What data type is the DurableKey expected to be in Caboodle?

The DurableKey in Caboodle is expected to be a String data type. This design choice is made primarily for the purpose of ensuring uniqueness and consistency across various datasets. Strings allow for a broader range of identifiers, including alphanumeric characters, which can be essential for accommodating a variety of key formats.

Using a String for DurableKey also supports easier integration with different systems and data sources that might use different identifier formats. This flexibility is crucial in a healthcare data environment, where unique keys might be derived from multiple sources, such as patient identifiers, system-generated keys, or other alphanumeric codes that might not fit into strict numeric formats.

In contrast, using other data types like Integer, Float, or Boolean would impose constraints that could potentially limit the compatibility and robustness of the DurableKey, making it less effective in the broader context of data management within Caboodle.
