Method for storing navigation data by using embedded database in cloud computing environment

Abstract

The invention discloses a method for storing navigation data by using an embedded database in a cloud computing environment. The method comprises the following steps of a) establishing a cloud computing platform; b) initializing a management node A; c) registering all service nodes participating in cloud computing to the management node A; d) summarizing and combining obtained navigation data information on the management node A and storing the data by using the embedded database; e) storing the data by utilizing an embedded database engine of the node after the navigation data information sent by the management node A is received through a data storage node D and a service provision node S, and starting to provide services; and f) when node information in the cloud platform is changed, updating the embedded database in the management node A by the management node A. Complex software and hardware equipment and multiple development languages in the cloud computing environment can be adapted; the method does not depend on specific equipment or software; the data is put in a memory for execution; and the method has the advantages of high efficiency, few occupied resources, no influence on normal business execution and the like.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method for storing navigation data in an embedded database under a cloud computing environment. Background technique [0002] At present, the mainstream way of cloud computing node navigation data information storage is still realized through traditional modes. These modes include storing in text file formats such as txt, storing in XML format files by application architecture, and using data tables of relational databases. to store. [0003] In the new cloud computing environment, the traditional model has the following problems: [0004] 1. Use TXT or XML format files to store in the operating system. It is easy for the system administrator to directly see and modify the contents of the files, and the read and write permissions of the files are affected by the directory permissions of the operating system. Easily seen by other users in the operating system. Moreover, operati...

Problems solved by technology

And the operation in the text file format does not support rollback and undo misoperation, and does not support transactions (Transaction)

[0005] 2. Using relational database storage, although it can support transaction operations and roll back misoperations, due to its complex structure, it cannot meet the needs of real-time response in terms of execution efficiency

[0007] The current mainstream cloud computing platform and conventional tools, in terms of security and transaction support, conventional file storage cannot do; and in terms of efficiency, conventional relational database management systems cannot satisfy users' real-time response requirements
