Description

System and method for providing data access for client software

Technical Field

The invention relates to the technical field of software, in particular to a system and a method for providing data access for client software.

Background

Data backup and reading of data in storage equipment are inconvenient, for example, when data of a client is backed up, the data of the client needs to be firstly imported into a computer, and then the computer is connected with the storage equipment to import the data into the storage equipment; when data in the storage device needs to be read, the computer is also required to be connected with the storage device, and then the data in the storage device is read by the computer, so that the client cannot directly read the data of the storage device or directly back up the data to the storage device; automatic backup or reading of data cannot be realized, and therefore, a method and a system for accessing client software are needed, for example, the application numbers are: 201710828511.6, the present invention discloses a data access method and system, the method includes the following steps: s1, binding the ID of the storage device with the client account; the storage device and the client are respectively provided with a private cloud platform; and S2, the client logs in the private cloud platform by using the account, accesses the storage device by using the private cloud platform, and reads the data in the storage device or stores the data in the storage device after the data passes the verification. Although the invention realizes remote data reading and storage, the design must be established on the basis of possessing network connection, and can not be directly stored in the client, and has certain limitation in practical use.

Disclosure of Invention

It is an object of the present invention to provide a system and method for providing data access for client software to solve the above-mentioned problems in the background art.

In order to achieve the above object, the present invention provides a system and method for providing data access for client software, comprising a main system, wherein the main system comprises a database and a client, the database comprises an archive and a storage, and the client comprises an entry window, a main processor, an auxiliary processor and a cache region; the method specifically comprises the following steps:

a. inputting a file name in an input window of a client;

b. searching the files in the archive library through the auxiliary processor, judging whether the files are existing files or not, and building corresponding files in the database and the archive library when the existing files are not searched;

c. extracting the data corresponding to the file from the database and sending the data to a cache region;

d. the main processor opens the data and writes the generated new data into the cache region until the client is closed, and then transmits the latest data back to the storage and updates the original data in a covering manner.

Preferably, the files in the archive library correspond to the file data stored in the storage one to one.

Preferably, the step b specifically comprises the following steps:

(1) determining the byte number of the file name input in the input window, and calling document information with corresponding byte number in the archive by the auxiliary processor;

(2) judging whether the first bytes are consistent or not, and building a corresponding file in the database and the archive library when the first bytes are not searched;

(3) judging whether the second bytes are consistent or not, and when the same second bytes are not searched, establishing a corresponding file in the database and the file library;

(4) comparing each byte one by one until finding out the corresponding file in the archive; and when the corresponding file is not searched, newly building the corresponding file in the database and the archive.

Preferably, the auxiliary processor is operable to read data in the entry window and the archive and to write data in the archive and the storage.

Compared with the prior art, the invention has the beneficial effects that:

the data can be accessed under the condition of network disconnection by storing the data in the main system; furthermore, the method for searching the files in the file library by the auxiliary processor can reduce the flow of searching work and reduce the data quantity to be processed by the auxiliary processor by gradually reducing the searching range, thereby reducing the working pressure of the auxiliary processor; furthermore, the auxiliary processor is arranged, so that the working pressure of the main processor can be reduced.
