摘要: ion Level Incompatibility – Entity and attribute level differences that arise because two semantically similar entities or attributes are represented at different levels of abstraction Generalization conflicts Semantically generalization in Web services service 1 2 GRAD-STUDENT (ID, STUDENT(ID, Name, Major) Major, Type) * WS2 defines the student entity a much general level. A mapping from WS1 to requires adding Type element with default ‘Graduate’ value, while other direction is partial function. Aggregation PROFESSOR FACULTY Dept) ProfID, set-of Professor Faculty entity. When output entity, it possible identify group belongs to, but generating not possible. Attribute modeled as an one COURSE Semester) DEPT( Course, Sem, .., ..) Course by WS2. With definition contexts, mappings can be specified both directions. Heterogeneities / Conflicts Examples conflicted elements shown color Suggestions Issues Resolving Matching & Mapping
