different geographic regions. Many other high-Fault-Tolerant Systems (such as clustra [11]) also provide Fault-Tolerant capabilities through this replication, but they do not have the ability to execute in the same address space as the application system. Mnesia can be partially recovered from a disaster, and all objects written to the disk can be safely separated from garbage (objects are coded in such away that it is possible to safely disinguish data from garbage ). This makes it possible to

This is a written exercise with no specific solutions.Determine which applications, application servers, and databases are used by your environment. Then focus on the database and experience the size and busyness of the database. Consider the number of users, data volatile, and the amount of data.Finally consider how important they are to the organization: How much downtime is allowed for each application and database? How much data is allowed to be lost? Can I use quantitative analysis of finan
