Definitions
- the present invention relates to a network for data transmission between applications with proprietary interfaces, in which the applications can be coupled via a data broker for data transmission, the data transmission by means of requests and responses via the data broker is feasible and the requests / responses are designed as XML messages.
- the present invention is in the field of information and communication technology. Due to the very diverse requirements in this technology, computers and associated applications from various manufacturers have to be networked in integrated systems.
- the OMG body has specified the CORBA architecture, which can be used to communicate the various applications, also known as applications.
- So-called CORBA applications consist of one or more objects which represent an image of one or more real processes - a function and associated data. Each object is assigned a type. There are usually several instances of an object.
- An e-commerce web application consists of those instances which correspond to the shopping cart of the current users or customers of this web application.
- For the specification of the architecture CORBA reference is made to document [1].
- an interface partition is necessary.
- the applications have interfaces based on CORBA specifications, which are defined in the CORBA IDL (Interface Definition Language) and then translated and implemented in the various implementation languages of the target systems.
- CORBA IDL Interface Definition Language
- the invention is therefore an object of the invention to provide a network that allows in particular for the integration of new applications, particularly easy to initialize the later intended function of the application required data traffic and subsequently perform in everyday operation of the network.
- this object is achieved by a network for data transmission between applications with proprietary interfaces, in which the data broker has an application-specific application adapter for each of the applications coupling to it, wherein each application adapter comprises an XML en / decoding unit, a generic interface and a notification interface ,
- the generic interface takes over the administration of the application with regard to the required and / or delivered user data in the network.
- the notification interface ensures that relevant data for this application are made available to other applications embedded in the network or are obtained from the rest of the application.
- the data required for an application and / or the data supplied by an application can be packed into an XML format and / or extracted from an XML format by means of the XML En / Decoding unit.
- the XML format is a framework within which any user data from different applications can be transported through the network.
- a central name management service can be provided, in which the associated application logs on by means of its generic interface.
- the generic interface can be designed such that it stores the names of the data which are required by this application and / or can be delivered to the central name management service.
- the notification interface can be used in a targeted manner to subscribe to an application in a central notification service To register data and / or as a supplier of certain data. This also ensures a clean separation between the information to be provided to the name management service and the actual retrieval or provision of data, which in particular simplifies the integration of new applications into the network as well as the modification of the data requirements of existing applications.
- a data change message can be sent to all the notification interfaces for which the associated application is registered as a subscriber of this data in the central notification service.
- the notification interface can be configured such that in the case of a data change in an application (possibly also by a data input originating from another application) an update message is sent to the central notification service.
- the notification interface can be designed such that a demand for certain data currently required by an application can be sent to the central notification service. In this way, an application can independently determine and schedule the data it subscribes to.
- FIG. 1 shows an overview of the arrangement of different applications exchanging data via a CORBA-based data broker
- FIG. 2 shows a communication network operating according to the arrangement according to FIG. 1 with a first example for the function of the application adapter
- FIG. 3 shows a communication network operating according to the arrangement according to FIG. 1 with a second example for the function of the application adapter.
- FIG. 1 shows an overview of the arrangement of various applications which exchange data via a CORBA-based data broker 1.
- the data broker is designed as a CORBA / ORB data broker.
- Reference numeral 10 denotes so-called peripheral systems.
- the individual applications 101, 102, 103, 104, etc. represent, for example, a weather data evaluation system, a communication system for the acquisition of ground pressure and temperature data, etc.
- the surrounding systems 10 are the necessary subsystems and thus serve the support of the weather service. System to be fulfilled task.
- the reference numeral 20 denotes so-called engagement systems.
- the individual intervention systems 201, 202 stand, for example, for the control of the use of mobile weather stations, such as rising weather balloons, as well as the general control of automatic weather stations. From the application, the aforementioned two engagement systems 201, 202 are accessible via a portal 29.
- Auxiliary systems 30 include, for example, a notification service 301, a workflow engine 302, a name service, and so forth.
- peripheral systems 10 and intervention systems 20 are not located in one place, but are generally located over a region, e.g. a country, distributed.
- the data core 1 is subdivided by so-called data guards 2.
- These dataguards 2 have the function of a firewall. This is to be distinguished from an encryption, which is described below.
- the data associated with the weather service system is kept in a relational database 27; Access and administration take place via a data manager 28.
- peripheral systems 10 and the engagement systems 20 usually represent a rather complex network, within which on the one hand the applications 101 to 104, 201, 202 are subject to more or less constant changes and on the other completely new applications or
- application adapters 50 (FIG. 2) are provided, which on account of their construction make it possible to provide these adaptation functions mentioned above particularly simply and with only little effort.
- the application adapters 50 all have the same structure, which essentially comprises an XML En / Decoding XML, a generic interface GI and a notification interface NI.
- the XML En / Decoding XML ensures that the user data required for the application and / or the user data supplied by the application are transported in an XML frame by the Data Broker 1.
- the function of the generic interface GI and the notification interface NI can best be explained by means of the work flow a) to i).
- a data bus 1 ' is additionally provided, which is still used, for example, due to an older connection of the applications 102 and 103 to a data exchange of these two applications.
- the application 202 now experiences, for example, a reprogramming and now requires more specific new data that this application has not previously received.
- the notification interface NI of the application 202 logs in as an interested party for this data at a notification service NoS arranged in a network service NwS.
- the application 102 notifies in a step b) a data change over the data bus 1 'to the application 103.
- the changed data are written in a step c) in a local database of the application 103, that is updated there.
- the application adapter 50 of the application 103 then takes in a step d) the Updated this data by, for example, by means of database trigger or by monitoring the events on the local database of the application 103 has followed.
- the updated data now packed in XML format are now sent by the application adapter 50 using its generic interface Gl in a step e) to the generic interface GI of the application adapter 50 of the file manager 28, which in step f) with an update of the central database 27 results.
- FIG. 3 shows an example of a functional sequence from the point of view of the application 103 with the steps a) to g) in a schematic representation.
- the application 103 logs in according to step a) using their notification interface NI as an interested party for certain data of the application 202 in the notification service NoS.
- a transmission of updated data takes place, which in step c) results in an update of the central database 27.
- the generic interfaces GI are responsible, which provide or receive the data packed in the XML frame.
- step d) the notification interface NI notifies the updating of this data to the notification service NoS, which in the Step e) ua also informed the application 103 on its notification interface Nl about the data update. Accordingly, the bidirectional arrow in step f) symbolizes the retrieval and delivery of the updated data via the respective generic interfaces GI. Finally, in step f), after the XML decoding has taken place, the data is updated on a local database of the application 103.
- This example also shows, due to the clear structure of the application adapter 50, in which simple way data can be exchanged within the communication network shown.
- the simple structure of generic interface so the operational sending and / or In particular, obtaining data and messaging interface, that is, operationally communicating what data is needed or delivered, makes it possible to accomplish the incorporation of new applications in a simple and cost-effective manner.
