http remote data access system and method

Abstract

The invention relates to an HTTP remote data access system and method. An HTTP request is sent to a middle layer server through a client terminal. A corresponding query result is obtained from a database server according to access data by the middle layer server, and the query result is converted into a JOSN format and is sent to the client terminal. Remote access is carried out with the JOSN as a data carrier, data exchange can be carried out between different platforms, cross platform implementation can be realized, and the bandwidth occupied in a transmission process is relatively smaller. The JOSN file format determines easy analysis in a data transmission process, so that codes are simple and are maintained easily, and a client is avoided repeatedly compiling codes with the same function. Compared with the traditional HTTP remote data access method, the data query efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cross-internet data access, in particular to an HTTP remote data access system and method. Background technique [0002] With the advent of the big data era, distributed computing, distributed server clusters, distributed storage, etc. have become a trend. The rapid expansion of the server will inevitably lead to the situation that the application server and the database server are not in the same local area network. For the database, security is particularly important. In order to prevent malicious attacks from the external network, the database will prohibit external network access. [0003] The traditional HTTP remote data access method is a heterogeneous database integration method based on XML and Web Service technology, using XML as the data carrier. The access to the Web database adopts the browser / Web server (B / S) or browser / Web server / database server (B / S / S) structure. The client sends a reques...

AI Technical Summary

Problems solved by technology

[0004] The data is transmitted in XML data format, the data redundancy is high, the file format is complex, and the transmission takes up bandwidth; both the server and the client need to spend a lot of code to parse the XML during the data transmission process, resulting in server and client code becoming It is extremely complex and difficult to maintain; the way of parsing XML between different browsers on the client side is inconsistent, and a lot of code needs to be written repeatedly; due to the above, it takes more resources and time to parse XML on the server side and the client side

Therefore, the traditional HTTP remote data access method has the disadvantage of low data query efficiency
