What legislative act established government-wide financial data standards to enhance transparency?

The DATA Act of 2014 significantly enhanced the transparency of government financial data by establishing government-wide financial data standards. Its primary objective was to improve the availability, accuracy, and reliability of federal spending information. By mandating that federal agencies report their financial information in a consistent format, the DATA Act sought to make government spending more transparent and accessible to the public.

This act requires the creation of a centralized source for federal spending information, thereby allowing taxpayers and stakeholders to easily track and understand how federal funds are being used. The standards established by the DATA Act enable better integration of financial data across agencies, which improves oversight, accountability, and decision-making within the government.

The other acts mentioned focus on different aspects of government accountability and transparency, but the DATA Act specifically addresses the establishment of financial data standards, making it the correct choice for this question.
