DESCRIPTION :
This Master 2 internship is in the context of IPCEI-CIS (Important Project of Common European Interest - Next Generation Cloud Infrastructure and Services) DXP (Data Exchange Platform) project involving Amadeus and three Inria research teams (Loreley, CEDAR and MAGELLAN). This project aims to design and develop an open-source management solution for a federated and distributed data exchange platform (DXP), operating in an open, scalable, and massively distributed environment (cloud-edge continuum).
The internship will be located at The Inria Center of the University of Lorraine in the Loreley team. It will be supervised by Claudia-Lavinia Ignat, Research Director at Inria in Nancy and Stefania Dumbrava, Assistant Professor at ENSIIE/Inria Paris/Télécom Sud-Paris., [Budiu22] Mihai Budiu, Frank McSherry, Leonid Ryzhyk, Val Tannen: DBSP: Automatic Incremental View Maintenance for Rich Query Languages. arXiv:2203.16684, 2022.

Principales activités
The project will focus on a collaborative data management scenario based on a graph-relational model, in which a graph view is defined over a set of relational tables, together with a set of basic integrity constraints, and replicated across multiple sites. The intern will help define an abstract replication model that treats such views as the primary unit of synchronization between a small number of replicas. This model will describe how a restricted class of updates is propagated and reconciled under concurrency, and under which assumptions basic constraints are preserved or can be restored after conflicts. Building on this model, the intern will design and implement a lightweight prototype on top of an existing data management system. This prototype will simulate several replicas, apply simple but well-specified replication and merge policies, and maintain materialized graph views in the presence of updates.
