Abstract:
Systems and methods of accessing a database associated with a process control system send a request for information from a client application to an intermediate data server process and determine if the information is stored within a data source associated with the intermediate data server process. The systems and methods also send a request for the information from the intermediate data server process to another process if the information is not stored within the data source and access the database to retrieve the information subsequent to the other process receiving the request for the information.
