A fusion algorithm for joins based on collections in Odra-Object Database for Rapid Application development
In this paper we present the functionality of a currently under
development database programming methodology called ODRA
(Object Database for Rapid Application development) which
works fully on the object oriented principles.
The database programming language is called SBQL (Stack
based query language).
We discuss some concepts in ODRA for e.g. the working of
ODRA, how ODRA runtime environment operates, the
interoperability of ODRA with .net and java .A view of ODRA’s
working with web services and xml. Currently the stages under
development in ODRA are query optimization. So we present the
prior work that is done in ODRA related to Query optimization
and we also present a new fusion algorithm of how ODRA can
deal with joins based on collections like set, lists, and arrays for
query optimization.
Keywords: ODRA environment, query optimization, SBQL, Object oriented databases, Collections in OOD
