Research and Analysis on Key Points of Distributed Database Application in Telecom Support System

With the rapid growth of data, traditional databases have storage and performance bottlenecks which are difficult to meet the requirements of data storage and application. Distributed database, with its characteristics of high expansion, low cost and high performance, has brought new and efficient solutions for massive data storage and has been vigorously developed. Data access performance is the main indicator to measure the performance of distributed database. By studying the relationship between data storage and access performance of distributed database, this paper puts forward the objective function of data access performance. Through quantitative analysis of database partition, cache design and other technologies used in the design of distributed database in optimizing data access performance, this paper gives the key points of data partitioning, cache design and other technologies used in distributed database, It provides a new idea for the transformation on the focus of database design in the telecommunications support system from qualitative analysis to quantitative analysis. At the same time, taking the telecommunications support system as an example, the impact of data partition technology and cache design technology on application performance is verified through experiments.
