Data scraping is a technique that allows someone to extract data from a particular website or system. It is usually also known as data extraction.
In general, data extraction is something that is used for several jobs related to digital marketing, such as content research.
One way that can be used to extract data is by utilizing the Application Programming Interface (API). The API allows you to access a site with a more structured data format.
However, this method won't work on a website or system that doesn't have an API or doesn't allow you to access its structured data.
You can do data extraction by using special tools. There are many types of data extraction tools that you can use, but each tool has a different path. In general, the process for extracting data includes three stages:
Some examples of tools for extracting data are Data Scraper, Data Scraping Crawler, and Data Miner. You can choose which tools you think are the easiest to operate.
After knowing what scraping data is and how it works, you need to know what the types are.
In general, data extraction techniques are divided into two categories: screen scraping and web scraping. Let's check out the full explanation below.
Screen scraping is a data extraction technique whose data is obtained by analyzing the interface of a website. In general, this technique scrapes images, text, or other visual elements to form ideal data.
This screen scraping technique is usually used by large companies that want to store crucial data and store it for a long time. This technique is very suitable for data migration because screen scraping can access old data with a high degree of accuracy.
Basically, web scraping involves two elements, namely crawlers and scrapers. Crawler is an algorithm that searches for certain data. A scraper is a tool used to extract data from a website or a particular system.
