Many of the software systems we use for everyday purposes incorporate elements developed and maintained by third parties. These elements include not only code components and data bases but also dynamic data feeds from online data sources. Even though everyday software is not mission critical it must be dependable enough for its intended use. This is limited by the dependability of its constitut...

Data distribution is one of the crucial issues in Data Base Management Systems (DBMS) in general and in Mobile environment in Particular. It is important because, if not properly managed, it will cause reduction in data availability, which in turn causes more rejections in transactions.
