Abstract: Embodiments of the present invention provide a system for provisioning validated sanitized data for application development. The system is configured for establishing a communication link with a plurality of disparate systems, retrieving data from the plurality of disparate systems via the communication link, sanitizing the data retrieved from the plurality of disparate systems, generating a query to validate the sanitized data, wherein the generation of the query is based on a set of rules, validating the sanitized data using the query generated based on the set of rules, determining that the validation of the sanitized data is successful, and transmitting the validated sanitized data to a second plurality of disparate systems.
