Data redundancy and inconsistency « Visicomp Codder
The main difference between data redundancy and data inconsistency is that data redundancy is a condition that occurs when the same piece of data exists in multiple places in the database whereas data inconsistency is a condition that occurs when the same data …... Redundancy of data is an inefficient and costly waste of resources. IT technicians, if given the opportunity to use their skills and intelligence, can eliminate or at least minimize this redundancy.

Data redundancy and inconsistency, Lack of data integration, inconsistent data definitions, data dependence. 5. Following the file processing model of data management, what three architectures emerged for integrated databases?... Data redundancy means youre checking for duplication. In order to make that check, you need to determine what signifies a duplicate within the table to which you are referring. There is not a single query that will satisfy until you can define what makes a duplicate record.

- Data Redundancy . A database term. Data redundancy in a database means that the same data is present in more than one table. Or in the case of a flat file database, there are records with partly duplicated data.
- Redundancy is a system design in which a component is duplicated so if it fails there will be a backup. Redundancy has a negative connotation when the duplication is unnecessary or …

Classification of data quality problems in data sources 2.1 Single-source problems The data quality of a source largely depends on the degree to which it is governed by schema and integrity constraints controlling permissable data values. For sources without schema, such as files, there are few restrictions on what data can be
