Abstract
Verso is a database management system developed at INRIA. The main characteristics of the system are the following: • on-the-fly filtering is used for both unary (selection, projection), binary operations, and for updates. The filter is realized by a finite state automaton-like device. • data is organized hierarchically to take advantage of the power of the filter. • the user interface is based on a non-first-normal-form relational model. An algebraic language, and a screen interface are proposed. This three aspects are closely tied. They form the basis for the originality and the performance of the Verso database system. The version of the system discussed in the present paper has been implemented in Pascal and C under Unix on an SM90 computer. Performance studies are briefly mentioned.
