Abstract
This paper presents practical and empirical approach to the main memory database system and proposes a minimal database system with real-time mobile data management functionality. It introduces a mobile computational viewpoint and gives a full detail of design considerations of real-time main memory database. As a case study, we present how to apply it to location registers in order to achieve both higher performance and a large volume of database capacity. It has a down-sized client/server architecture, including a relational data model, fast access methods, and middleware. This minimal real-time database system goes into use both mobility and subscriber management in a modern digital cellular system.
