The terminal 102 may process the power data in the target data table according to the processing method information. For example, data may be added, deleted, modified, etc. Wherein each process may employ a different approach.
In the data processing method, after a data processing instruction triggered by a user in a system is acquired, a data identifier of power data to be processed is acquired from a private first memory space corresponding to the user, a target data table corresponding to the power data to be processed is determined from a file system of a second memory space according to the data identifier, wherein the second memory space is a public memory space used for storing the power data, and finally the power data in the target data table is processed according to processing mode information in the data processing instruction. Compared with the traditional method for processing the electric power data by utilizing the open source memory bank and the like, the method and the device have the advantages that the electric power data are quickly, simply and conveniently processed through the data table and the memory space separating mode, and the electric power data processing efficiency is improved.
In one embodiment, in response to a data processing instruction triggered by a user, before acquiring a data identifier of power data to be processed from a first memory space corresponding to the user, the method further includes: detecting whether a data identifier corresponding to the electric power data to be processed exists in the identifier table; if not, a data identifier corresponding to the to-be-processed power data is created in the identifier table, and an association relation between the data identifier and the to-be-processed power data is established.
In this embodiment, the first memory space may be a private space in the memory of the terminal 102, and the first memory space may include an identifier table, where the data identifier may be stored in the identifier table, and the identifier table includes at least one data identifier; specifically, the indication table may be an index table, and the index table may include a plurality of indexes. The terminal 102 may create a data identifier as needed, and before responding to a data processing instruction triggered by a user, the terminal 102 may detect whether a data identifier corresponding to the to-be-processed power data exists in the indication table, and if so, may obtain a data table in which the to-be-processed power data is located according to the data identifier; if not, the terminal 102 may create a data identifier corresponding to the to-be-processed power data in the identifier table, and create an association relationship between the newly created data identifier and the to-be-processed power data.

In this embodiment, the system may include a plurality of processes, and each process may correspond to a user one by one; that is, each process may have a corresponding first memory space, the power data is stored in a mapping file, the index is not stored in a file, the user may be set up in a private memory, and each user may set up its own index in the process. Therefore, in the case of multiple processes, it is desirable to avoid multiple processes from processing power data simultaneously. The terminal 102 may respond to a data processing instruction triggered by a user in the system, add a process lock to a current process corresponding to the user, and switch a state of a target data table corresponding to the data processing instruction to an in-use state, thereby preventing processes corresponding to other users from processing power data in the target data table. The target data table may be a data table where the power data to be processed is located.
In one embodiment, after processing the power data in the target data table according to the processing mode information, the method further includes: and releasing the process lock, and switching the state of the target data table to an unused state.
In this embodiment, the terminal 102 may release the process lock after the data processing is completed in the current process, so as to switch the state of the target data table to an unused state, and the data table in the unused state may be processed by other processes.
Specifically, as shown in fig. 7, fig. 7 is a flowchart illustrating steps of a multi-process in one embodiment. The process 1 may create a memory base table, that is, the above-mentioned data table, in a file mapping manner, and then may create index data in the private memory of the process 1 as needed, the process 2 may open a file corresponding to the table name in a file mapping manner, so as to implement sharing of power data, and the process 2 may also create index data in the private memory thereof as needed, and the index data of each process may be different and do not affect each other. When any process processes the power data, the terminal 102 may add a process lock in a file lock manner, modify the state value of the data table at the same time, avoid multiple processes processing the power data at the same time, and may release the process lock and modify the state value after the processing is completed.
Through the embodiment, the terminal 102 can realize the mutual exclusion processing of the modification of the data table by using the process lock and the modification state value under the condition of a plurality of processes, so that the plurality of processes are prevented from processing the power data at the same time, and the safety of the power data is improved.
In one embodiment, processing the power data in the target data table according to the processing mode information includes: if the processing mode information is data increase, power data to be increased are added at the tail end of the target data table; the power data to be increased is determined by the user; if the processing mode information is the deleted data, replacing the power data in the target data table with the null data; if the processing mode information is modification data, determining the content needing to be modified according to the data identification and the power data to be modified; the power data to be modified is determined by the user.
In this embodiment, the processing mode information may be information in the data processing instruction, and the processing mode information may include: at least one of adding data, deleting data, and modifying data. The terminal 102 may perform different processing on the power data to be processed according to different processing mode information. If the processing mode information is adding data, the terminal 102 may add power data to be added at the end of the target data table, where the power data to be added may be determined by a user. Specifically, the terminal 102 may obtain a new memory location from the current location pointer, where the new memory location is at the original end, and directly copy the power data to be newly added in the recorded memory, that is, the target data table, so as to complete the addition of the power data. If the processing mode is to delete information, the terminal 102 may replace the power data in the target data table with null data, so as to delete the power data. Specifically, the deletion of the power data may be realized by replacing the target data table with data at different positions.
If the processing mode information is modification data, the terminal 102 may determine the content to be modified according to the data identifier and the power data to be modified, where the power data to be modified may be determined by a user. Specifically, in one embodiment, determining the content to be modified according to the data identifier and the power data to be modified includes: judging whether the power data to be modified is power data corresponding to the data identifier; if not, determining the content needing to be modified as the power data to be modified; and if so, determining the content needing to be modified as the power data to be modified and the data identification corresponding to the power data to be modified. The terminal 102 may determine whether only the power data or both the power data and its corresponding data identifier need to be modified according to whether the data identifier is related to the power data to be modified. The terminal 102 may locate a corresponding position in the corresponding data table that needs to be modified according to the content that needs to be modified, and then modify a corresponding field according to the power data to be modified, if the modified field is not an index, that is, the data identifier, the corresponding field does not need to be processed, and if there is some index related to the modified field, the current index record is reconstructed.
Through the embodiment, the terminal 102 can perform corresponding processing on the power data to be processed by using the data identifier and the data table according to different processing mode information, so that the efficiency of processing the power data is improved.

In this embodiment, the terminal 102 may determine the remaining size of the second memory space before increasing the power data, so as to determine whether to increase the memory. The terminal 102 may determine whether the size of the power data to be added is larger than the remaining space of the second memory space, and if not, the terminal 102 may directly add the power data to be added to the data table; if not, the terminal 102 may increase the size of the second memory space, so as to store the power data to be increased. Specifically, the terminal 102 may increase the size of the second memory space according to a dichotomy, where the size of the memory allocated in the center may be 2 times of the current size when the memory needs to be expanded again due to insufficient storage.
