Problems solved by technology

Therefore, the database with two-level architecture cannot be applied to this kind of multi-level practical needs, and, due to the performance limitation of the central service node, the database with two-level architecture has limitations in scalability
[0005] To sum up, the database systems in the prior art have defects in big data storage and management, and cannot meet the needs of cross-domain deployment of multi-level database systems

Abstract

The invention discloses middleware used for a multilevel database and a multilevel database system. The middleware comprises a task receiving module, a task decomposition module, a task distribution module, and a task execution result statistics module. The task receiving module is used for receiving a task request from a previous node, wherein the previous node is a client or other middleware. The task decomposition module queries a next node executing a sub-task and correspondingly forwards the next node, wherein the next node is a database instance or other middleware. The task execution result statistics module is used for collecting an executive result of the task request from the next node and feeding back the executive result to the previous node. According to the middleware technology, the multilevel database system can be deployed in a cross-domain manner, so that the big data processing capability can be improved and the data management needs of numerous multilevel multi-data centers are met.

Description

technical field [0001] The present invention relates to database technology, more specifically to middleware for multi-level database and multi-level database system. Background technique [0002] In recent years, with the continuous development of information technology, data growth has shown an explosive trend, and massive structured data is increasingly occupying an important proportion. Traditional relational models and relational databases can no longer meet the needs of massive structured data storage under the background of the current big data era. management and analysis needs. [0003] At present, the main problem in the storage, query and analysis of big data is that the data volume of a single database is too large, and the pressure on a single data volume server is too large. In view of the above problems, the main solutions in the existing technology are: upward expansion, that is, continuously increasing hardware performance, this method can only temporarily ...
