Perhaps you work in data engineering and you need to build an automated ETL pipeline. In this case, you'd need to connect a SQL database so you can store the data coming from the web application. As I mentioned earlier, you might be working on a web application. There are many use cases for when someone would want to connect Python to a SQL database. You might be wondering, "why should I care about connecting Python and a SQL database?" ![]() You'll be able to write those statements with less latency than what a SQLite database would give you. Longer insert, update, and select statements need a lot of computing power. They'll provide long-term infrastructure and bolster your security.Īnother reason they're great for enterprises is that they can handle high performance activities. If you need to scale fast, MySQL and PostgreSQL are your best bet. That said, given the context of the article, they fit into a similar category.īoth database types are great for enterprise solutions. There are distinct differences between MySQL and PostgreSQL. You won't be able to customize features or add a ton of multi-user functionality. That said, you'll be stuck with limited functionality. The pros are that you can move faster with a SQLite database relative to MySQL and PostgreSQL. If you're creating an MVP or don't need a ton of data storage space, you'll want to go with a SQLite database. This means that you don't have to install an extra application or use a separate server to run the database. SQLite is best known for being an integrated database. The rest of the article will use terms referenced in Sameer's article. If you aren't familiar with relational databases (RDBMS), I suggest you check out Sameer's article on basic RDBMS terminology here. The code will show you how to write a SQL query to pull data from a PostgreSQL database and store the data in a pandas data frame. And I'll end the article with some Python code. I'll explain the key differences of each database and the corresponding use cases. I'll talk about the most popular databases, SQLite, MySQL, and PostgreSQL. In this article I'm going to share with you how Python and the different SQL databases interact. ![]() Of the many tools I've used, Python and Structured Query Language (SQL) are two of my favorites. Over the years I've had the opportunity to work with different types of software and tools. ![]() One of my greatest joys as a developer is learning how different technologies intersect.
