Abstract
The problem of representing and processing inaccurate data is the subject of the study in [31, 32, 33, 34, 35]. The approach used was not only to keep tack of information, but also to keep track of sources confirming a piece of data along with the data and use that additional information in all data manipulation activities. In particular, the information about the source is used to query data. To this end, author had extended the relational algebra operators and used those extended operators to produce the answer to the query as well as the information regarding the sources contributed to the answers to the query.
