Can pandas be used as a database backend for persistent storage?

−1

Question

What is the current state of the art database app? How does it compare to SQL? Can pandas be used in place of either?

If not, is there something that bridges the gap between SQL and pandas or the current state of the art?

Context

I have become proficient in pandas and have come to like the syntax. I have experience with SQL, but would have to study my notes to get back up to speed, and find the syntax rather tedious.

You can use Pandas to_sql method to upload records to a relational database.

However, be aware this functionality is aimed at using Pandas for its original purpose (data analytics and transformations), so that Pandas can make complex processing and send the results to a SQL table, but it is not advisable to write a traditional "database app" using Pandas as the database connector, since it will be slow performing and less scalable (Pandas is not meant for high throughput applications).

You can use an ORM like Django ORM or SQLAlchemy if writing bare SQL is annoying for you.

ORM is not noob-friendly (2 comments)

Worth saying that ORMs are very complex, advanced things. They require advanced knowledge of both SQL and Python. If either is lacking, things will be very confusing.

Moreover, unless you are doing some very complicated stuff (eg. large codebase maintained over years), the ORM often creates more busywork than it takes away.

I really would not recommend an ORM as a way of escaping the need to learn SQL.

I second the need to know SQL but ORMs also simplify stuff. It doesn't have to get very complicated to profit from an automatic mapping between objects and records in a database. It takes away the boilerplate code to do this manually or to write an abstraction which ends up being somewhat an ORM itself. Reinventing the wheel.

SQLAlchemy doesn't enforce the ORM though. There is core layer which allows to build SQL queries programmatically without the danger to introduce errors or even security risks, that often comes with handling all with just string operations that contain SQL fragments. Another benefit is the abstraction over differences in SQL syntax of RDBMS. Like which placeholders are used, which characters to quote names, if there is a native boolean type or not, and so on.

Pandas implies SQLAlchemy. The only guaranteed exception that can be used without it is SQLite3.
