2. Cleansing and refining: This is where the data is purged of obvious errors that shouldn’t make it into the final data package.

3. Distillation and Blending: This is the phase where commonly substituted terms and duplicated entries are taken into account, so they don’t cause abnormalities in the final data set. Distillation may involve applying custom data quality rules using automation.

4. Documentation: Documentation is important in case other parties use the same data for new projects in the future. Metadata in the data catalog can include details on relationships between databases, definitions for technical and business terminology, source information, and a list of changes to the data during distillation and when they were implemented.

5. Reformatting and Packaging: This step is important because companies may use any number of tools and procedures for interacting with the data after it’s been discovered. The resulting data package should be ready for importation into other tools for visualization and further manipulation.
