Abstract

Intelligent Networks are evolving as data-intensive multi-layer
information systems. Databases can be found within or associated with
various functional entities of the IN reference model. The aspects of
database distribution and heterogeneity are present both within the
functional entities and between them, in a real implementation. In
particular, the Service Data Function (SDF) has to be implemented in
such a way that two different physical entities: the Service Control
Point and the Service Management Point have access to the SDF. What
makes an IN system a different kind of a distributed and
heterogeneous information system is that correctness and reliability
requirements vary vastly among different physical entities and yet
transactions are supposed to span many physical entities (real
systems). A reference model of IN data management is proposed whereby
the full service lifecycle is addressed, including service creation,
deployment, provisioning and execution. Essential data management
requirements are presented. The needs of transaction processing is
presented from the point of view of service provisioning and
execution. A classification of transactions interacting with the SDF
is proposed, and a corresponding correctness criterion is suggested.
