Model-based user interface development environments show promise for improving the productivity of user interface developers, and possibly for improving the quality of developed interfaces. However, model-based techniques have rarely been applied to the important area of database interfaces. This lack of experience with data intensive systems may have led to model-based projects failing to support certain requirements that are essential in data intensive applications, and has prevented database interface developers from benefiting from model-based techniques. This paper presents a model-based user interface development environment for objectdatabases, describing the models it supports, the relationships between these models, and the tool used to construct interfaces using the models.
On-Line Analytical Processing (OLAP) systems based on a multidimensional view of data have found widespread use in business applications and are being used increasingly in non-standard applications. These systems prov...

A metamodel definition presents some important issues in the construction of an object database management system, whose rich data model inevitably increases the metamodel complexity. The required features of an objec...

We describe the OLAP++ system for federating OLAP and objectdatabases. The system allows users to easily pose OLAP queries that reference external objectdatabases. This enables very flexible and fast integration of object data in OLAP systems without the need for prior physical integration.
The development of any comprehensive proposal for spatio-temporal databases involves significant extensions to many aspects of a non-spatio-temporal architecture. One aspect that has received less attention than most ...
