Database and method for building a database

摘要

Method for creating a database starting with files, each file comprising one or more records, each record related to a different identity and containing a series of first data items related to features of identity identifying subjects and second data items related to features of one or more other subjects. For each type of identity an identity table is created in which all first data items are stored avoiding double entries. All second data items are stored in a subject table also avoiding double entries. Each relation, describing which subject feature was retrieved from the same record as which identity, is stored in a relation table. <IMAGE>
