GOQL, a graphical query language for object-oriented database systems

In this paper, we present GOQL (Graphical Object Query Language). GOQL provides a user-friendly graphical interface to support ad-hoc queries for object-oriented database applications. Such queries are translated into standard OQL queries. In this paper, we illustrate the use and expressiveness of GOQL using an example, and briefly survey similar work and developments in the market and in the literature.
