How does a database work?
There are two kinds of databases. RDBMS and DBMS. Anything which stores data in rows and columns can be called as a database. Even a text file can be a database if it contains data in this format. XML files also can be treated as database. We can query a database using SQL (Structured Query Language) to extract information from a database. This data can be manipulated in different ways to generate reports or use in your software.

What is the use of hibernet in Java?
Hibernate is a framework in Java and J2EE which is used to connect to the database in Enterprise class applications. Actually Hibernate is too big a topic to elaborate in one answer but it is used to connect to databases and retrieve/update values. The benefit is that, we need not manually write queries like we do in normal Java database connectivity. Instead hibernate takes care of connecting to the database and picking up or updating the values we need. It does this with the help of hibernate mapping files which are xml files that represent the database schema which we intend on retrieving or updating.
