This document describes the work done in the UNU/IIST MoFIT project during the period April--September 1996 by five Fellows from Vietnam (four from the Ministry of Finance, one from the Institute of Information Technology). The eventual aim of the project is to describe a complete financial information system. The first part of the project concentrated on the taxation system, the Vietnamese Government's main revenue collecting system. It includes a domain analysis in two parts, an informal narrative and a formal model; a prototype of part of that system developed from the formal specification and used to test it; a description of the security aspects of the system; an extension of the formal model describing the security aspects; and a description of taxation policies, particularly those likely to change in the immediate future. The formal components are written in the RAISE specification language, RSL using the RAISE development method.
In this document we continue the work started in ``Developing a Financial Information System'', UNU/IIST Research Report 81. That document concentrated on the taxation system and on its detailed development. Here we take a broader view, sketching the taxation system and also the budget, treasury and external aid and loan systems. Then we show how these may all be combined, allowing not only ``vertical'' communication within each system but also ``horizontal'' communication between components of different systems. We thus provide a top-level specification of a national financial information system.
