example

[0072] (1) Build a cloud computing platform, which consists of a master node and several slave nodes. The master node is used to send queries, and the slave nodes are used to store multidimensional data objects, receive queries and return query results to users.

[0073] Such as figure 2 As shown, there are 10 machines in the cloud computing platform, 2 of which are used as master nodes to store the global index of the entire platform and receive user query requests, and the other 8 machines are used as slave nodes to store data objects and process query requests. The 8 slave nodes are clustered by using the IDBC algorithm proposed by the present invention to form 3 slave node clusters, so that the slave nodes in each slave node cluster store data objects with similar information.

[0074] (2) Use IDBC algorithm to divide all slave nodes into multiple clusters, so that slave nodes in the same cluster contain similar data objects to process queries.

Abstract

The invention discloses a multi-dimensional data management-oriented cloud computing query processing method, belonging to the field of database. The method comprises the following steps: 1, building a cloud computing platform which consists of a master node and multiple slave nodes, wherein the master node is used for sending queries; the slave nodes are used for storing multi-dimensional data objects, receiving queries and returning the query results to users; and the master node and the slave nodes are connected through Internet; 2, dividing all slave nodes into multiple clusters with an IDBC (information density based clustering) algorithm so that the slave nodes in the same cluster have similar data objects; 3, creating a quadtree-based multi-dimensional index for each slave node cluster, and organizing the quadtree-based multi-dimensional indexes in a CAN (content addressable network); and 4, performing query processing.

Description

technical field [0001] The invention belongs to the field of databases, and in particular relates to a design of a query processing method for a cloud computing platform, in particular to a design of a query processing method for a cloud computing platform oriented to multidimensional data management. Background technique [0002] With the rapid development of computer and Internet technology, cloud computing has gained more and more attention as a new computing platform. Cloud computing is an improved treatment of distributed processing, parallel processing and grid computing. A cloud computing platform consists of a large number of machine nodes that store data objects and perform computing tasks. figure 1 The basic structure of a traditional cloud computing platform is given. figure 1 There are two types of machine nodes: master nodes and slave nodes. The master node usually stores the metadata information of the entire platform, and the slave nodes are mainly responsi...
