Method and computer system for storing multiple attribute values

摘要

Method and computer system for storing data in a memory using a data structure with at least one instance of a first data type being associated with nodes of a second data type (InfoType) representing data attributes, and nodes of a third data type (InfoCourse) representing data records, associated with said InfoType nodes. The InfoType nodes are arranged in a first tree structure (110). The nodes of an InfoCourse (121) are arranged in a second tree structure (120). A multiple value structure (130) is superposed to the first tree structure (110) linking InfoType nodes (111, 112, 113, 114) of the first tree structure (110) that belong to one InfoCourse node (121) of the second tree structure (120).
