Various examples are directed to systems and methods for operating an application for use with an enterprise database system. A common format process may receive, from a user device, a first request directed to the enterprise database system, convert the first request into a common protocol, and send a first common protocol request to the application logic code. The application logic code may generate a second request in the common protocol and send the second request to the common format process. The common format process may convert the second request from the common protocol to a database query protocol to generate at least one database query and send the at least one database query to the enterprise database system.
