The database approach emphasizes the integration & sharing of data throughout the organization. Terrorism & Crime. Control of data redundancy The database approach attempts to eliminate the redundancy by integrating the file. A. Redundancy is the concept of repetition of data i.e. each data may have more than a single copy. The file system cannot control redundancy of data as each user defines and maintains the needed files for a specific application to run. There may be a possibility that two users are maintaining same files data for different applications. Data redundancy and inconsistency. on clearing the database from unused data and to increase the data consistency by reducing the data redundancy. Due to Duplicate data , duplicate information gets stored in the database and thus cost for storage and retrieval increases. 5. Data compression is achieved when one or more of these redundancies are reduced or eliminated. Data redundancy results in memory wastage. Data redundancy does not have specific advantages. You can edit the illustrations, resize the icons, and mold other deck elements without technical expertise. Other disadvantages include the likelihood of inconsistency of data as well as decreased efficiency of a database. D. High Cost. A.
