Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Fig. 1 illustrates a method for storing and retrieving mass data according to an embodiment of the present invention, which includes the following steps:
step 101: generating a first initial character string according to the received retrieval data, wherein the first initial character string is a character string consisting of the initial of each character in the retrieval data;
it should be noted that the retrieval data may be data containing only chinese characters, data containing only english words, or data of a mixture of chinese and english. The first letter of a Chinese character refers to the first letter of the Chinese pinyin for the character, and the first letter of an English word refers to the first letter of the English word. The first initial character string is a character string composed of a plurality of initial letters. When the search data only contains Chinese characters, for example, the search data is "Hebei monitoring resource", and the Pinyin of each character is "he", "bei", "jian", "kong", "zi", "yuan", respectively; respectively taking the first letters 'h', 'b', 'j', 'k', 'z' and 'y' of the Chinese pinyin of each character; the first letters taken out are spliced into a first initial character string "hbjkzy" in order. When the search data contains only english words, the search data is, for example, "monitoring resources"; respectively taking the initial letters'm' and 'r' of each English word; the first letters taken out are spliced in order into a first initial character string "mr". When the search data is the data mixed with chinese and english, the process of generating the first initial character string is similar to the process of generating the first initial character string, and is not described herein again. In order to ensure that the corresponding data resource can be retrieved from the data resource library, the retrieved data is the same as the resource name of the data resource in the data resource library.
Step 102: searching the data resource library according to the first initial character string to obtain a search result, wherein the data resource library stores data resources and a second initial character string in advance, and the second initial character string is a character string formed by the initial of each character in the resource name of the data resources;
it should be noted that the data resource library stores a plurality of data resources, wherein each data resource corresponds to a different resource name, and the second initial character string is generated according to the resource name of the data resource, and the generation process is similar to the aforementioned process of generating the first initial character string according to the search data.
The corresponding data resource can be determined from the second initial character string. And during retrieval, matching the first initial character string with a second initial character string in a data resource library, wherein the data resource corresponding to the second initial character string successfully matched with the first initial character string is a retrieval result. Preferably, the first initial character string and the second initial character string are identical, and the matching is considered to be successful, but not limited thereto. If the data resource is not retrieved, the corresponding retrieval result can be a preset pop-up frame prompt. For example, a dialog box in which words such as "search failed", "related data was not searched", and the like are written is popped up by a pop-up manner.
Preferably, when the data resource is pre-stored in the data resource library, the data resource may be stored in a structure form of a dictionary tree according to the second initial character string. Referring to fig. 2, a schematic diagram of a dictionary tree constructed when data resources are stored in a data resource library. The storage edge corresponding to the node 1 is a, and data resources with resource names of "o" and "pickled" are stored in the storage edge. The node 2 has a corresponding storage edge ab, in which data resources with resource names "dad" and "security" are stored.
Preferably, the data structure may be defined using the following code:
struct Info
{
unsigned long nId；
char acName[128]；
}
struct Node
{
char acEdge [26 ]; // identifying which edges the node has
struct Node pstChildnode; // child nodes of the node
struct Info pArray; // storing resources with the same edge
int nCount; // storing the number of resources with the same edge
}
Step 103: and displaying the retrieval result.
It should be noted that the search result may be presented to the user in the form of a pop-up box, but is not limited thereto.
In the embodiment of the invention, when the retrieval is carried out, the initial character string is generated by utilizing the retrieval data, then the retrieval is carried out in the data resource library which stores the data resource and the corresponding initial character string according to the initial character string, and the time length consumed by the retrieval can be greatly shortened when a large amount of data resources are stored in the data resource library.
In order to facilitate the storage of the data resources in the data resource library, on the basis of the above embodiment of the present invention, in the embodiment of the present invention, the data resource library stores the data resources and the second initial character string through a resource linked list, and all the data resources in the same resource linked list correspond to the same second initial character string.
It should be noted that a plurality of resource linked lists are stored in the data resource library, and each resource linked list stores a different second initial character string and a data resource. Aiming at a resource linked list, at least one data resource and a second initial character string are stored in the resource linked list; when the number of the data resources stored in the resource linked list is one, the stored second initial character string is the initial character string generated according to the resource name of the data resource. When the number of the data resources stored in the resource linked list is multiple, the stored second initial character string is the initial character string generated according to the resource name of one of the multiple data resources, and the generated initial character strings are the same according to the resource names of the multiple data resources.
In order to accurately position the retrieved data resource, on the basis of the above embodiments of the present invention, in the embodiments of the present invention, a first code is further stored in the resource chain table, where the first code is generated according to a preset algorithm and a resource name of the data resource, and the first codes corresponding to different resource names are different;
before the step of retrieving the data repository for retrieval results based on the first initial character string, the method further comprises:
and generating a second code according to the retrieval data and a preset algorithm.
It should be noted that, when a plurality of data resources are stored in the resource linked list, in order to distinguish different data resources and accurately locate the retrieved data resources, each data resource or resource name in the resource linked list also corresponds to a different first code. The first code is stored in correspondence with the data resource. Namely, the plurality of first codes correspond to the plurality of data resources one to one, and all the first codes are different. That is, when each data resource is stored, a first code corresponding to the data resource is also stored. The first code is generated according to the resource name of the corresponding data resource and a preset algorithm. The preset algorithm is a fixed algorithm, and as long as the resource names are the same, the first codes calculated according to the preset algorithm are also the same.
Preferably, the step of the data resource library storing the data resource and the second initial character string in advance includes:
acquiring a resource name of a data resource;
generating a second initial character string and a first code according to the resource name and a preset algorithm;
and storing the data resources with the same second initial character string in the same resource linked list, and storing the corresponding second initial character string and the first code.
Specifically, when the number of the data resources is multiple, for each data resource, a corresponding second initial character string and a corresponding first code are generated, and then multiple second initial character strings and multiple first codes are generated. And storing the data resources with the same second initial character string in the same resource linked list, and correspondingly storing the first code during storage.
As shown in fig. 3, on the basis of the foregoing embodiments of the present invention, in the embodiments of the present invention, the step of retrieving the data repository according to the first initial character string to obtain the retrieval result includes:
step 301: determining a target resource linked list according to the first initial character string, wherein the second initial character string in the target resource linked list is the same as the first initial character string;
it should be noted that the data resources in the data resource library are stored in the form of resource linked lists, and each resource linked list has a different second initial character string, so when the second initial character string in a certain resource linked list is retrieved to be the same as the first initial character string, the resource linked list is determined to be the target resource linked list. When the data resource library stores the data resources in the structure form of the dictionary tree, the initial character string of the resource name is stored as the data resource of the first initial character string under the target node determined according to the first initial character string.
Step 302: inquiring the target resource linked list according to the second code to obtain the target data resource, wherein the first code corresponding to the target data resource is the same as the second code;
it should be noted that the first code and the second code are both generated by a preset algorithm.
Step 303: and taking the target data resource as a retrieval result.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
