Mobile Transaction Models

A Database transaction is defined as unit of processes which change a database from one consistent state to another consistent state. Normally a flat transaction follows the basic properties named as ACID (Atomicity, Consistence, Isolation, Durability) properties. In the case of Mobile Transactions, to cope with the problems of mobile environment like handoffs, disconnections etc., ACID properties are generally relaxed. A basic way to relax the ACID property is to divide the transaction into various sub transactions which can be further nested.
