下面將結合本發明實施例中的附圖，對本發明實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅是本發明一部分實施例，而不是全部的實施例。基於本發明中的實施例，本領域普通技術人員在沒有做出進步性勞動前提下所獲得的所有其他實施例，都屬於本發明保護的範圍。
下面參考本發明的若干代表性實施方式，詳細闡釋本發明的原理和精神。
雖然本發明提供了如下述實施例或附圖所示的方法操作步驟或裝置結構，但基於常規或者無需進步性的勞動在所述方法或裝置中可以包括更多或者更少的操作步驟或模組單元。在邏輯性上不存在必要因果關係的步驟或結構中，這些步驟的執行順序或裝置的模組結構不限於本發明實施例或附圖所示的執行順序或模組結構。所述的方法或模組結構的在實際中的裝置或終端產品應用時，可以按照實施例或者附圖所示的方法或模組結構進行順序執行或者平行執行。
下面介紹本發明的具體技術方案。
傳統的行動端NoSQL資料庫，如realm、objectbox的索引建立和關係查詢均是基於自己的資料庫特定實現，不具備通用性。基於此，在本發明提供了一種基於行動端NoSQL資料庫的索引建立方法，如圖1所示，該方法包括：
步驟101：根據NoSQL資料庫中預存資料的屬性設置索引資訊；
步驟102：根據相應屬性的預存資料的類型，確定將與相應屬性相對應的索引資訊存入數值型索引儲存結構或字元型索引儲存結構中；
步驟103：將NoSQL資料庫的位址、數值型索引儲存結構的位址和字元型索引儲存結構的位址儲存在NoSql連接池中。
在本發明的一種實施方式中，本發明通過注解 (Annotation)來設置索引資訊，這樣做的目的是方便應用層設置索引資訊，對NoSQL資料庫中的原有邏輯無侵入。
在本發明的一種實施方式中，針對數值型索引排序與字元型索引排序的規則不同(後者是字典序)，本發明建立了雙索引儲存結構：數值型索引儲存結構和字元型索引儲存結構。在為NoSQL資料庫建立索引時，需要分析其中的預存資料屬於數值型還是字元型。比如，當預存資料為人的資訊時，其資料屬性可以是年齡、姓名、身高、體重等等。針對資料屬性是年齡、身高、體重等，其資料類型屬於數值型，針對資料屬性是姓名時，其資料類型屬於字元型。數值型索引儲存結構和字元型索引儲存結構需要分開儲存。
在本發明的一種實施方式中，現有的NoSQL資料庫中一般存在字元型索引排序，不存在數值型排序，因此，本發明會將與相應屬性相對應的索引資訊進行排序處理(此處所指的是數值型排序)，獲得排序處理後的索引資訊，然後步驟102具體按照如下執行：將排序處理後的索引資訊存入數值型索引儲存結構或字元型索引儲存結構中。其中對數值型索引進行排序處理的目的是防止類似“10”小於“2”的情況發生，也就是說不添加數值型排序，會根據字元型排序處理，此時會出現“10”小於“2”的情況。由於索引採用有序結構，使得OrderBy這樣的複雜排序時間複雜度達到O(N)。整個索引建立方法無需侵入底層資料庫實現以及應用層實現，使得本索引建立方法具有強大的可移植性。
在本發明的一種實施方式中，本發明通過NoSql連接池(Connection Pool)來管理多個NoSql實例，從而方便索引的儲存。
基於同一申請構思，本發明還提供了一種基於行動端NoSQL資料庫的索引建立裝置，如下面的實施例所述。由於基於行動端NoSQL資料庫的索引建立裝置解決問題的原理與基於行動端NoSQL資料庫的索引建立方法相似，因此基於行動端NoSQL資料庫的索引建立裝置的實施可以參見基於行動端NoSQL資料庫的索引建立方法的實施，重複之處不再贅述。以下所使用的，術語“單元”或者“模組”可以實現預定功能的軟體及/或硬體的組合。儘管以下實施例所描述的裝置較佳地以軟體來實現，但是硬體，或者軟體和硬體的組合的實現也是可能並被構想的。

Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making progressive labor fall within the protection scope of the present invention.
The principle and spirit of the present invention will be explained in detail below with reference to several representative embodiments of the present invention.
Although the present invention provides method operation steps or device structures as shown in the following embodiments or drawings, the method or device may include more or less operation steps or modes based on conventional or no progressive labor. Group unit. In steps or structures where there is no necessary causality in logic, the execution order of these steps or the module structure of the device is not limited to the execution order or module structure shown in the embodiments of the present invention or the drawings. When the actual method or module structure is applied to an actual device or terminal product, the method or module structure shown in the embodiments or drawings may be executed sequentially or in parallel.
The specific technical solutions of the present invention are described below.
Traditional mobile NoSQL databases, such as realm and objectbox index creation and relational queries, are based on their own database-specific implementations and are not universal. Based on this, the present invention provides an index creation method based on the mobile NoSQL database. As shown in FIG. 1, the method includes:
Step 101: Set index information according to the attributes of the pre-stored data in the NoSQL database;
Step 102: According to the type of the pre-stored data of the corresponding attribute, determine to store the index information corresponding to the corresponding attribute in the numeric index storage structure or the character index storage structure;
Step 103: Store the address of the NoSQL database, the address of the numeric index storage structure, and the address of the character index storage structure in the NoSql connection pool.
In one embodiment of the present invention, the present invention sets the index information through annotations. The purpose of this is to facilitate the application layer to set the index information without intruding into the original logic in the NoSQL database.
In an embodiment of the present invention, for numerical index sorting and character index sorting rules are different (the latter is a lexicographic order), the present invention establishes a dual index storage structure: a numeric index storage structure and a character index storage structure. When creating an index for a NoSQL database, you need to analyze whether the pre-stored data is numeric or character. For example, when the pre-stored data is human information, the data attributes may be age, name, height, weight, etc. For the data attribute is age, height, weight, etc., the data type is numeric, and for the data attribute is the name, the data type is character type. The numeric index storage structure and the character index storage structure need to be stored separately.
In one embodiment of the present invention, the existing NoSQL database generally has character index sorting, and there is no numerical sorting. Therefore, the present invention will sort the index information corresponding to the corresponding attributes (referred to here as Is numeric sorting), and the sorted index information is obtained, and then step 102 is specifically executed as follows: storing the sorted index information in a numeric index storage structure or a character index storage structure. The purpose of sorting numerical indexes is to prevent situations like "10" being less than "2". That is to say, if numerical sorting is not added, sorting will be performed according to the character type. At this time, "10" is less than " 2" situation. Because the index uses an ordered structure, the time complexity of complex sorting such as OrderBy reaches O(N). The entire index establishment method does not need to invade the underlying database implementation and application layer implementation, which makes the index establishment method have strong portability.
In one embodiment of the present invention, the present invention manages multiple NoSql instances through a NoSql connection pool (Connection Pool), thereby facilitating the storage of indexes.
Based on the same application concept, the present invention also provides an index building device based on the mobile NoSQL database, as described in the following embodiments. Since the principle of solving problems with the indexing device based on the mobile NoSQL database is similar to the indexing method based on the mobile NoSQL database, the implementation of the indexing device based on the mobile NoSQL database can be found in the mobile terminal based on the NoSQL database. The implementation of the index establishment method will not be repeated here. As used below, the term “unit” or “module” can be a combination of software and/or hardware that can realize a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation of hardware or a combination of software and hardware is also possible and conceived.

Step 302: Find corresponding index information from the numeric index storage structure and/or the character index storage structure according to the query condition;
Step 303: Obtain the address of the NoSQL database from the NoSql connection pool according to the index information;

In an embodiment of the present invention, step 302 specifically includes:
Determine the attributes and types of the query conditions;
The corresponding index information can be found from the numeric index storage structure and/or the character index storage structure according to the attributes and types of the query conditions.
