Problems solved by technology

[0009] In order to overcome the problem of insufficient timeliness of data views in existing big data visualization methods, the present invention proposes a data view copy iteration method in a Web visualization environment, materializes and caches the visualization results, and improves the data view through the copy iteration method. The update efficiency of views avoids the impact of frequent updates on query performance and reduces the retrieval overhead of data views; this method can quickly query and visualize massive data in a web environment with large query sets and frequent data source updates ; and ensure that existing users who are accessing the data view are not affected when updating the cache

Embodiment Construction

[0086] The present invention will be further described below in conjunction with the accompanying drawings.

[0087] refer to Figure 1 ~ Figure 3 , a data view copy iteration method in a Web visualization environment, the copy iteration method includes the following steps:

[0088] The first step is to establish a dynamic evolution model, which is designed according to the idea of ​​layered architecture, such as figure 1 As shown, it is divided into big data user layer, big data visualization layer and big data source layer;

[0089]1.1. Big data user layer: It is composed of users (users) with different big data visualization requirements on the network. Users can obtain interested big data information by accessing the big data visualization layer. The user layer does not depend on the specific technical architecture and can Customize different views in the visualization layer to analyze multiple dimensions of data.

[0090] 1.2. Big data visualization layer: Based on the...

Abstract

The invention discloses a data view copy iteration method in a Web visual environment. The method comprises the following steps of S1, establishing a dynamic evolution model which comprises a big data user layer, a big data visual layer and a big data source layer; and S2, providing the data view copy iteration method in the Web visual environment based on the model. According to the data view copy iteration method in the Web visual environment provided by the invention, a visual result is materialized and cached; the updating efficiency of data views is improved through the copy iteration method; the search performance is prevented from being influenced by frequent updating; and the search cost of the data views is reduced. According to the method, in the Web environment with a relatively big search set and a relatively frequently updated data source, massive data can be searched rapidly and displayed visually, and the user currently accessing the data views is not influenced when the cache is updated.

Description

technical field [0001] The invention relates to the field of data visualization, in particular to a data view copy iteration method in a Web visualization environment. Background technique [0002] With the rapid development of information technology such as the Internet, the Internet of Things, and cloud computing, information technology and all aspects of human politics, economy, military, scientific research, and life are constantly intersecting and merging, giving birth to a huge amount of data beyond any previous era. Therefore, the information society We have entered the era of Big Data. All kinds of smart mobile devices, sensors, e-commerce websites, and social networks all over the world are generating different types of data every moment. According to the "Data Universe" report of the International Data Corporation (IDC), the global data volume was 0.5ZB in 2008 and 1.2ZB in 2010, and mankind has officially entered the ZB era. What is even more astonishing is that...
