What is used to designate each row location?

Each row location in a database or spreadsheet is typically designated by a unique identifier, often referred to as a "row ID" or "primary key." This identifier allows for easy retrieval and manipulation of the specific data associated with that row. In spreadsheets, rows are usually numbered sequentially (e.g., Row 1, Row 2), while in databases, rows may have custom identifiers that are unique across the dataset.
