The multi-dimensional table data retrieval method provided by the invention can be widely applied to data conversion and retrieval scenes between a complex multi-dimensional table and a huge two-dimensional table, such as fields of economy, government affairs, investment and financing, risk assessment and the like, the database is increasingly enlarged, and a multi-dimensional table data retrieval method is urgently needed to improve the operation efficiency.
Example 1
The multidimensional table data retrieval method provided by the invention can be applied to a computer system, the computer system comprises a terminal and a server, wherein the terminal and the server are in data communication through a communication network, optionally, the communication network can be a wired network or a wireless network, and the communication network can be at least one of a local area network, a metropolitan area network and a wide area network.
The terminal is used for acquiring and storing data, or the terminal is provided with a data processing system for acquiring and storing data, and sending the stored multidimensional table data or real-time data to the server, optionally, the terminal may be a mobile device such as a smart phone, a tablet computer, a laptop portable notebook computer, or the like, or may be a fixed device such as a desktop computer, a projection computer, or the like, which is not limited in the present invention.
The server may be implemented as one server, or may be implemented as a server cluster formed by a group of servers, which may be physical servers, or may be implemented as a cloud server. In one possible embodiment, the server is a backend server of a data processing system within the terminal.
In one example, the server stores data recorded and sent by the terminal, a two-dimensional database is formed (the storage form of the multidimensional table in the database is a two-dimensional mode), when a search task is received, the server acquires target area data from the two-dimensional database according to target position information and performs forward conversion on the target position information to obtain a visual multidimensional table, the target area data is correspondingly stored in the visual multidimensional table, further, the server acquires a retrieval result from the visual multidimensional table according to target positioning information, and finally the server can return the retrieval result to the terminal for display.
In other possible embodiments, the multidimensional table data retrieving method may be implemented as part or all of a terminal function without a server, which is not limited by the present invention.
For convenience of description, the following embodiments are described as examples in which the multidimensional table data retrieval method is executed by a server.
Example 2
Referring to fig. 1, a flowchart of a multidimensional table data retrieval method according to an exemplary embodiment of the present invention is shown. The method comprises the following steps:
And each data in the two-dimensional database corresponds to position information and is stored in an associated manner.
In one example, the value x is the target data, and the value x is stored in the 8 th row and the 5 th column in the two-dimensional table, then the corresponding position information is (8, 5).
And 102, performing forward conversion on the target position information to obtain a visual multi-dimensional table.
The forward conversion is realized according to the mapping relation between the target position information and the visual multi-dimensional table format. The difference between the visual multidimensional table and the two-dimensional database is that the visual multidimensional table is an effective data area obtained according to the target position information, so that the subsequent retrieval process in all databases is omitted, a user can efficiently select and operate the visual target area data in the process of selecting the target data, and a background server does not need to perform full database retrieval and calling.
In one example, the visual multi-dimensional table does not display data outside the target data area, and thus, if the position information of the numerical value x in the two-dimensional table is (8,5), one of the number of rows or the number of columns may be reserved in the visual multi-dimensional table for forward transformation, and if the number of rows is reserved, the position information of the numerical value x in the visual multi-dimensional table is the 8 th row and the 1 st column through forward transformation (i.e., the data of the column before the 5 th column of the numerical value x in the two-dimensional table is not reserved, and the number of columns of the numerical value x is advanced to the 1 st column).
And 103, storing the target area data into the visual multi-dimensional table.
Correspondingly, after the forward conversion of the target area data corresponding to the target area data is completed, the target area data correspondingly stored in the target area data is stored in the visual multi-dimensional table, namely, the target area data is stored after being positioned.
And 104, acquiring a calling result from the visual multi-dimensional table according to the target positioning information, wherein the calling result comprises target data and initial position information of the target data.
The initial position information is the position information of the target data in the two-dimensional database, and the target positioning information is used for indicating the position information of the target data in the visual multi-dimensional table. In the above example, the position information of the value x in the two-dimensional table is (8,5), and after the forward transform, the position information of the value x in the visual multi-dimensional table is the 8 th row and the 1 st column, that is, (8,1), then the initial position information of the target data is (8,5), and the position information of the target data in the visual multi-dimensional table is (8, 1).
In the above example, the forward transform is taken as an example to illustrate the two-dimensional data type, and in fact, the two-dimensional data can be transformed into more than two-dimensional data (related to the visual multidimensional table dimension) through the forward transform.
In summary, in the embodiment of the present invention, when data is retrieved from the multidimensional table, the target area data is first obtained from the two-dimensional database according to the target location information, further, the target location information is forward converted to obtain the visual multidimensional table, and finally, a retrieval result is obtained from the visual multidimensional table according to the target location information. The method provided by the invention realizes the visual conversion of the database, is convenient for the data calling end to call the visual data according to the visual multi-dimensional table, and avoids the problem of slow retrieval caused by directly calling the data in the database; in addition, when the retrieval result is obtained according to the target positioning information, due to the visual data selection, the problem of data error or search fuzziness caused by directly retrieving the target data in the database is avoided, the precision of retrieving the target data is improved, and the method has wide applicability in the field of big data application.

In one possible implementation, in the case of a multidimensional table with a large data size, a preliminary data screening is performed first according to the target field and/or the range in which the target data table is located. In an exemplary scenario, a user selects a field 5 in the data table 1 to call data, and the terminal obtains an area search signal according to a selection trigger operation of the user on a target field and/or a target data table in the multidimensional table, and sends the area search information to a server, and the server obtains the area search signal.
Further, the server determines a data range, namely an indicated area position, which needs to be acquired in the two-dimensional database according to the area search signal, and then summarizes the indicated area position to obtain target position information. For example, the location information of all data in the field 5 area in the data table 1 is summarized to obtain the target location information.
In one possible implementation, the target location information includes at least one of target field location information and target data table location information, and the target field location information may be coordinates of the target field or a set of coordinates of all data within the target field, as well as the target data table location information.
And step 204, acquiring target area data corresponding to the position of the target area from the two-dimensional database.

In step 208, target location information is generated according to the data location indicated by the data selection signal.
And 209, performing inverse transformation on the target positioning information to obtain the position information of the target data in the two-dimensional database, wherein the inverse transformation is realized according to the mapping relation between the visual multi-dimensional table format and the target position information.
