Method for Merging Two Datasets in Data Analysis

How to Merge Two Datasets in Data Analysis

When merging two datasets in data analysis, the following approach can be taken:

  1. Identify common key columns in both datasets.
  2. Use a merge function to join the datasets based on the common key columns.
  3. Write the matching records to a new dataset.
  4. Write the non-matching records from the left-most dataset to a second dataset.
  5. Write the non-matching records from the right-most dataset to a third dataset.

By following this method, you can efficiently merge datasets in data analysis and handle matching and non-matching records effectively.
