All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The method for saving object attributes provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1, a step flowchart of an object attribute saving method provided by an embodiment of the present application is shown, and as shown in fig. 1, the object attribute saving method specifically may include the following steps:
step 101: and obtaining a target object to be stored and an object attribute corresponding to the target object.
The embodiment of the application can be applied to a scene for storing the object and the object attribute based on the bitmap file.
The target object refers to an object that needs to be stored, and in this example, the target object may be an object such as a user, and specifically, may be determined according to a service requirement, which is not limited in this embodiment.
The object attribute refers to an attribute of a target object, and in this example, the object attribute may be a numerical value, for example, the target object is exemplified by users, the object attribute may be an age attribute, and the like, and the age of each user is a numerical value.
It will be appreciated that the above examples are only examples listed for better understanding of the technical solution of the embodiments of the present application, and are not to be construed as the only limitation of the present embodiments.
When the object and the object attribute are required to be stored, a target object to be stored and the object attribute corresponding to the target object can be obtained.
After the target object to be stored and the object attribute corresponding to the target object are acquired, step 102 is executed.
Step 102: determining a target bitmap file according to the object attribute; the target bitmap file comprises n first bitmap files and one second bitmap file, wherein n is a positive integer greater than or equal to 1.
The target bitmap file refers to a bitmap file (bitmap) for storing the target object and the object attribute of the target object.
In a specific implementation, a bitmap is a Value corresponding to an element marked by a bit, and a Key is the element. Because the Bit is adopted as a unit to store data, the storage space can be greatly saved.
In this example, the target bitmap file may include n first bitmap files for storing object attributes of the target object and one second bitmap file for storing object attribute indication information of the target object, where n is a positive integer greater than or equal to 1.
After the target object to be stored and the object attribute corresponding to the target object are acquired, the target bitmap file may be determined according to the object attribute. The process of determining the target bitmap file may be described in detail in connection with the following specific implementation.
In a specific implementation of the present application, the step 102 may include:
substep A1: and obtaining the target object attribute with the largest attribute value in the object attributes.
In this embodiment, the target object attribute is an object attribute with the largest attribute value in the object attributes, for example, the object attribute includes a user 1, a user 2, and a user 3, where the age of the user 1 is 24, the age of the user 2 is 34, and the age of the user 3 is 12, and in this case, the age attribute corresponding to the user 2 may be taken as the target object attribute.
It will be appreciated that the above examples are only examples listed for better understanding of the technical solution of the embodiments of the present application, and are not to be construed as the only limitation of the present embodiments.
After the target object and the object attribute corresponding to the target object are obtained, the target object attribute with the largest attribute value in the object attributes can be obtained.
After the target object attribute having the largest attribute value among the object attributes is acquired, the sub-step A2 is performed.
Substep A2: and determining the bitmap files of the target number according to the target object attribute and a preset attribute value algorithm, and taking the bitmap files of the target number as the target bitmap files.
The preset attribute value algorithm refers to an algorithm preset by a service person for calculating an attribute value of an object attribute, and in this example, a specific calculation manner of the preset attribute value algorithm may be determined according to a service requirement, which is not limited in this embodiment.
The target number refers to the number of bitmaps for storing the object attribute and the object attribute indicating information of the target object, and in this example, the target number is equal to n+1.
After the target object attribute with the largest attribute value in the object attributes is obtained, a target number of bitmap files may be determined according to the target object attribute and a preset attribute value algorithm, and the target number of bitmap files may be used as the target bitmap files, which may be illustrated in the following table 1.
Table 1:
As shown in table 1 above, the ID may be used to indicate the object identifier of the target object, and in a specific implementation, in the system storage, a corresponding object identifier is allocated for each object, so as to distinguish different objects, and in table 1 above, the ID may be used as the identifier of the object. In this embodiment, the preset attribute value algorithm is a sum value algorithm based on 2 and the angle of bitmap is the power, for example, taking ID as1 as an example, the object attribute value of the object is 1, that is, 2 0. The object with ID 2 has an object attribute value of 6, i.e., 2 1+22. When the attribute value of the maximum object attribute is 13, then 2 0+22+23 may be calculated, where the maximum subscript is 3, that is, the number of bitmaps of the saved object attribute is 4, and one bitmap of the saved object attribute indicating information is added, that is, 5 bitmaps are needed to save the object attribute of the target object and the object attribute of the target object, that is, after knowing the preset attribute value algorithm and the maximum object attribute, the number of bitmap files is determined by means of reverse calculation, and then the bitmap files with the number is used as the target bitmap file.
It will be appreciated that the above examples are only examples listed for better understanding of the technical solution of the embodiments of the present application, and are not to be construed as the only limitation of the present embodiments.
Compared with the scheme that only attribute users can not store attribute values of the attribute users in the prior art, the embodiment of the application can be suitable for scenes in which both users and user values are to be stored.
After determining the target bitmap file from the object properties, step 103 is performed.
Step 103: and determining bitmap identification bits in the target bitmap file according to the object identification of the target object.
The bitmap identification bits refer to bit bits in the target bitmap file that match the object identification of the target object.
After determining the target bitmap file according to the object attribute, the bitmap identification bit in the target bitmap file may be determined according to the object identification of the target object, for example, taking table 1 as an example, where each target object corresponds to an ID, in the target bitmap file, the object identification corresponding to each bit may be indicated in advance, for example, the first bit corresponds to the object identification 1, the second bit corresponds to the object identification 2.
It will be appreciated that the above examples are only examples listed for better understanding of the technical solution of the embodiments of the present application, and are not to be construed as the only limitation of the present embodiments.
After the bitmap identification bits in the target bitmap file are determined according to the object identification of the target object, step 104 is performed.
Step 104: and storing the object attribute based on the bitmap identification bit and the first bitmap file, and storing object attribute indicating information of the target object based on the bitmap identification bit and the second bitmap file.
After the bitmap identification bit in the target bitmap file is determined according to the object identification of the target object, the object attribute of the target object may be saved based on the bitmap identification bit and the first bitmap file, and the object attribute indication information of the target object may be saved based on the bitmap identification bit and the second bitmap file, where the object attribute indication information may be used to indicate whether the attribute value of the target object exists, for example, using table 1 and the user integral described above as an example, when the user has an integral, if there is an integral of the user, 1 may be used as the object attribute indication information, and if there is no integral of the user, 0 may be used as the object attribute indication information.
The embodiment of the application can solve the problem that the bitmap in the prior art has only one storage dimension and is not suitable for storing users and user values by combining a plurality of bitmap files to realize the storage of the objects and the object attributes.
In this embodiment, after the object and the object attribute are saved by the plurality of bitmap files, the operation between the object attributes may be performed, and the operations such as intersection, union, complement, etc. may be performed between the plurality of bitmaps. For example, calculating intersections of three attributes of Bitmap1, bitmap2 and Bitamp, firstly judging bit values corresponding to the same lower label bit of the three bitmaps, if the bit values are all 1, indicating that the user exists in the three bitmaps, and as a result, the lower label bit in the bitmaps is also 1. Conversely, if the lower level of any Bitmap is 0, then the lower level of the resulting Bitmap is set to 0, as shown in Table 2 below:
Table 2:
After the intersection operation is performed on the Bitmap1, bitmap2, bitamp, the obtained Bitmap can be shown in the following table 3:
Table 3:
| Bitmap | 0 | 1 | 0 | 0 | 0 | 0 |

When the object attribute is 2.05, the object attribute may be multiplied by 100 to obtain the adjustment attribute value 205, etc.

The fragments gather the results and then return the results to the coordination node, and the coordination node gathers the results of all fragments and returns the results to the final result of the user. In the query process of each segment, firstly, the query expression is analyzed and a query grammar tree is generated, and the corresponding attributes are respectively queried in the storage medium according to the query grammar tree. If the attribute is a non-numerical attribute, directly returning to the Bitmap; if the attribute is the numerical attribute, returning to BSI, filtering the users meeting the conditions according to the numerical query range, and returning Bimtap results. The query grammar tree performs bit operation on the bitmaps returned by the multiple calculations according to a query operator (intersection/union/complement), and generates a final Bitmap result.
