Maven hibernate postgresql tutorial1/25/2024 ![]() These are but a few of the alternatives for Hibernate, there are definitely even more libraries and frameworks out there that suit many different scenarios and databases. ORMLite which is a lightweight framework to persist Java objects to SQL databases.Ebean which can be used for both Java and Kotlin-based applications.MyBatis is an SQL mapper framework to integrate relational databases.JDBI provides access to relational data in Java in a convenient way.JOOQ (Java Object Oriented Querying) is a light database-mapping software library.Hibernate is not the only ORM framework that we can use in our Java applications, others include: It's a stable framework that has been around for 18 years.By creating tables automatically, the developer can focus on doing other logic.It provides the functionality to simplify joins when fetching data from multiple tables.It is database-independent, which means it can be used to access and manipulate data in various different databases.Hibernate utilizes a cache internally that enhances its performance.It is open-source and lightweight, which means that it's free to use and has a community of contributors constantly improving it.Some advantages of using Hibernate include: It works by mapping an object created from a Java class and its attributes, to data stored in the database. Hibernate is a lightweight and open-source tool that simplifies the creation, manipulation, and access of data from a database in Java-based applications. It is an implementation of the Java Persistence API (JPA), which means that it can be utilized in any system that supports JPA, such as the standard edition (Java SE) and the enterprise edition (Java EE). Hibernate is a framework that enables developers to easily persist application data in relational databases using JDBC. Due to the abstractions introduced by an ORM, the developer may lose understanding of SQL and how database management is achieved behind the scenes.For complex queries like joins, ORMs sometimes cannot substitute raw SQL queries.ORMs have a tendency to be slow in some situations performance-wise.However, there are some drawbacks associated with ORMs and they include: Once a model is designed and manipulation code is written, it does not need to be done again, hence making the code easy to update, maintain, and reuse. Other benefits of using an ORM includes speeding up of the development process since the developers do not have to write the database access code and repeat it every time they want to access a database. An ORM helps bridge that difference and plug in our software into different database systems with ease. For example, to interact with a MySQL database, we need to use the Structured Query Language (SQL), but these languages may differ from platform to platform.įor example, while they are still similar, the syntax on a PostgreSQL database is different from the query language used on a Microsoft SQL database. ![]() Normally, we need to use a database-specific language to interact with a database. Our code is now mapped to the databases' specific query language. This technique also helps us convert data between incompatible systems using object-oriented programming applications.Īn ORM is a library that helps us interact with multiple databases or systems easily using our language of choice. Object-Relational Mapping (ORM) is a technique of mapping such objects and their attributes in the database through Object-Relational Mappers. ![]() For instance, a phone can be modeled as an object with attributes such as its name, operating system, manufacturer, and much more as its attributes and this can be easily manipulated and stored in a database. In many systems, real-life objects are modeled as objects in systems to ease the representation and manipulation of their attributes. It is for this reason, and many more, that safe storage and manipulation of data have become an important aspect of any system or application that is built. Information is increasingly becoming more valuable as technology advances and opens up more opportunities for its use. As the use of software becomes more common and more and more systems are built to handle various tasks, data plays a more important role in the current and future technology scene. ![]()
