Standardizing data formats is crucial to ensuring uniformity across the dataset after data conflicts have been eliminated. Dates may be structured differently in one data set than another, for instance. Data analysts should make sure that all data is kept across all data sets in the same format, such as YYYY/MM/DD or MM/DD/YYYY.

Step 4: Consolidate data sets

Different data sets may be integrated into a single data set, unless banned by data protection laws. This frequently calls for dismantling dataset silos and bringing them together. Whether they are utilizing or considering a data lake, data warehouse, or data lakehouse, many enterprises rely on evolving data architectures to accomplish their goals. Data set consolidation increases the effectiveness of data analysis by reducing data duplication and streamlining the data processing procedure.

Step 5: Verify the data’s integrity.
