We can assume that two or more operations cannot be executed simultaneously by the database server
. Because of this assumption, and in accordance with the analogous assumptions that have been made in a number of works on the restoration of databases (Kumar, 2001; Gelenbe and Derochette, 1979) that arise in the course of requests' servicing, we can assume that failures and moments of queries in the database take place in accordance with the laws of Poisson.

The major difficulty was not in displaying the Microsoft Access meta-data but in transferring the files from the central database server

An open source database server
has nor been an option for enterprise solutions.
To ensure that students and faculty using the system work uninterrupted in the event of planned or unplanned server outages, Vista 1.0 adds session failover and facilitates database server
