PHN 9831 11.3.81 ABSTRACT: Device for associative searching in a sequential data stream composed of data records. A device is described for the processing of a data base consisting of a sequence of data records. There are provided a reference memory (140) for a reference data record and a mask memory (142) for a mask data record. In reaction to the successively received data of a data record, these memories can be read in order to activate a comparison. There is provided an indicator element (160) which has a state "provisionally correct" and which is activated by a starting signal produced by the recep- tion of a data record. If the comparison indicates that an impermissible relationship exists between the content of an element of the data record received and the corres- ponding element of the reference data record, the indica- tor element is set to the state "incorrect". The data re- cord received is meanwhile stored in a data buffer (100, 102). At the end of the reception, the state of the indi- cator element indicates whether or not the data record may be applied to a user. The data buffer may consist of two buffer sections, each for one complete data record, which alternately operate in a read mode and a write mode.
