Referring to fig. 2, fig. 2 is a flowchart illustrating a method for generating a data storage path according to an embodiment of the present disclosure. As shown in fig. 2, a method for generating a data storage path according to an embodiment of the present application includes:
In this step, a plurality of pieces of data already stored in the database, and location identification information and time information corresponding to each piece of the plurality of pieces of data are acquired.
Here, the data may include spatio-temporal trajectory data, and the place identification information refers to a unique Identification (ID) of a place corresponding to the data, the place ID being converted from a point space, an administrative space, an absolute space, and a traffic space of the spatio-temporal trajectory data through an algorithm.
For example, the position of the geographic position of a hotel in an absolute position (longitude and latitude) is (60 ° N, 132 ° E) through a preset corresponding rule, and the location identification information of the hotel is 100; for the same hotel, the hotel belongs to a beijing city sea area in the administrative district dimension, and then the location identification information of the hotel may also be 001.
Here, the time information may include a collection time of the data, that is, a time collected by the collection device, or an upload time of the data uploaded to the database by the collection device.
In the step, according to all data information corresponding to the acquired data, determining all unrepeated data identification information corresponding to all the data, wherein each type of data identification information corresponds to a primary catalog, and associating the data with the same data identification information with the catalog corresponding to the data identification information.
Here, when determining the primary directory according to the location identification information, the primary directory may be the same as the location identification indicated by the location identification information, or the primary directory may be different from the location identification indicated by the location identification information, for example, if the location identification indicated by the location identification information is the same, if the location identification indicated by the location identification information is 100, the primary directory is also 100; if the location identifications indicated by the location identification information are different, if the location identification indicated by the location identification information is 100, the primary directory may be other numbers corresponding to the ID100, or may be a specific location for which the ID100 is provided, such as XX hotel, XX district XX city, etc.
In this step, for the plurality of primary directories determined in step 202, for the same primary directory, in the data associated with the primary directory, according to the acquisition time indicated by the time information of all associated data and a preset time interval, a plurality of secondary directories corresponding to the primary directory are determined, and the data and the corresponding secondary directories are associated according to the time information.
Here, the time interval division may be multiple acquisition times of multiple data associated with the same primary directory, an earliest acquisition time and a latest acquisition time may be determined, and a time interval is determined by using the earliest acquisition time as a start time and the earliest acquisition time as an end time, on the basis of which time division is performed; or a preset time interval, such as 24 hours a day or a worship, a collection time period, etc.
Here, the determination of the time interval may be determined according to the requirement of the data refinement degree, and may be a time interval of one day, or may be a time interval of 10 minutes if the time requirement is more detailed time division.
In the step, a storage data path in a format of primary directory-secondary directory-data ID is generated according to the secondary directory associated with each piece of data, the primary directory to which the secondary directory belongs and the data identification information corresponding to the data.
Here, after the secondary directory of the data is generated according to the time information, the tertiary directory may be subdivided again according to the ID of the data, and the secondary directory may be further distinguished by performing hash modulo according to the ID of the data.
For example, the location identification information of a piece of data indicates that the location identification is 100, the time information indicates that the collection time is 2019-08-1419:05, the ID of the piece of data is 001, and in the location partition for the location identification of 100, the time interval of the time partition is one day, then it can be known that the secondary catalog corresponding to the piece of data is 20190814, and then the storage path of the piece of data is 100 plus 20190814 plus 001.
Referring to fig. 3 and 4, fig. 3 is a data schematic diagram of the number stored in the database, the data stored in the database stores the data identifier (data ID) of the data, the location ID corresponding to each piece of data, and the acquisition time of the data, and for three pieces of data with a location ID of 100, the acquisition time of data with an ID of 001 is 2019-08-1416: 05:10, the acquisition time of data with an ID of 002 is 2019-08-1416: 35:20, and the acquisition time of another data with an ID of 001 is 2019-08-1418: 55: 50; for three pieces of data with the place ID of 101, the collection time of data with the ID of 001 is 2019-08-1417: 05:10, the collection time of data with the ID of 002 is 2019-08-1418: 35:20, and the collection time of the other data with the ID of 001 is 2019-08-1419: 55: 50. Fig. 4 is a schematic diagram of a data division directory, in which an area 3A is a divided directory, and an area 3A is a primary directory: region slices 100 and 101; area 3b is a secondary directory: time- slices 2019081416, 2019081418, 2019081417, 2019081419; area 3c is a tertiary directory: and D, ID fragmentation.

Referring to fig. 5, fig. 5 is a flowchart of a method for generating a data storage path according to another embodiment of the present application. As shown in fig. 5, a method for generating a data storage path according to an embodiment of the present application includes:
step 501, obtaining a plurality of pieces of data, and location identification information and time information corresponding to each piece of data.
Step 502, determining a plurality of primary catalogs corresponding to the plurality of pieces of data based on the location identification information of each piece of data, and associating each primary catalog with at least one corresponding piece of data;
step 503, for each primary catalog, determining a plurality of secondary catalogs corresponding to the data associated with the primary catalog based on the acquisition time determined by the time information of each piece of data associated with the primary catalog and a preset time interval, and associating each secondary catalog with each piece of data.
Step 504, generating a data storage path corresponding to each piece of data based on the secondary directory associated with each piece of data, the primary directory to which the secondary directory belongs, and the data identification information of each piece of data.
And 505, determining a query primary catalog corresponding to the query place identification information and a query secondary catalog corresponding to the query time information based on the obtained query place identification information and the query time information.
In the step, based on the obtained query information, a query primary catalog corresponding to the query location identification information in the query information is determined according to the query location identification information and the query time information in the query information, and a query secondary catalog is determined according to the query time information in the query information.
Here, the index can be used for data query, and to design an index structure, the following requirements need to be satisfied: 1) the length of the index occupied bytes is consistent: aiming at different space-time trajectory types, the length of the finally designed index byte should be consistent (because only consistent, an efficient search algorithm is convenient to use in subsequent index search); 2) the index occupies as few bytes as possible: the purpose is to reduce the space problem of index storage (because after the combination explosion, the relation storage should be compressed); 3) the index can be quickly positioned to the original space-time track record: the index merely provides a search for spatiotemporal trajectory records, and particularly uses spatiotemporal trajectory data to complete the computation of the relationship. In the index structure, specific bytes may be set to store specific query location information and query time information, for example, one byte is used to store query location information, eight bytes are used to store query time information, and the like.
Step 506, determining a matched data storage path based on the query primary directory and the query secondary directory, and determining data corresponding to the data storage path as query target data.
In the step, a data storage path including a query primary directory and a query secondary directory is determined from all data storage paths, data corresponding to the data storage path is determined as query target data of the query, and the query target data is taken out so as to facilitate subsequent data processing.
For example, the data query information indicates that the third data is to be queried when 16:00 pm in 14 th of 08 th of 2019 on the train, the location identifier corresponding to the train is 120, the data storage path corresponding to the third data is 120-2019081416-003, the data under the path is found, and one data query is completed.
The descriptions of step 501 to step 504 may refer to the descriptions of step 201 to step 204, and the same technical effects can be achieved, which is not described in detail herein.
Further, step 502 further includes: dividing data of the same place identification information in the obtained plurality of pieces of place identification information into a same place identification information set; selecting any place identification information from the place identification information set, and determining the place identification information as a primary catalog corresponding to the place identification information set; and associating all data contained in the place identification information set with the primary catalog corresponding to the place identification information set.
In the step, after a plurality of pieces of data are obtained, for the location identification information of each piece of data, the data having the location identification indicated by the same location identification information are divided into the same location identification information set, the location identification indicated by the location identification information corresponding to each piece of data in the location identification data set is determined as the identification of the location identification data set, the number of the location identification data sets is determined as the number of primary catalogs, the location identification corresponding to each location identification data set is used as a primary catalog, and all the data in the location identification data set are associated with the primary catalog corresponding to the location identification data set to which the data belong.
For example, if six pieces of data are acquired, the location id of a indicated by the location identification information of a is 100, and the location id of B indicated by the location identification information of B is 101; the location identification of C indicated by the location identification information of C is 100; the location identification of D indicated by the location identification information of D is 101; the location identification of E indicated by the location identification information of E is 102; the location identification of F indicated by the location identification information of F is 101. Then, according to the location identifications indicated by the location identification information corresponding to the six pieces of data, three location identification data sets can be determined, and the data identifications (primary catalog) corresponding to each location identification data set are respectively 100, 101 and 102; the data A and the data C in the place identification data with the data identification of 100 are associated with the primary catalog of 100; associating data B, data D and data F in the place identification data set with the data identification 101 with a primary catalog with the primary catalog being 101; data E in the location identification dataset with data identification 102 is associated with a primary directory with primary directory 102.
Further, a plurality of secondary directories corresponding to the data are determined by the following steps: aiming at the same primary catalog, acquiring a plurality of acquisition times of a plurality of data associated with the primary catalog; dividing the time interval to which the plurality of acquisition times belong into a plurality of sub-time intervals based on the preset time interval; and acquiring the starting time of each sub-time interval, and determining the starting time of each sub-time interval as a corresponding secondary directory.
