Abstract

We consider concurrency control issues in a Mobile Data Access System (MDAS), which is distributed heterogeneous database system with clients working in a mobile environment. Taking into consideration the formal model described in previous works, we propose a concurrency control protocol for an MDAS which includes both database management systems providing local serializability and those using Snapshot Isolation. We also consider the possibilities of using the results in aviation and space industry.
