Data extraction is the procedure, which involves data retrieval from different resources. Often, companies scrape data to have it more, migrate data to the data repository like a data lake or a data warehouse, or to extra analyze it. It’s easy to transform data as a portion of this procedure. For instance, you may want to do data calculations — such as sales data aggregation — and store results in the data warehouse.
In case, you are scraping data for storing it in the data warehouse, then you may need to add extra metadata or improve data using timestamps or geo-location data. In the end, you wish to combine data with different data in the targeted data store. These procedures, together, are known as ETL (Extraction, Transformation, & Loading).
Data Extraction Use Cases:
Just like data mining, web data extraction is widely utilized in different industries to serve various objectives. Besides price monitoring in the e-commerce industry, data extraction could help in paper research, marketing, news aggregation, travel & tourism, real estate, finance, consulting, and more.
Lead Generation:
Companies can scrape data from different directories like YellowPages, Yelp, CrunchBase, as well as produce leads to doing business development.
News & Content Aggregation:
Content aggregation sites can have constant data feeds from different resources as well as keep the websites updated.
Sentiment Analysis:
Once scraping the online comments, feedback, or reviews from social media sites like Twitter and Instagram, people could analyze the fundamental attitudes as well as get an idea about how they are observing a product, brand, or wonder.
