The term that describes an attribute's value that cannot be divided into multiple pieces of information is an atomic value. In database design, an atomic value refers to a singular, indivisible unit of data. This concept is crucial for ensuring that data adheres to normalization principles, where each piece of information is distinct and stored in its simplest form. Atomic values allow for efficient data retrieval, manipulation, and storage, making it easier to maintain database integrity.

In contrast, a composite value consists of multiple elements that can be broken down into smaller sub-values, which does not align with the definition of atomic values. Aggregate values typically represent a summary, such as a total or an average from multiple items, and complex values can contain multiple components but are not restricted to indivisible units. Thus, the uniqueness and clarity of atomic values are essential in creating streamlined and efficient database structures.
