Method for visualizing path expression on the object-relational database management system

摘要

The invention object relates to the visualization method of the path expression in relation DBMS.; A method for visualizing the path expression by using a system including a database managed by the related DBMS, - the present invention and GQL system for the client, the graphical query system and a networked objects - the relation DBMS, the object If the client selects one class among the classes of the database represents the attributes for the selected class to the first class box, the client is a domain class, specify if you select one of the attributes of a first class box selected properties as a domain class It indicates attributes of the class to the second box. And, if the client selects one of the properties of the new class appears another box shows the domain class of the property to a third class box shows a list of attributes for the properties of the domain class in the box. A client would be to create a query condition for the attribute using the class box appears after represents the path expression for a graphical query as class box, GQL system changes the query conditions created by the client in a text query is transmitted to the ORDBMS.
