Hibernate Basics

Course Summary

Most meaningful applications you will write will have a database associated with it. Knowing how to connect with and incorporate this data is critical to success as a Java developer. In this course, we'll cover how to connect a Java application to a database using what's called JDBC, or Java Database Connectivity. Then, we'll use the convenient approach of including an ORM, or Object Relational Mapper. This will allow us to interact with our data using object-oriented techniques instead of exclusively relying on hard-coded SQL. The ORM we will use is called Hibernate, and is one of the most popular ORMs available.

    Course Syllabus

    Data Persistence & ORMs

    During this stage, we'll start by practicing the basic SQL CRUD operations in a SQL Playground. Then, we'll use workspaces to connect a Java application to a SQLite database using JDBC, or Java Database Connectivity. Finally, in an attempt to map Java objects to database tables, we'll build a case for incorporating the all-inclusive solution of an Object Relational Mapper such as Hibernate. 9 steps

    Getting Started with Hibernate

    After stretching our database and SQL muscles, we're now ready to incorporate an Object Relational Mapper, or ORM. In this stage, we'll configure our Java application to work with Hibernate. To instruct Hibernate as to how we wish to map our POJOs/entities to database tables and columns, we'll employ JPA annotations. 10 steps

    Persisting Data with Hibernate

    Now that we have our application configured to use Hibernate, it's time to see how all the CRUD operations are performed using Hibernate. During this stage, we'll see how to write the code for actually creating, reading, updating and deleting entity objects with the Hibernate SessionFactory. 8 steps
