XML becomes a de facto standard for representing andexchanging data over the Web. With the tremendous growthof XML data on the Internet, an efficient database systembecomes necessary to maintain it. Traditional databasesthat force all data to conform to an explicitly specified rigidschema are inefficient to maintain irregular XML data, thus,new data models, called native XML database management systems, are introduced. Currently proposed nativedatabase systems mainly focus on designing database architectures and its components, but they have not addressedhow an efficient user interface can be designed to supportusers to interact with their databases.In this paper, we mainly present the design and implementation of DB manager, a visual interface for the native XML database management system, NextDB. DB manager is an integrated interface which is composed of various components that provide interactive communication between external users and internal database. It offers a richvariety of functions, and provides usability and accessibilityto users. The results from initial usability study show thatthe visual interface is usable and efficient for most users.
