An Indian company's finance MIS shows month-end figures that differ from the sales MIS because sales data is entered manually in two separate spreadsheets by different teams. A director also notes that an employee altered sales figures before the report went to the board. Which combination of measures best addresses both problems?

An integrated database with one source of data, combined with audit trails and access controls, is best. It removes inconsistency from duplicate entry and records or restricts who changes figures. Encrypting the final report or manual reconciliation does not prevent alteration earlier in the process.

Explanation

Inconsistency comes from duplicated data entry, solved by an integrated single source of data. Tampering is addressed by audit trails and access controls that record and restrict changes, which also helps evidence under electronic records law. Encrypting the final PDF does not stop earlier alteration, and manual reconciliation leaves both weaknesses.
