挑战

China Telecom, managing a customer base of 250 million ADSL subscribers, was facing a significant challenge with its existing database system. The company's applications relied on the ADSL subscriber database to provide real-time access to hundreds of thousands of account objects. The subscriber database was deployed on a relational database management system (RDBMS), which required a high-performance server that was expensive to maintain. The system was proving too cumbersome over time to keep up with the company’s growing customer base. The company needed a solution that could handle as many as 480,000 queries and 1,000 update transactions per second at peak times, with database performance and reliability being top priorities.

关于客户

China Telecom is a state-owned telecommunications corporation founded in 2002. It is a leader in phone, mobile, Internet and value-added services for commercial and residential customers all over the world. At the end of 2008, the company had 214 million terrestrial phone users, 35 million mobile phone subscribers and 47 million Internet customers. With revenue of more than 220 billion yuan and total assets of 632 billion yuan, China Telecom has been among the Top 500 global corporations for several years running. The company manages a customer base of 250 million ADSL subscribers.

解决方案

China Telecom developers decided to replace the complex centralized RDBMS with a group of low-cost blade servers running an object database in a distributed service network. They chose the Versant Object Database, which provided the company’s applications with a high-performance, distributed persistent data environment. The Versant Object Database manages China Telecom’s ADSL account records as native objects, eliminating any object-relational mapping previously needed when using an RDBMS. The Versant Object Database has been successfully tested by China Telecom to process up to 1,000,000 queries per second. With the ability to deliver outstanding performance, distributed database capabilities and a means of adding servers as query load grew, Versant was named the best Object Database technology by China Telecom.
