OMS Java : Providing Information, Storage and Access Abstractions in an Object-Oriented Framework

In this paper, we present the main objectives and components of the OMS Java data management framework. We argue that developers of modern information systems require high-level application programming interfaces, storage platform independence and support for universal client access. We describe how the OMS Java framework provides three level of abstractions — storage, information and access in order to realise these objectives. We then present each of these layers in turn — starting with the information abstractions which lie at the core of the system and then going on to the storage and access layers
