FIG. 1 is a schematic diagram of one application scenario of a method for synchronizing data, in accordance with some embodiments of the present disclosure; in the application scenario of fig. 1, the execution agent may be a thread. The execution main body receives input data input by a user on a target terminal and acquires a data identifier of the input data. And determining whether the data identifier exists in the cache, if so, determining whether the state value of the data identifier changes, if so, determining whether the data identifier and the input data exist in the database, and if so, storing the data identifier and the state value into the cache. And if the data identifier does not exist, determining whether the data identifier and the state value exist in the database, and if the data identifier and the state value do not exist, generating the data identifier and the state value in a cache, and synchronously storing the data identifier and the state value in the database. By way of example, it may be that a worker modifies a person's name on a corporate person registry and the input data may be the name to be modified. For example, originally "Zhang shan", modified to "Zhang shan". Here, the data identification may be the employee's job number, e.g., "0001". When the worker clicks on save and/or refresh after modification, the executive entity will find the buffer zone to look for "0001" and the status value will change because the data is modified. The execution subject will look up job number "0001" in the database, and if no job number "0001" exists in the database, the job number "0001" and the state value corresponding to the job number are generated in the cache region. And storing the generated job number, state value and name into a database.
The execution main body may be hardware or software. When the execution main body is hardware, the execution main body can be implemented as a distributed cluster consisting of a plurality of servers or terminal devices, and can also be implemented as a single server or a single terminal device. When the execution body is embodied as software, it may be implemented as a plurality of software or software modules for providing distributed services, for example, or as a single software or software module. But also a thread or process. And is not particularly limited herein.
With continued reference to fig. 2, a flow 200 of some embodiments of a method for synchronizing data in accordance with the present disclosure is shown. The method for synchronizing data comprises the following steps:
step 201, receiving input data input by a user on a target terminal.
In some embodiments, the executive may receive input data entered by the user on the target terminal. The target terminal may be a terminal within the enterprise that is capable of viewing and modifying internal data. Such as a company data monitoring personnel computer. The input data may be employee information added or modified. Employee information may include, but is not limited to, at least one of: job number, name, department, job title, etc. For example, a piece of employee information is added. The job number may be "1001" and the name may be "lie".
Step 202, acquiring the data identifier of the input data.
In some embodiments, the execution subject obtains a data identification of the input data. The data identification is typically an identification corresponding to the input data. Taking the above example as an example, the data identifier may be a job number.
Step 203, determining whether the data identifier exists in the cache of the target terminal according to the data identifier.
In some embodiments, the execution subject may search, according to the obtained data identifier, whether the data identifier exists in the cache region. Taking the above example as an example, a piece of employee information is added, and since the job number and the name are both added, the data identifier in the cache area does not exist. If the name in the employee information is modified, for example, the name of the employee with the employee number "0001" is modified to "lie". Because the job number is already present and the name is modified, the data identification is present.
Step 204, in response to determining that the data identifier exists in the cache of the target terminal, determining whether a state value of the data identifier in the cache changes.
In some embodiments, the execution subject may determine whether a state value of the data identifier changes according to the data identifier. The above state value is generally used to characterize the time from the last use of the data, and the state value is larger the longer the time, for example, when a piece of data is newly added, the state value may be "1". As an example, the input data may be to modify a name in the employee information, e.g., to modify the name of an employee with an employee number of "0001" as "lie". Because the job number is already present and the name is modified, the data identification is present, but the input data is not. The state value of the data identity typically changes. And if no input data exists, only refreshing the page of the display data on the target terminal. Then the data identity is already present and the input data is also already present and the state value of the data identity is not normally changed.
In some optional implementation manners of some embodiments, in response to determining that the data identifier does not exist in the cache of the target terminal, whether the data identifier and the input data exist in a database storing data on the target terminal is determined according to the data identifier. For example, if the staff adds the staff information to the target terminal or the staff directly adds the staff information to the database, the data identifier may not exist in the cache.
Step 205, in response to determining that the change occurs, determining whether the data identifier and the input data exist in a database of data stored on the target terminal according to the data identifier.
In some embodiments, the execution subject may search the database for the presence of the data identifier according to the data identifier when the status value of the data identifier changes. As an example, the input data may be a name in the modified employee information, and the status value of the data identification will typically change. The data identification described above, e.g., job number "0001", is typically found in a database. The input data is typically not found in the database.
In some optional implementations of some embodiments, in response to determining that no change has occurred, sending, to the target terminal, a prompt that a state value of a data identifier characterizing the input data is not updated. The prompt information may be information indicating that the state value of the data identifier representing the input data is not updated, for example, "state value is not updated".
Step 206, in response to determining that the data identifier and the input data exist in the database, synchronously saving the data identifier and the state value of the data identifier in the database into the cache.
In some embodiments, the data identification and the input data are based on the presence of the database. And synchronously storing the data identifier in the database and the state value of the data identifier in the cache. As an example, when the staff directly adds the staff information to the database and refreshes the staff information on the target terminal, the data identifier and the input data corresponding to the input data may not exist in the cache, but the data identifier and the input data corresponding to the input data may exist in the database. At this time, the data identifier corresponding to the input data in the database and the state value of the data identifier may be saved in the cache.
In some optional implementations of some embodiments, in response to determining that the data identifier and the input data do not exist in the stored number database, generating a data identifier of the input data and a state value of the data identifier in a cache of the target terminal; and synchronously storing the data identifier of the input data and the state value of the data identifier into the database. As an example, when the staff adds the staff information to the target terminal, the data identifier and the input data may not exist in the database. The execution subject may invoke a thread to generate a data identifier of the input data and a state value of the data identifier in a cache according to the input data. And storing the generated data identification and the state value of the data identification into the database.
In some optional implementations of some embodiments, further reference may be made to fig. 3, which illustrates aflow 300 of further embodiments of a method for synchronizing data according to the present disclosure. The method for synchronizing data comprises the following steps:
In some embodiments, the execution principal may receive user input data on the target input page. The target input page may be a page where data operations may be performed on the database. The data operations include, but are not limited to, at least one of: a lookup operation, an add operation, a modify operation, and a delete operation. The data may be data in a database table, for example. Employee names in an employee information table.
In some embodiments, the database is queried for the data received instep 301 to determine whether the data exists in the database. Here, the execution body may look up the above data in a database.
In some embodiments, based on determining that the data does not exist in the database, the execution principal may generate a data identifier of the data and a status value of the data identifier from the data.
In some optional implementations of some embodiments, the status value of the data identification of the data is updated in response to determining that the data exists in the database. Here, when the data exists in the database, the execution principal generally updates the state value of the data identifier of the data. For example, the status value of the data identifier of the data is originally "10", and the executing entity may update the status value of the data identifier of the data to "1" because the lookup operation is performed on the data.
In some embodiments, the data identifier of the data and the state value of the data identifier generated instep 303 are saved in the cache.
In some optional implementation manners of some embodiments, when the state value of the data identifier in the cache of the target terminal is greater than or equal to a preset threshold, a prompt message for deleting the data identifier corresponding to the state value of the data identifier in the cache of the target terminal is generated. And sending the prompt information to the terminal equipment for monitoring data. Here, the preset threshold may be set manually. The prompt information may be information for prompting deletion of the data identification, for example, "please delete the present data identification". The terminal device for monitoring data may be a device having the authority to monitor data, for example, a computer of a staff member for monitoring data inside an enterprise.
Some embodiments of the present disclosure disclose a method for synchronizing data, which enables synchronized storage of data identifiers and state values of the data identifiers in a cache and a database. Therefore, the memory consumption is reduced when the data is quickly searched and refreshed, and the working efficiency is improved.
