Abstract

The invention provides a data reading method and system, a computer and a readable storage medium, and the method comprises the steps: determining data pages corresponding to the total data amount through SQLite when the total data amount needing to be read is obtained, and obtaining a data cursor corresponding to each data page; when the data needs to be read, judging whether the data which needs to be read at present is in a preset memory cache region or not; if yes, directly reading the data from the memory cache region; and if not, reading the data in the corresponding data pages through the data cursor, and storing the read data in the memory cache region. The memory cache region provided by the invention only loads the data of one data page at most (totally three memory cache regions), and each data page only reads the data once from the SQLite, so that the data reading and loading times are greatly reduced, the calculation frequency of the system is correspondingly reduced, and the query speed of the data is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data reading method, system, computer and readable storage medium. Background technique [0002] With the continuous advancement of science and technology, Internet technology has also developed rapidly, and the Internet has been popularized in people's daily life, so that people can study, work and entertain on the Internet. [0003] Among them, the embedded system is composed of hardware and software, and is a device that can operate independently. Its software content only includes the software operating environment and its operating system. The hardware content includes many aspects including signal processor, memory, communication module and so on. Compared with general computer processing systems, the computing resources and memory resources of embedded systems are small, so that in the scenario of continuously reading data from the sliding device screen...
