Definition

AMOSQL [2] is a functional language having its roots in the functional query languages OSQL [1] and DAPLEX [5] with extensions of mediation primitives, multi-directional foreign functions, late binding, active rules, etc. Queries are specified using the select–from–where construct as in SQL. Furthermore, AMOSQL has aggregation operators, nested subqueries, disjunctive queries, quantifiers, and is relationally complete.

AMOSQL is a functional query language operating within the environment of Amos II , which is an open, light-weight, and extensible database management system (DBMS) with a functional data model. Each Amos II server contains all the traditional database facilities, such as a storage manager, a recovery manager, a transaction manager, and a query language. The system can be used as a single-user database or as a multi-user server to applications and to other Amos II peers. It has mainly been used for experiments with Mediators [4].
