A computerized method for managing data performed in a computer system. The data is stored in a data base including flat lines. Each of the flat lines includes values of the data and tags associated with the values forming tag-value pairs. The flat lines are scanned and an object of a class is created. The class specifies a subset including one or more tags selected from the tags of the flat lines. The flat line points to the object if a portion of the tag-value pairs of the flat line includes all the tags of the subset. When the flat line contains multiple alternative ways, through the subset(s) of tags or through different tag-value pairs, of pointing to the object of the class, then the object as individually identified by the alternative ways is taken to be the same object.
