The emergence of mobile computing provides the ability to access information at any time and place. Ubiquitous data access is the base of mobile computing and connectivity. Organizing and accessing massive amount of data on wireless communication networks in order to provide fast and low power access to users equipped with wireless devices is a new challenge to the data management and telecommunication communities. This paper provides a brief introduction to mobile database architecture, and enlist important issues related to management of data on move which could be available everywhere. The use of wireless communication makes the data availability the most important problem here especially for location dependent data. It further states the problem associated with Location dependent data in caching, cache invalidation and cache replacement.
