What is the difference between web scraping and ETL
ETL: Extract, Transform, Load
That's just a fancy way to say that ETL is the process of taking data from one place, massaging it a little, and saving it in another place. Web scraping is one form of ETL: you extract data from a website, transform it to fit the format you want, and load it into a CSV file.
What is the difference between web scraping and web crawling
Web scraping aims to extract the data on web pages, and web crawling purposes to index and find web pages. Web crawling involves following links permanently based on hyperlinks. In comparison, web scraping implies writing a program computing that can stealthily collect data from several websites.

What is the difference between ETL and ETL
In Summary:
ETL stands for Extract, Transform, and Load, while ELT stands for Extract, Load, and Transform. In ETL, data flows from the data source to staging to the data destination. ELT lets the data destination do the transformation, eliminating the need for data staging.
What is the difference between data wrangling and ETL
Data wrangling is the act of extracting data and converting it to a workable format, while ETL (extract, transform, load) is a process for data integration. While data wrangling involves extracting raw data for further processing in a more usable form, it is a less systematic process than ETL.
