Definitions

  • the invention relates to a method for data transmission between computers, in which data from a first computer is read out in a first data format, then converted into a second data format and read into a second computer.
  • the invention further relates to an arrangement for data transmission between a first and a second computer, which are at least indirectly connected to one another on the data side.
  • Computers are used to manage data in many areas of business, science and the community. Basically, software is used that builds up databases. These databases have a format in which the data is stored, which depends on the respective software.
  • the object of the invention is to enable data transfer between computers in such a way that data of a first data format can be converted into a second data format with little programming effort, without having to intervene in the data or program structure of the software used.
  • a first procedural solution to the problem is that in one learning step key values TW A of the keys, the actuation of which generates a screen display of the values to be transmitted on the first computer and time intervals TZ A between several key presses are stored in one file each.
  • the key values TW A are read out and passed with the associated time intervals TZ A to the keyboard input of the first computer.
  • the screen display data are then sent to the printer command data via a print screen function Printer output (LPT 1) of the first computer (1) passed.
  • LPT 1 print screen function Printer output
  • This printer command data is stored in a screen file in the control computer. After an analysis of the screen file for the data to be transmitted, this data is stored in a data file that can be read or converted by the second computer.
  • This method makes it possible to read out the data to be entered on the second computer taking over from any screen display mask of an unknown program with an unknown data structure.
  • This data is stored in the data file after the analysis of the screen data.
  • This data file can be read by the second computer or at least in such a format that it can be converted with a conventional conversion program into the data structure which can be understood by the receiving program on the second computer. This enables data to be transferred between two computers without having to intervene in the internal program or data structure.
  • a second procedural solution provides that in a learning step key values TW B of the keys, the actuation of which enables data input on the second computer and time intervals TZ B between several key presses are stored in one file each.
  • the data to be transmitted are read out of a data file and belong to the key values TW B and / or the time segments TZ B and, together with the key values TW B, are entered as key values in the second computer.
  • this method can be used to transfer data without entering the data. or to have to intervene in the program structure of the receiving second computer.
  • a combination between the first and the second process-side solution enables an off-line connection between the first and the second computer.
  • the data to be transferred from the first computer are made available in a data file for transfer by the second computer. There is no need to intervene in internal structures in either the first or the second computer.
  • a third procedural solution to the problem is that in a first learning step key values TW A of the keys, the actuation of which generates a screen display of the values to be transmitted on the first computer, and time intervals TZ A between several key presses are each stored in a file.

  • the data to be transmitted are determined from the screen file and associated with the key values TW B and / or the time segments TZ B and, together with the key values TW B, entered into the second computer (6) as key values.
  • the screen output and the keyboard are used as the interface between the two computers.
  • a precise knowledge of the different database programs and the data formats is not necessary and it is therefore not necessary to intervene in the program or data structure.
  • the method can not only be used to transfer data between Personal computers are used. It can also be used in computer networks or on mainframes, where mainframe terminals represent the first and second computers. Furthermore, the method can also be used for data transmission between computer networks and individual computers or in other combinations.
  • the key values TW B with the data to be entered are passed to the keyboard input of the second computer in the input step.
  • the program of the second computer is thus excited by the key values TW B and / or by the time intervals TZ B for readiness for data input. Because the data determined from the first computer are entered as key values at the keyboard input, a complete decoupling of the different program systems is achieved.
  • This method will take a considerably longer time than a data conversion via a program to be created separately. However, this method can be used universally and in many cases is easier to implement than the creation of a separate conversion program and the subsequent error-free execution of the data conversion. In addition, this form of • conversion can be followed precisely on the screen and can therefore also be traced or even programmed by a non-specialist.
  • an embodiment of the method according to the invention is characterized in that in the input step the key values TW B with the data to be input are given to an internal bus of a third computer and after the data transmission or a part thereof has been completed transferred data from the third computer into the second computer.
  • This embodiment of the method according to the invention has the advantage that the data is not input via a keyboard input, so that it can be carried out at a much higher speed. Due to the fact that the data are brought into the second computer from the third computer, it is possible for the second computer to carry out the data to be entered without any technical intervention.
  • the printer command data are additionally stored in the control computer as a control file.
  • a jump keyboard value is stored in the TW A file and / or in the TW B file, which is not a function on the first or second computer but a processing of the respective one TZ A or TZ B file triggers control commands contained.
  • the first control command triggers a print screen function and the second control command compares target data with the control file, as a result of which either the further control commands or the keyboard commands following the jump keyboard value are processed.
  • a method of this type can be used to check whether the screen page which is currently used for output or input actually corresponds to the desired screen page, as a result of which data transmission errors can be avoided. For example, it is possible to branch to the control command processing from the TZ A or TZ A file after the jump keyboard value.
  • the comparison command can be used to trigger a search, for example, for the desired word "main new" in the control file.

Abstract

L'invention concerne un procédé de transmission de données entre des ordinateurs, selon lequel des données d'un premier ordinateur sont extraites dans un premier format de données, puis converties en un second format de données et mises en mémoire dans un second ordinateur. L'invention concerne en outre un système de transmission de données entre un premier et un second ordinateur interconnectés au moins indirectement côté données. L'invention vise à permettre de transmettre des données entre des ordinateurs, de manière que les données d'un premier format de données puissent être converties en un second format de données sans nécessiter de programmes complexes, sans avoir pour autant à intervenir dans la structure de données ou de programmes du logiciel utilisé. Selon l'invention, il est prévu à cet effet d'activer, par l'intermédiaire du clavier d'un ordinateur de commande, le premier ordinateur en vue d'une sortie de données et le second ordinateur en vue d'une entrée de données, chacune de valeurs de touche TWA, TWB et chacune des valeurs temporelles TZA et TZB étant protocolée. Il est également prévu d'introduire les données à transmettre provenant des données d'écran du premier ordinateur dans le second ordinateur, par l'intermédiaire d'un programme d'allocation.
