As technological advances are made in software and hardware, the feasibility of accessing information "any time, anywhere" is becoming a reality. In a mobile computing environment, a potentially large number of mobile and fixed users may simultaneously access shared data; therefore, there is a need to provide a means to allow concurrent management of transactions. Specific characteristics of mobile environments make traditional transaction management techniques no longer appropriate. This is due to a fact that the ACID properties of transactions are not simply followed, in particular the atomicity property. Thus, transaction management models adopting weaker forms of atomicity are needed. In the first part of this thesis, a performance evaluation of three common execution strategies for mobile transactions, the mobile host strategy (MHS), the fixed host strategy (FHS), and the combined host strategy (CHS), is conducted.
