Abstract
The document is a complete user manual for
the object-oriented database management system ODRA (Object
Database for Rapid Application development), including its Virtual
Repository Management System (VRMS). VRMS allows for virtual integration of
distributed, heterogeneous, redundant and fragmented data and service
resources into a centralized, homogeneous, non-redundant and non-fragmented
whole. The specification includes installation and administration manual,
general architecture of the software, integrated development environment,
description of an object-oriented data model, specification of database query
and programming language SBQL (Stack-Based Query Language), virtual
updateable views, sessions and transactions, a client-server protocol, and
various front end and back end interoperability facilities implemented for
ODRA.
