A METHOD AND DEVICE FOR EXTRACTING DATA FROM A GROUP OF DATA

摘要

An electronic, computer based telecommunication system has an object oriented processor system with the aid of which data are exchanged between data bases and customers connected thereto. A data record is created from a selected memory in which all the information from for example a telephone call is stored, this record being common to all customers. The record comprises only that information which is required by the customers. From this data record then the specific data which are desired are extracted . Three kinds of objects are defined and stored in corresponding memories, service templates, customer templates and an output type. The first objects define the types of service which is used. In a second object the information is defined which a customer wants to extract from the common data record. Thus each customer has its own customer template. In the third object, the output type a union is created, based on the information in the other objects, the service templates and customer templates, the union being used for pointing to that information from the memory, which forms the common data record. Identical copies of the common data record are stored in memories specific for each customer for extraction by postprocessing units.
