In a computer system, a document ID is a unique identifier that is assigned to a document. This ID can be used to uniquely identify and retrieve the document within the system. Document IDs are often used in databases and other types of document management systems to ensure that each document is uniquely identified and can be easily accessed.
Document IDs can be assigned in a variety of ways. For example, they can be generated automatically by the system, or they can be assigned manually by a user. They can also be based on the content of the document itself, such as the title or a summary of the document.
In addition to being used for document management purposes, document IDs can also be used for other purposes, such as tracking changes to a document or for security purposes. For example, a document ID could be used to ensure that only authorized users are able to access a document.
