The following are the features and characteristics that distinguish web scraping:
- It is an automated process that doesn't require manual intervention
- It involves scripts or bots that crawl through web pages to extract data
- It requires programming knowledge and web development expertise
- It is useful in extracting real-time data from websites
- It is widely applicable in diverse industries and domains where data from websites is crucial
Data Collection: Definition and Features
Data collection is the process of gathering relevant data from various sources and storing it for analysis. This method involves manual data entry, using forms, or any other method of acquiring data. It is a widely used method for data acquisition, especially when the source data is not available in the required format.
The following are the features and characteristics that distinguish data collection:
- It is a manual process that requires human intervention
- It involves systematic collection of data from various sources
- It does not require programming knowledge or web development expertise
- It is less prone to errors than web scraping
- It is useful in acquiring data that is not available on websites
