PROBLEM TO BE SOLVED: To provide a method, system and product for managing the relation in a data abstraction model abstractively describing data in a database. SOLUTION: One embodiment of the present invention provides a method for linking logic branches of data in the database based on this relation. This method comprises accessing the data abstraction model abstractively describing the data in the database. The data abstraction model determines a logic tree structure having a plurality of logic branches. Relation between logic fields of different logic branches is specified, and a logic link abstractively describing the specified relation is generated. COPYRIGHT: (C)2006,JPO&NCIPI
