Does Python Have Its Own Database
![](https://yugasa.com/public/wp-content/uploads/2022/05/python-1.png)
Python database Library: A database is an abstraction of an operating system's file system that allows developers to create, read, update, and remove persistent data more efficiently. At their most basic level, Web applications store data and show it to users in a meaningful manner. For example, Google saves data on roads and gives directions for driving from one area to another using the Maps program. Because the information is recorded in an organized fashion, driving directions are feasible. Databases enable organized storage to be both dependable and quick. They also provide a conceptual model for how data should be kept and accessed, so you don't have to figure out what to do with it every time you create a new app.
Relational databases

The following are examples - Python database Library
● A master database and one or more read-only secondary instances replicate data. ● sophisticated column kinds, such as JavaScript Object Notation that can store semi-structured data effectively (JSON) ● Sharding enables the horizontal scalability of numerous databases that act as read-write instances at the expense of data consistency delay. ● database schemas and tables monitoring, statistics, and other relevant runtime information Web applications often begin with a single database instance, PostgreSQL, with a simple schema. As database use grows, sophisticated capabilities like replication, sharding, and monitoring become increasingly valuable.The most popular databases for Python web applications
PostgreSQL and MySQL are two of the most popular open-source databases for storing Python web application data. SQLite is a disk-based database that is stored in a single file. SQLite is included with Python; however, it can only be accessed by one connection at a time. As a result, it is strongly advised against using SQLite in a production web application.Database- PostgreSQL
For dealing with Python online applications, PostgreSQL is the preferred relational database. The feature set, active development, and reliability of PostgreSQL contribute to its widespread use as the backend for millions of web-based applications today.Database- MySQL
MySQL is another open-source database that may be used with Python applications. MySQL has a short learning curve than PostgreSQL; however, it lacks several features.Using Python to connect to a database
A code library is required to operate with a relational database in Python. The most common relational database libraries are as follows: ● psycopg2 for PostgreSQL. ● MySQLdb is a MySQL database. Note that this driver's development is essentially halted. Thus if you're using MySQL as a backend, you should look into other options. ● cx_Oracle for Oracle Database. Because SQLite support is incorporated into Python 2.7+, a separate library is not required. To connect to the single file-based database, just "import sqlite3."Object-relational Mapping
ORMs (object-relational mappers) enable developers to retrieve data from a backend using Python rather than SQL queries. The integration of ORMs is handled differently by each web application framework. You should read a whole page on object-relational mapping (ORMs) to understand this topic better.Third-party database services
As a hosted service, several organizations provide scalable database servers. Depending on the supplier, hosted databases may typically include automatic backups and recovery, tighter security parameters, and simple vertical growth. ● Pre-configured MySQL and PostgreSQL instances are available via Amazon Relational Database Service (RDS). Depending on storage and performance requirements, the cases may be scaled up or down. ● Google Cloud SQL is a service that provides MySQL instances that are managed, backed up, replicated, and auto-patched. Cloud SQL works with Google App Engine but may also be used independently. ● BitCan hosts MySQL and MongoDB databases and offers comprehensive backup services. ● ElephantSQL is a software-as-a-service provider that runs PostgreSQL databases on Amazon Web Services instances and manages server setup, backups, and data connections.Resources for SQL
