FIG. 2 shows a flow chart of a method for providing data retrieval according to an embodiment of the present invention. The method is applied to a background in communication connection with the front end, the background may be implemented as the electronic device 100, and steps in the method are executed by the processor 102 of the electronic device 100. The front end and the background jointly form a data retrieval system, a user inputs contents to be retrieved on a front end interface, the contents are sent to the background, the background retrieves the data and returns a retrieval result to the front end, and the front end displays the retrieval result to the user. In the embodiment of the present invention, a specific storage manner of the data in the background is not limited, for example, the data may be stored in a database, and may also be stored in a file system (including a local file system and a distributed file system).
In the data retrieval method provided in the embodiment of the present invention, four configurations, that is, an index category configuration, an index policy configuration, and a data object configuration, need to be used, where an index category name is recorded in the index category configuration, an association relationship between an index and an index category is recorded in the index configuration (one or more indexes may be provided under one index category), an association relationship between an index and a data object is recorded in the index policy configuration (one or more data objects may be provided under one index), and an association relationship between a data object and an attribute is recorded in the data object configuration (one or more attributes may be provided under one data object).
In one embodiment, the content of these configurations may be:
index category configuration: indexing the category name;
index configuration: index name, index category name;
and (3) index strategy configuration: index strategy name, index name and data object name;
data object configuration: object name, attribute name.
The above configuration may be implemented as a table in a database, and certainly may also be implemented in the form of a configuration file in some implementations, and hereinafter, for simplicity, it is not assumed that the configuration information is stored in a database in the background, but such assumption should not be considered as a limitation to the scope of the present invention.
The data object may include original data and an object name, which is an abstract representation of the original data, and the attribute may be a description of some feature of the original data, or may be regarded as a custom tag added to the original data, and the attribute should be generally defined according to specific retrieval requirements. An index is a data structure used to speed up the retrieval of data. The index class is used to classify the index, and since data is always accessed through the index, the index class is also a classification of the data.
The above concept is exemplified below. Assuming that there is a file of MP4 to be retrieved, a record with an object name of "file", an object attribute name of "extension" and "file size" may be added to the data object configuration, a record with an index category name of "video" may be added to the index category configuration, a record with an index category name of "MP 4 video file" may be added to the index configuration, and a record with an index name of "MP 4 video file" may be added to the index policy configuration, and an object name of "file" may be added to the index policy configuration. Thus, the establishment of the configuration information for retrieval to the 1.MP4 is completed.
The configuration information can be edited by a user on a front-end interface, is stored in the database after being edited, and is read from the database when in use. Of course, in order to speed up the access speed to these configurations during the retrieval, these configurations may be loaded into the cache at the start of the data retrieval system, and may be subsequently read directly from the cache during the retrieval.
It will be appreciated that these configurations are modifiable by the user at the front end, including additions, deletions or modifications to configuration items. And the background responds to the configuration modification operation made by the user at the front end and updates the corresponding configuration item in the database. If the configuration information is already loaded into the cache, the content in the cache needs to be modified synchronously, so that data inconsistency is avoided.
Now, assume that the data retrieval system has stored data, and the index category configuration, index policy configuration, and data object configuration related to retrieval are configured. Referring to fig. 2, the data retrieval method specifically includes:
step S10: the retrieved content and the index category are obtained from the front end.
The retrieval content is input by the user on the front-end interface and is sent to the background, and the user should also specify the index category when retrieving. Wherein the specified index category should be defined in the index category configuration.
Step S11: the lookup obtains at least one index associated with the index category.
The association relationship between the index category and the index is recorded in the index configuration, but it should be noted that only the description of the association relationship is recorded in the index configuration, the real index category and the index are stored in association with each other at the bottom layer of the data retrieval system, and the index category and the index associated therewith can be obtained through the record in the index configuration.
Step S12: the lookup obtains at least one data object associated with the index.
The association relationship between the index and the data object is recorded in the index configuration, but it should be noted that only the description of the association relationship is recorded in the index policy configuration, the real index and the data object are stored in association with each other at the bottom layer of the data retrieval system, and the index and the data object associated therewith can be obtained through the record in the index policy configuration.
Step S13: the lookup obtains at least one attribute associated with the data object.
The association relationship between the data object and the attribute is recorded in the data object configuration, but it should be noted that only the description of the association relationship is recorded in the data object configuration, the real data object and the attribute are stored in association with each other in the bottom layer of the data retrieval system, and the data object and the attribute associated therewith can be acquired through the record in the data object configuration.
Step S14: and judging whether the attribute matched with the retrieved content exists in the at least one attribute.
The matching in step S14 means that the search condition is satisfied, and may be, for example, an equal condition, an inclusive condition, or the like. Depending on the search content, step S14 may search for each attribute, or may search for a plurality of attributes simultaneously. It should be noted that, the retrieval in the embodiment of the present invention is performed only in the attribute, and is not performed in the data itself, so that the attribute needs to be defined appropriately to adapt to the requirement of the retrieval
Step S15: and if the matched attributes exist, determining the data object as a matched data object and returning the matched data object to the front end for display.
In an implementation mode, after a matched object can be searched, the matched object is returned to a front-end interface for displaying, and the real-time display of the search result is realized. In another embodiment, after a matching data object is retrieved, the matching data object may be cached, retrieval is continued in other data objects until the retrieval is completed, and then all the retrieved matching data objects are returned to the front-end interface for display.
It will be appreciated that in addition to presenting data objects, other information may be presented simultaneously, such as matching attributes of the matching data object or all attributes associated with the matching data object.
Taking the aforementioned example of 1.MP4 as an example, assuming that the retrieval content input by the user in the data retrieval system is "MP 4", the retrieval conditions are equal, and the designated index category is "video", the background first finds the index "MP 4 video file" according to the index category "video", then finds the data object "file" according to the index "MP 4 video file", the specific content of the data object "file" stored at the bottom layer is file 1.MP4, then finds the attribute "extension" and "file size" according to the data object "file", and the specific content of the attribute "extension" stored at the bottom layer is "MP 4", so that the attribute is matched with the retrieval content, the data object corresponding to file 1.MP4 is returned to the front end for display, and the "extension" and "file size" thereof may also be displayed at the same time.
The data retrieval method performs objectification definition on data to be retrieved in data object configuration, and sets the attribute of the data object which is expected to be used for retrieval. The attributes can be regarded as tags of the data objects, and the efficiency of searching among the tags is far higher than that of searching among all data in the prior art, so that the efficient data searching can be realized. Meanwhile, the attribute can be set in a self-defined mode in the configuration of the data object, and the degree of freedom is very high, so that the data can be searched in a multi-dimensional and multi-condition mode. In addition, the data are classified to a certain extent by setting the indexes and the index categories, so that the efficiency of data retrieval is improved, and the user can conveniently classify and manage the data.
In one embodiment of the present invention, before step S10 is performed, data may be stored into the data retrieval system by performing steps S20 through S23 for subsequent retrieval of the data. Referring to fig. 3:
step S20: after the data storage interface is invoked, the data object that comes in as an invocation parameter and at least one attribute associated with the data object are obtained.
The background provides a data storage interface for the outside, and the interface can be called by the foreground or other third-party systems and is used for storing data into the data retrieval system. Note that storing as used herein means that data is under the management of the data retrieval system, and how the data retrieval system stores data at the bottom is not limited.
The parameters of the data storage interface comprise a data object and an attribute desired to be associated with the data object, wherein the data object may also further comprise two parameters, namely the original data of the data object and the object name of the data object.
Step S21: and storing the data object and at least one attribute in association with the relationship in the data object configuration.
First, the data object must be stored, and the data object and the attribute must be actually associated in order to find the attribute through the data object, and the association storage in step S21 means that the real association storage is performed at the bottom of the data retrieval system.
Step S22: and searching and obtaining an index corresponding to the data object from the index policy configuration, and storing the data object and the index in association according to the relation in the index policy configuration.
After storing the data object, the index needs to be actually associated with the data object in order to be able to retrieve the data object by the index. The association storage in step S22 also refers to the actual association storage at the bottom of the data retrieval system.
The index can be automatically generated when configuration information is configured, but the index is a null index at the moment, is not associated with any data object, is associated with the index in the process of storing the data object, and meanwhile, the index data is updated.
Step S23: and searching the index configuration to obtain the index category corresponding to the index, and storing the index and the index category in an associated manner according to the relationship in the index configuration.
After storing the index, in order to find the index by the index category, the index needs to be actually associated with the index category. The associative storage in step S23 is to perform real associative storage at the bottom of the data retrieval system.
After steps S20 through S23 are performed, the data is stored in the data retrieval system while the actual association of attributes, data objects, indexes, and index categories is achieved, at which point the subsequent data retrieval steps may be performed.
