You can also access a summary of changes made to your datasets with the help of a report generated by Dataprep.

4. What is an example of data preparation?

Consider an instance where you want to analyze e-commerce datasets containing sales, customer, product, and order data. You must first consolidate this data into a single dataset for data preparation. Clean this dataset by handling missing and duplicate values and correcting inconsistencies. You can then transform this data using processes such as aggregation and normalization.

Then, enrich this dataset by adding product ratings, customer segmentation, or competitor data. After this, validate it by checking for outliers and anomaly data records. This completes your data preparation process, giving you clean and consistent data for your e-commerce platform.

5. What is a test data preparation tool?

Test data preparation tools are software that generates and manages test data to check the performance of applications in development. They help identify and fix any discrepancies in software applications' data workflows.
