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]

Hi. The definition given in this article appears to describe the term "dirty data" as some poor quality data. There is, though, another, very specific technical meaning for this term in ORM/databases context: "dirty data" refers to a state of an object that was modified in the application, but the modification was not flushed to the database yet - this definition does not have anything to do with the quality of the data, it describes its stage in the application lifecycle. The very first statement in this article appears very misleading, as it specifically puts an accent on the fact that this term is primarily used "in a computer system or database".
