Mobile computing may be considered a variation of distributed computing. Faults can be classified in two types: transient and permanent. There is most efficient access of data and higher security is available. Higher data availability and low cost of remote access is there in data distribution and replication. Database management system engines. In mobile environment, the issues of correctness of transactions and fault tolerance are aggravated. Because of the frequent shutdown and for handling the queries, the global name resolution problem is compounded. Security – The data which is left at the fixed location is more secure as compared to mobile data. It process their own transactions. Mobile computing involves mobile communication, mobile hardware, and mobile software. Comments. Security – The data which is left at the fixed location is more secure as compared to mobile data. Open Access. Information systems. Eviction techniques are important in this case.Issues that arises in location and services are: Updation of the location dependent queries and then applying spatial queries to refresh the cache causes a problem. There is a requirement of dynamic optimization strategies in the mobile distributed context. Due to failure of MU, there is a big cause of network partitioning and affection of the routing algorithms. One of the most challenging tasks which must be undertaken is determining the location of mobile users, which must be undertaken in order to enable a location based service. Here are some of the issues which arises in data management of the mobile databases: 1. Engineering College, Gorakhpur Abstract— Recent advances in wireless communication networks and portable computers have led to the emergence of a new In mobile computing platform information between process units flows through wireless channels. The most important thing needed in this environment is the authorizing access to critical data and proper techniques. Improper and unethical practices such as hacking, industrial espionage, pirating, online fraud and malicious destruction are some but few of the problems experienced by mobile computing. All transactions must satisfy the ACID properties, these are atomic, consistency, isolation, and durability. The mobile database environment must deal with site, transaction, media, and communication failures. There are four possible invalidation mechanisms Stateless asynchronous, stateless synchronous, stateful asynchronous and stateful synchronous.
