Description: Harmonization is the process of ensuring that data from different sources is consistent and compatible. This process is fundamental in data management, as it allows for the integration of information from various databases, systems, and applications, ensuring that the data is coherent and useful for analysis and decision-making. Harmonization involves standardizing formats, eliminating duplicates, and resolving conflicts between data, which facilitates interoperability between systems. In a data environment, where data comes from multiple sources and in different formats, harmonization becomes a critical step to ensure data quality and integrity. Additionally, in the context of agile methodologies and behavior-driven development, data harmonization can be essential to validate that systems work correctly and that the data used in tests is representative and accurate. In summary, harmonization not only improves data quality but also optimizes analysis processes and decision-making in organizations.
