What is a key aspect of a simple field in Avaloq?

A key aspect of a simple field in Avaloq is that it corresponds to a single value. This means that the field is designed to store just one piece of information, such as a numeric value, a string, or a date, making it straightforward and easy to manage. In contrast, other options involve characteristics that are not representative of simple fields. For instance, a field that can hold multiple values would indicate a more complex or structured data type, such as an array or collection, which is not the case for simple fields. Similarly, complex data handling or immutability pertains to different aspects of data manipulation and storage in programming and database management that do not apply to the concept of simple fields in Avaloq.
