Abstract:
A process for transmitting data between a central unit for processing, storing and providing data and a data terminal device, wherein application related queries (query functionalities) having a specific query structure corresponding to a given application are directed from the data terminal device to the central unit where they are stored, and wherein responses of the central unit are transmitted to the data terminal device with a specific response structure corresponding to the given application, the process comprising the steps of:initially storing a permanently unchanged application-independent query structure (general query structure) and a small number of application independent response formats in both the central unit and the data terminal device; providing at least two specific response structures; defining, for each application, the specific query structure on the basis of the application-independent query structure; storing the defined specific query structure in the central unit in the form of a parameter set; requesting, as needed, a specific query structure not yet stored in the data terminal device from the central unit via a communication channel; receiving and storing, at me terminal device, a parameter set transmitted from the central unit corresponding to the requested specific query structure, and displaying the specific query structure to the user in the data terminal device in the form of an input mask for receiving entry of at least some of the parameters of a query; implementing a query functionality by forming the applicable specific query structure in the data terminal device from the application-independent query structure on the basis of the received and stored applicable parameter set; transmitting the applicable specific query structure to the central unit after it has been at least partially filed out with values by the user; and making available to the user, at the data terminal device, responses transmitted from the central unit based on one of the stored response formats designated in the particular response.
