    • The invention concerns a method and device for presenting, managing and exploiting graphical queries in data management systems. In the method queries in data management systems may be handled graphically in a simple fashion to form a query formalism incorporating objects and their relationships, and including specialization relationships between types of objects. The method comprises defining in a graphical format a semantic model defining the structure of data within a database and using said semantic model to define a database query, the method being characterised in that the semantic model comprises a type graph comprising types of objects, and attributes and specializations linking types to one another to define relationships between said types. Applications considered include form-based applications and textual reports.
    • 本发明涉及用于在数据管理系统中呈现,管理和利用图形查询的方法和装置。 在方法中,数据管理系统中的查询可以以简单的方式以图形方式处理,以形成结合对象及其关系的查询形式,并且包括对象类型之间的专门化关系。 该方法包括以图形格式定义定义数据库内的数据结构的语义模型,并且使用所述语义模型来定义数据库查询,所述方法的特征在于所述语义模型包括包括对象类型和属性的类型图 以及将类型相互链接以定义所述类型之间的关系的专业化。 考虑的应用包括基于表单的应用程序和文本报告。
