How does data preparation work?

The practice of cleaning and changing raw data before processing and analysis is known as data preparation. Prior to processing, this critical stage frequently entails reformatting data, making enhancements, and combining data sets to enrich data.

For data specialists or business users, data preparation is a never-ending effort. However, it is crucial to put data into context in order to gain insights and then be able to remove the biased results discovered as a result of bad data quality.

For instance, standardizing data formats, improving source data, and/or removing outliers are all common steps in the data construction process.
