A placeholder for data is a variable or symbol that temporarily represents a value or piece of information that is not yet known or available. It is often used in programming, databases, and templates to indicate where data will be inserted later. Common examples include "X" in mathematical equations or "NULL" in databases. Placeholders help maintain structure and function while waiting for actual data to be provided.
