Embodiment 1

[0031] The embodiment of the present invention provides a data storage method, which can be applied to large institutions such as banks, governments, companies, etc., in specific application scenarios where data with different access frequencies needs to be stored. The data storage method in this embodiment is as follows: figure 2 shown, including:

[0032] Step S11: Obtain the data to be stored. The attribute of the data to be stored is cold data by default. The attribute of the data includes hot data or cold data. Store the attribute information of the data to be stored in the data management area. The data management area is set in the memory storage space; in this embodiment, the data to be stored can be data information such as customer assets and income and expenditure details in the banking system, or data information such as meeting records and policy changes in the government system, or company system Data information such as purchases and expenditures in China, the ...

Embodiment 2

[0046] The embodiment of the present invention provides a method for reading data, which can be applied to mobile terminals or service personnel in large institutions such as banks, governments, and companies, and needs to read stored data in specific application scenarios. In this embodiment, The method of reading data, such as image 3 shown, including:

[0047] Step S21: Obtain the data to be read; in this embodiment, the data to be read may be the data stored in the above embodiments, for example, when the user queries the balance information, it is necessary to read the pre-stored user balance data, To get the user's current balance.

[0048] Step S22: Determine whether the attribute of the data to be read is hot data; the hot data refers to the data stored in the hard disk through the data storage method described in any of the above embodiments. Exemplarily, the attribute information of the data may be hot data or cold data. When the data is hot data, it means that th...

Embodiment 3

[0061] The embodiment of the present invention provides a data storage device, which can be applied to large institutions such as banks, governments, companies, etc., in specific application scenarios that need to store data with different access frequencies, such as Figure 4 shown, including:

[0062] The first obtaining module 31 is used to obtain the data to be stored. The attribute of the data to be stored is cold data by default, and the attribute of the data includes hot data or cold data, and is used to store the attribute information of the data to be stored in the data management area. The management area is a storage space set in the internal memory. For detailed implementation content, please refer to the relevant description of step S11 in the above method embodiment.

[0063] The first judging module 32 is used to judge whether the access frequency of the data to be stored is greater than or equal to the preset access frequency, the data whose access frequency is...

Abstract

The invention discloses a data storage method, device and system, and the method comprises the steps: obtaining to-be-stored data, and storing the attribute information of the to-be-stored data into adata management region; judging whether the access frequency of the to-be-stored data is greater than or equal to a preset access frequency or not, and when the access frequency is greater than or equal to the preset access frequency, modifying the attribute information of the data in the data management area, and storing the hot data into a hard disk; acquiring a storage position of the hot datain the hard disk, and storing storage position information into a data management area; writing all to-be-stored data into an optical disk library; obtaining the storage positions of all the to-be-stored data in the optical disk library, and storing the storage position information into the data management area. By implementing the method and the device, different steps are adopted to store the data in combination with different attribute information of the to-be-stored data, so that the problem that in the existing data storage technology, the data needs to be subjected to magnetic bufferingand / or electric buffering firstly and then is stored into an optical disk is solved, and the service life of media such as a magnetic disk is prolonged.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data storage method, device and system. Background technique [0002] In the era of big data, many enterprises store a large amount of data. According to different data application frequencies and application scenarios, data can be classified and stored in different media to save costs. Among the existing storage technologies, the combination of disk arrays and tape libraries for data storage is still the mainstream technology that will be used in data centers to store data. The existing storage methods are to first buffer the data to the memory and then store it on the disk. , wait for the data to cool down, and then save it to the disc. After a series of processing, all the original data is finally stored on the CD for storage. Since disks and other media have a limit on the number of reads and writes, when storing large amounts of data, multiple reads and writes will seriously ...
