A method of extracting data from one or more data sources and loading the data into one or more destinations sources is disclosed. The method can include deploying data engines into one or more user network systems, receiving input with respect to a first data source, receiving input with respect to a second data destination, and receiving input with respect to one or more user-defined data stored on the first data source. The method can further include receiving input with respect to linking the first data source and second data destination to the deployed data engines and pinging, via data engines, for requests to extract and direct the user-defined data from the first data source, and retrieving, via the data engines, the user-defined data from the first data source and storing the retrieved user-defined within an intermediary database to be loaded it into the second data destination.
