This is more like a dictionary entry. I'd expect to find an explanation of the term and its implications at data integrity, data cleansing, etc.
In computer science, transaction systems, dirty data is defined like this:
Consistency. Referring to its correctness, this property deals with maintaining consistent data in a database system. Consistency falls under the subject of concurrency control. For example, "dirty data" is data that has been modified by a transaction that has not yet committed. Thus, the job of concurrency control is to be able to disallow transactions from reading or updating "dirty data." [1]
