The Design And Implementation Of Distributed Database Based On Oracle Of Mobile CRBT

This paper introduces the development of distributed database and its basic theoretical knowledge, polyphonic ringtones, communication principle, the internal communication structure of ring tones, combined with the relevant principles of ORACLE database using the oracle advanced replication technology for distributed database systems; to mobile ring tones system as the background for the ring tones business characteristics, the data in the database production system, designed for the business is structured into ring tones and call flow management processes, some of the data structure CRBT also divided into management nodes and call nodes, Tong on the basis of analysis of business background, combined with Jilin Mobile Communication Network of the actual situation, and based on the success of Oracle's distributed database system used in mobile ring tones. And discuss implementation issues of data consistency and made through the advanced replication, a reasonable solution automatic data replication cycle of weak consistency and processing time lag problem.
