce code length while improving readability. It helps to overcome boilerplate issues where parts of codes have repetitions at several places.
-
They overcome the exception-handling responsibilities usually present in JDBC.
-
Hibernate developers are better at handling code portability.
Java Developers across the world use JPA and Hibernate or only Hibernate to develop enterprise web applications. Developers can write the database access programs faster using Hibernate.
There are loads of help available online regarding Hibernate usage. Dedicated online Hibernate communities exist. So, if the developer is stuck at any point, assistance is readily available online. It makes their work go even faster.
Responsibilities handled by a Hibernate developer
A Hibernate developer needs to be an expert at Hibernate ORM 5.4.0. It is the latest version of the software. The developer also needs to have brief ideas about the earlier versions of Hibernate. It is of help when creating or improving an application.
An experienced Hibernate developer can handle the following responsibilities:
-
They can work on Auto DDL operations. The DDL operations are internally completed. This makes it easier to create, drop, and alter a table.
-
Hibernate developers are good at Auto Primary key generations.
-
Developers make the most of cache memory to improve the performance of the applications.
-
They are experts at HQL, i.e., Hibernate Query Language. The Hibernate framework needs HQL because it’s independent of databases. It helps that HQL is database independent.
-
Developers work using object relational mapping. It is one of the most important tools of Hibernate. Every record presents itself as an object in hibernate. Developers leverage the objects as per the changes required in an application.
-
They are also good at exception handling and the implementation of this feature when needed.
How to hire Hibernate developers?
Multiple benefits of Hibernate over other frameworks makes the developers highly in demand. Here are the steps to follow to hire the right talent.
-
Send out the job description. Clearly mention the skills, experience, and other details of the job.
-
Mention whether the company needs a full-time or part-time employee. Outline if the company is looking to outsource the job or hire a developer permanently. Outsourcing or hiring part-time makes more sense if the company is not into full-time application development.
-
Shortlist the applications based on the criteria mentioned in the job description and schedule the interview.
-
Explain the details of the job during the interview. Let the candidates have a clear picture of how good they can be at the job.
-
Ask the candidates to explain their previous experience in detail. Enquire the candidates about their prior work responsibilities and existing skill-set.
-
Choose the one with the right technical and soft skills for the job role.
-
Discuss the salary or the charges for the work and hire the candidate.
