In platform software testing, these checks must be performed across different database platforms and network configurations to ensure that relationships are maintained correctly even under stress or network interruptions. Violations of referential integrity can lead to inaccurate data, failed transactions, and application instability.
-
Checksum and Hash Verification
Checksums and hash functions are used to detect data corruption during transmission or storage. By calculating a unique value based on the data’s content, checksums and hashes can be used to verify data integrity after it has been transferred or stored. For example, when transferring a file over a network, a checksum can be calculated at the source and compared to the checksum calculated at the destination. If the checksums match, the data is considered to be intact. In platform software testing, these verification methods must be applied across different file systems, network protocols, and storage devices to ensure that data remains uncorrupted during storage and transfer. Mismatched checksums indicate data corruption and require corrective action.
-
Data Consistency Audits
Data consistency audits involve periodic checks of data across multiple systems or databases to ensure that the data remains synchronized and consistent.
