If you’ve ever struggled with setting up pipelines for extracting, transforming, and loading data (so-called ETL jobs), managing different databases, and scheduling workflows – know that there’s an easier way to automate these data engineering tasks. In this article, you’ll learn how to build an n8n workflow that processes text, stores data in two databases, and sends messages to Slack.
A few months ago, I completed a Data Science bootcamp, where one week was all about data engineering, ETL pipelines, and workflow automation. The project for that week was to create a database of tweets that use the hashtag #OnThisDay, along with their sentiment score, and post tweets in a Slack channel to inform members about historical events that happened on that day. This pipeline had to be done with Docker Compose and included six steps:
1. Collect tweets with the hashtag #OnThisDay
2. Store the collected tweets in a MongoDB database
3. Extract tweets from the database
4. Process the tweets (clean the text, analyse sentiment)
5. Load the cleaned tweets and their sentiment score in a Postgres database
6. Extract and post tweets with positive sentiment in a Slack channel
This is a fun project that offers lots of learning opportunities about different topics: APIs, text processing with Natural Language Processing libraries, both relational and non-relational databases, social media and communication apps, as well as workflow orchestration. If you’re wondering, like I did, why we had to use two different databases, the answer is simple: for the sake of learning more. Postgres and MongoDB represent not only different database providers, but different kinds of database structures – relational (SQL) vs non-relational (NoSQL) – and it’s useful to be familiar with both.
Though our use case is just for fun, this pipeline can support most common data engineering tasks (e.g. aggregating data from multiple sources, setting up and managing the data flow across databases, developing and maintaining data pipelines).
I was really excited, though also a bit overwhelmed by all the things I had to set up for this project. In total, I spent five days learning the tools, debugging, and building this pipeline with Python (including libraries like Tweepy, TextBlob, VADER, and SQLAlchemy), Postgres, MongoDB, Docker, and Airflow (most frustrating part…). If you’re interested to see how I did this, you can check out the project on GitHub and read this blog post.
But in this article, I’ll show you an easier way to achieve the same result in as much as an hour – with n8n!

Finding the right database solution for your application is not easy. At iQIYI, one of the largest online video sites in the world, we’re experienced in database selection across several fields: Online Transactional Processing (OLTP), Online Analytical Processing (OLAP), Hybrid Transaction/Analytical Processing (HTAP), SQL, and NoSQL.
Today, I’ll share with you:
I hope this post can help you easily find the right database for your applications.

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

There are five system databases, these databases are created while installing SQL Server.

A simple Boilerplate to Setup Authentication using Django-allauth, with a custom template for login and registration using django-crispy-forms
.
# clone the repo
$ git clone https://github.com/yezz123/Django-Authentication
# move to the project folder
$ cd Django-Authentication
virtual environment
for this project:# creating pipenv environment for python 3
$ virtualenv venv
# activating the pipenv environment
$ cd venv/bin #windows environment you activate from Scripts folder
# if you have multiple python 3 versions installed then
$ source ./activate
SECRET_KEY = #random string
DEBUG = #True or False
ALLOWED_HOSTS = #localhost
DATABASE_NAME = #database name (You can just use the default if you want to use SQLite)
DATABASE_USER = #database user for postgres
DATABASE_PASSWORD = #database password for postgres
DATABASE_HOST = #database host for postgres
DATABASE_PORT = #database port for postgres
ACCOUNT_EMAIL_VERIFICATION = #mandatory or optional
EMAIL_BACKEND = #email backend
EMAIL_HOST = #email host
EMAIL_HOST_PASSWORD = #email host password
EMAIL_USE_TLS = # if your email use tls
EMAIL_PORT = #email port
change all the environment variables in the
.env.sample
and don't forget to rename it to.env
.
After Setup the environment, you can run the project using the Makefile
provided in the project folder.
help:
@echo "Targets:"
@echo " make install" #install requirements
@echo " make makemigrations" #prepare migrations
@echo " make migrations" #migrate database
@echo " make createsuperuser" #create superuser
@echo " make run_server" #run the server
@echo " make lint" #lint the code using black
@echo " make test" #run the tests using Pytest
Includes preconfigured packages to kick start Django-Authentication by just setting appropriate configuration.
Package | Usage |
---|---|
django-allauth | Integrated set of Django applications addressing authentication, registration, account management as well as 3rd party (social) account authentication. |
django-crispy-forms | django-crispy-forms provides you with a crispy filter and {% crispy %} tag that will let you control the rendering behavior of your Django forms in a very elegant and DRY way. |
