This paper presents a context-aware tool for remote database administration that is executed in mobile devices, MDBA (mobile database administrator). The MDBA enables database administrators (DBAs) to perform their tasks by automatically identifying databases and the wireless communication structure of a given mobile computational environment. The proposed tool has properties, which integrate features of mobile computation pervasive computation paradigms and introduces also the notion of remote database administration, which is supported by a new computational paradigm, denoted ubiquitous computation. Therefore, the MDBA tool provides database administration services anywhere and anytime. Furthermore, the MDBA enables DBAs to manage databases residing in mobile hosts or fixed hosts.
