To ensure data integrity, which practice should be followed when creating schemas in AEP?

Using standardized naming conventions when creating schemas in Adobe Experience Platform (AEP) is crucial for ensuring data integrity. Standardized naming conventions help in maintaining consistency across schemas, making it easier for teams to understand the purpose and meaning of various fields. This practice reduces the likelihood of errors in data entry and integration, as all stakeholders can easily recognize and utilize the attributes.

Additionally, having a consistent naming strategy aids in identifying potential issues and enhances the overall readability of the data structure. It also facilitates data governance, as clear and recognizable schema names can help in tracking data lineage and ownership. As organizations scale and data usage increases, such standardization becomes essential for effective data management and quality assurance.

While the other options may address aspects of data management, they do not specifically contribute to the integrity of the schema in the same way that standardized naming conventions do. Limiting fields might restrict necessary data, keeping attributes optional could lead to inconsistent data collection, and condensing schemas may compromise clarity and usability. Thus, standardized naming conventions stand out as the best practice for maintaining data integrity in AEP schemas.
