//todo: check the enum values before entering & changing in the database.
//todo: change asserts for dynamic boundary checks into failure answers.#
//todo: check autoincrement boundary and set to 16bit limits
//todo: If the sink is part of a gateway, the listconnectionFormats is copied to the gatewayInformation. Check this statement for sinks & sources
//todo: exchange last_insert_row id to be more safe
//todo: create test to ensure uniqueness of names throughout the database
