A Graphical Navigator for Viewing Databases
A Research Article
Authors: Authors: Janak Mulani, Arun Bahulkar

This paper describes the architecture and implementation of Graphical Navigator, a system for visualizing and querying databases. The schema of a database is represented by classes and associations between the classes. Thus, a database is viewed as a labeled graph. A graphical query notation was developed to query databases. The query notation allows formulation of recursive and predicated queries. The system facilitates incremental querying by way of workspaces. The formulation, execution and incremental querying are all done in a highly interactive and visual environment.

A Programmable Analysis and Transformation Framework for Reverse Engineering
Authors: Ravindra Naik , Arun Bahulkar 

Reverse Engineering refers to understanding an existing software system, and documenting the understanding in a desired format. Depending upon the purpose, which can be problem diagnosis, impact analysis, functional enhancements, or re-engineering to newer technologies or newer design, the reverse engineering artifacts vary in their definition, the abstraction level, and contents. Current state of practice relies on pre-cast tools, which extract a set of pre-defined information, with little or no inputs from the analyst. We propose a specification-based approach that allows analyst to specify and control the contents and abstraction level of the reverse engineering artifacts, while allowing user-interaction during extraction.
