Guide to Database Connection in Python

Importance of Database Connection

Connecting to a database is one of the most important tasks that developers must perform in any project. This connection allows for the storage and retrieval of information, playing a crucial role in the performance and efficiency of the application.

Types of Databases

Databases are primarily divided into two main categories:

1. SQL Databases: These databases use SQL (Structured Query Language) to manage data. Popular SQL databases include MySQL, PostgreSQL, and MariaDB.

2. NoSQL Databases: These databases use a non-relational data model for storing data. Well-known NoSQL databases include MongoDB, Redis, and ElasticSearch.

caution

• If you are using Kubar's database in your project, you can use the internal IP of the database in the host variable when connecting.
• The environment variables used in the database connection parameters must be set up on the Kubar site.
