Embodiment 1

[0029] Figure 1a It is a flow chart of the data display method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of displaying data in a data list. The method can be executed by a data display device and can be integrated into a computer device. Wherein, the method includes:

[0030] S110. Determine the position of the current display area on the page in the data set to be displayed, where the data set is stored in a persistent storage layer.

[0031] Wherein, the page is a user interface (UI), and generally includes a filter control and a list control, wherein the filter control is used to determine the query conditions input by the user, so that the device can filter out the relevant information from the persistent storage layer according to the query conditions. The corresponding data set to be displayed, and determine the number of entries in the data set. The list control can include a data display area and a scroll control. Th...

Embodiment 2

[0045] figure 2 It is a schematic flow chart of the data display method provided by Embodiment 2 of the present invention. This embodiment is based on the above embodiment, after "reading the data corresponding to the position in the data set from the buffer and displaying it on the page" in S130, the method Further optimization, specifically, as figure 2 As shown, the method also includes:

[0046] S210. Obtain an updated position in the data set of the current display area on the page after updating.

[0047] On the user interface, the user can update the data displayed in the display area in real time by controlling a scroll control (such as a scroll bar). Therefore, it is necessary to first determine the scroll position of the scroll control in the data display area after scrolling, so as to determine the update position of the updated current display area on the page in the corresponding data set according to the scroll position.

[0048] S220. Determine, according ...

Embodiment 3

[0060] image 3 It is a schematic flow chart of the data display method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, "if the update data hits the buffer data in the buffer, read the update data from the buffer in the displayed on the above page", the specific optimization is:

[0061] Finding the corresponding node in the balanced binary tree according to the update position;

[0062] If there is a node corresponding to the update position in the balanced binary tree, the update data corresponding to the update position in the data set is pulled from the data block pointed to by the node and displayed on the page.

[0063] Correspondingly, the data presentation method provided in this embodiment specifically includes:

[0064] S310. Obtain an updated position in the data set of the current display area on the page after updating.

[0065] S320. Determine, according to the update p...

Abstract

The embodiment of the invention discloses a data displaying method, device, equipment and a storage medium. The method comprises the steps of determining the position of a current display area in a to-be-displayed data set on a page, wherein the data set is stored in a persistent storage layer; reading buffered data from the persistent storage layer into a buffer area according to the position, wherein the buffer area corresponds to the data set and is pre-established in a memory, and the buffered data includes the position and corresponding data of a neighboring position in the data set; reading the corresponding data of the position in the data set from the buffer area and displaying the data on the page. According to the embodiment, display of a large amount of data under a limited amount of memory is achieved without data access speed restriction.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data display method, device, equipment and storage medium. Background technique [0002] Lists and spreadsheets are commonly used software data visualization solutions, which present data to users on a user interface (UI) in the form of rows and columns. When there is a lot of data to be displayed, it is usually convenient for users to browse through paging or scrolling. Relatively speaking, using the scroll bar method allows users to select and change multiple rows of data at the same time, which has a better interactive experience than the pagination method. [0003] At present, when displaying data in the form of a scroll bar, there are mainly the following two solutions: 1) Store all the data to be displayed in the memory, and directly read the current data to be displayed from the memory according to the scroll position of the scroll bar. This improves the disp...
