Disk-based database systems are widely used, offering a great set of functionalities perfectly suited for most kinds of applications. However, when high performance is the priority, such databases are unable to produce satisfactory results. Telecom applications demand high performance especially for their real-time applications. Location management is one of many telecom applications that fall into this category. Currently, location information is managed by custom-developed applications requiring the use of proprietary API’s and custom data models to achieve the performance expectations. This paper summarizes some possible approaches to handle the location problem in the telecom industry using main-memory database systems. Such systems have been proven able to deliver high response-time, throughput and reliability.
