2010 Lecture Notes in Computer Science  
We term the database systems that are customizable for small computing devices as Ubiquitous Database Management Systems (UDBMSs). In this paper, we first review the requirements of the UDBMS.  ...  We then review the supportability of the requirements by those UDBMSs surveyed. We finally present research issues related to the UDBMS.  ...  We deeply appreciate anonymous reviewers' incisive comments on the earlier version that made this paper more complete and readable.  ...
