Abstract
Unlike class-based models, such as the relational model and object-oriented models, the instance-based data model (IBDM) [1] separates data stored about individual things (instances) from how those instances are classified, resulting in a ‘two-layered’ approach (instance and class layers). In this poster and system demonstration, we illustrate the use of iQL (instance-based query language) for the IBDM. This language supports unique query capabilities that exploit the separation of data about instances from their classification. The tool has been implemented in conjunction with a prototype DBMS to support the IBDM [2].
