Security Policies in Replicated and Autonomous Databaseste dependent optimizations..The paper uses previous models for object-based authorization, and extends them with policies to handle conflicts between local and global authorizations. It also discusses object migration and security administration. The problem of providing autonomy in a consistent way is discussed extensively.

The first algorithm performs the damage assessment and recovery simultaneously; whereas the second algorithm separates these two processes for improved efficiency. Both algorithms allow blind- writes on data items allowing damaged items to be recovered automatically.

Sacaddos: A Support Tool to Manage Multilevel Documents includes an intelligent document management tool to analyze the content of a document in order to derive which classification rules apply to this document. When several contradictory rules apply, SACADDOS suggests to solve the conflict by defining an order of preference between the contradictory rules.
