What technique could be utilized to ensure data is only pulled for active members in the families schema?

Setting the Family ID as a primary identity is critical for ensuring that data is accurately associated with active members in the families schema. When the Family ID is designated as a primary identity, it facilitates a direct link between the family data and active member records, allowing the system to effectively filter and retrieve only the necessary data for members who are currently active.

This approach leverages the structure of the schema, ensuring that data queries are focused on those members associated with the specific Family ID in question. By establishing the Family ID in this manner, you can streamline data management and enhance the efficiency of data retrieval processes, targeting only relevant and active members.

The other options do not effectively address the requirement of filtering data for active members. Utilizing archived data could lead to decisions based on outdated information. Limiting access based on roles is more about controlling who can see the data, rather than ensuring only active data is retrieved. Periodic queries can capture data changes, but they do not inherently guarantee that only active members' data is being queried unless specifically designed to do so.
