What database feature ensures that all compliance regulations are followed during a transaction?

The correct choice is regulatory compliance, as it is the specific feature of a database that actively monitors and ensures adherence to legal standards and compliance regulations throughout the transaction process. In real estate, compliance regulations can include anything from fair housing laws and environmental regulations to state-specific real estate laws. Incorporating a regulatory compliance feature helps ensure that all parties involved in a transaction follow these guidelines, thus minimizing legal risks and promoting ethical practices.

The other options serve different functions within real estate processes. Client tracking focuses on managing client relationships and communications, but does not necessarily ensure compliance with regulations. Financial forecasting pertains to predicting future financial performance and trends, which is crucial for business planning but is unrelated to compliance. Transaction history provides a record of past transactions and activities but does not inherently ensure that such transactions were in line with compliance regulations. Each of these features brings value to a real estate operation but regulatory compliance is the key to adhering to legal requirements during transactions.
