DATA PROCESSING
NUMBER FOUR
(4ai)
[PICK ANY ONE]
(i) Fragmentation refers to dividing a database into smaller pieces WHILE replication involves creating multiple copies of data to be stored on different servers.
(ii) Fragmentation is done to improve performance by reducing the amount of data that needs to be accessed WHILE replication is done to improve availability and reliability of data by creating redundant copies.
(iii) Fragmentation involves storing data in different locations WHILE replication involves storing copies of data in the same or different locations.
(iv) Fragmentation can lead to inconsistent data due to the distribution of data WHILE replication ensures consistent data by keeping copies up-to-date.
(v) Fragmentation can introduce complexity in managing data WHILE replication simplifies data management by allowing for easy backups and fail over.
(vi) Fragmentation can reduce network usage by reducing the data that needs to be transferred WHILE replication can increase network usage by creating redundant copies of data.
(4aii)
[PICK ANY TWO]
(i) Higher storage requirements: Creating multiple copies of data requires more storage space which can be expensive and inefficient.
(ii) Increased complexity: Managing multiple copies of data introduces complexity which can make it difficult to maintain consistency and accuracy of data.
(iii) Synchronization issues: Replication can introduce synchronization issues if multiple copies of data are updated at the same time leading to inconsistent data.
(iv) Network congestion: Replication can lead to increased network congestion if large amounts of data need to be transferred between servers.
(v) Security issues: Replication can introduce security vulnerabilities if copies of data are not properly secured leading to data breaches or loss.
(vi) Maintenance overhead: Managing multiple copies of data requires additional maintenance overhead including backups and updates which can be time-consuming and costly.
