What is Hibernate Framework in java ?

Hibernate Framework

Hibernate ORM is a stable object-relational mapping framework for Java. It makes better communication possible between the Java programming language and relational database management systems (RDBMS).

When you work with an object-oriented language like Java, you’ll encounter a problem called Object-Relational Impedance Mismatch also called Paradigm Mismatch. This is because OO languages and RDBMSs handle the data differently, which can lead to severe mismatch problems. So, this Hibernate provides you with a framework that overcomes the mismatch problems of Java.

Uses

It allows you to develop persistent classes following the object-oriented idiom
It allows you to communicate with any database using very tiny alterations in the code, bridging the gap between objects and relational words
It is an advanced ORM framework that lets you perform the database operation on Java entities

Advantages

Portability, productivity, maintainability
Free and open source framework
It removes a lot of repetitive code from the JDBC API

Now, talking about the major companies that use Hibernate framework for application development, we have,

Oracle
IBM
DELL
Accenture

Difference between loc() and iloc() in Pandas DataFrame

Difference between loc() and iloc() in Pandas DataFrame Pandas library of python is very useful for the manipulation of mathematical data and is widely used in the field of machine learning. It comprises many methods for its proper functioning. loc() and iloc() are one of those methods. These are used in slicing data from the Pandas DataFrame. They help in the convenient selection of data from the DataFrame. They are used in filtering the data according to some conditions. The working of both of these methods is explained in the sample dataset of cars. loc() : loc() is label-based data selecting method which means that we have to pass the name of the row or column which we want to select. This method includes the last element of the range passed in it, unlike iloc() . loc() can accept the boolean data unlike iloc() . iloc() : iloc( ) is an indexed-based selecting method which means that we ...
