Data extraction and collection are essential components of the data management process and are necessary to obtain high-quality, usable data.
Data collection refers to gathering data from various sources, such as websites, databases, surveys, and social media platforms. The data collected may be unstructured, such as text from a blog post, or structured, such as data from a database table.
Data extraction refers to the process of taking the data collected during data collection and transforming it into a usable format. This often involves filtering and transforming the data, such as extracting content for specific fields, converting text to numerical data, or transforming data into a specific format.
