The embodiment of the invention provides an information query method based on a Redis database, which is shown in a flow chart of the information query method based on the Redis database shown in FIG. 1 and is executed by a server, and the method comprises the following steps S102 to S106:
step S102: and receiving an information inquiry application sent by a user terminal.
The user terminal may be a mobile terminal (e.g., a mobile phone, a tablet computer, etc.) or a computer terminal, the information query application may be an application for querying a score, or may also be a query report (e.g., a physical examination report) or other application for information related to the user, the information query application is sent to a server by the user terminal, and the server receives the information query application sent by the user terminal by using a Redis database interface.
Step S104: and acquiring target information matched with the information query application according to the information query application and the pre-established information list in the Redis database and the sorting index of the information list.
Because the pre-established Redis database stores the information list and the sorting index of the information list, the information which the user wants to query can be obtained according to the information query application of the user, and the information which the user wants to query is obtained from the information list stored in the Redis database as the target information according to the obtained information which the user wants to query.
The Redis database is a high-performance key-value database. The Redis database compensates for the shortage of key/value storage such as memcached to a great extent, and can play a good role in supplementing the relational database.
Step S106: and sending the target information to the user terminal.
And sending the acquired target information matched with the information query application to a user terminal so that the user terminal can display the received target information to a user, and the user can acquire the information to be queried through the display of the user terminal.
According to the information query method based on the Redis database, provided by the embodiment of the invention, the information database does not need to be frequently called, the target information matched with the information query application can be obtained according to the information query application of the user terminal and the information list and the sorting index of the information list in the Redis database, and the Redis database established in advance has the characteristic of ordered set when storing data, so that the step of synchronously counting and sorting the information by the information database is saved, and the information query efficiency is improved.
In order to quickly acquire target information matched with the information query application, the embodiment provides a specific implementation manner for acquiring the target information matched with the information query application according to the information query application and a pre-established sorting index of an information list and an information list in a Redis database: the information query application comprises user registration information, and list sequencing information corresponding to the user registration information is obtained by querying a sequencing index of an information list in a Redis database; and acquiring target information matched with the user registration information from an information list in the Redis database according to the list sorting information corresponding to the user registration information. The user registration information can be user accounts and passwords, the list sorting information can be ranking or position information of the user accounts corresponding to the user registration information in the information list, and each user account is unique, so that target information matched with the user registration information can be quickly acquired from the information list according to the ranking or position information of the user accounts corresponding to the user registration information in the information list.
In a specific embodiment, the building step of the Redis database may be specifically executed with reference to the following steps (1) to (4):
step (1): acquiring specified information from an information database; the information database is used for storing newly released specified information. And when the specified information which the user wants to obtain is stored in the information database, obtaining the specified information from the information database. For example, when the user is a student, the teacher uploads the final student score, which is the newly issued designated information, to the information database through the management terminal, or the staff in the hospital uploads a physical examination report, which is the newly issued designated information, of the user to the information database through the management terminal.
In an embodiment, the manner of acquiring the specific information from the information database may be: and acquiring the specified information from the information database at regular time according to a preset time interval. The preset time interval can be set according to actual conditions, and for example, the preset time interval can be any time length between 1 and 10 minutes. The specific information may be set according to different information queries, for example, when the queried information is a result, the specific information is a user result, when the queried information is a test result, the specific information is a test result, and when the queried information is a physical examination report, the specific information is a physical examination report of the user. The server periodically acquires the specified information from the information database and stores the acquired specified information to a statistical calculation unit in the server.
In another embodiment, the manner of acquiring the specific information from the information database may be: and if the specified information in the information database is monitored to be updated, acquiring the updated specified information from the information database. The server monitors whether the designated information in the information database is updated or not in real time, when new designated information is added into the information database, namely the designated information in the information database is updated (for example, a latest score sheet or a latest physical examination report is added into the information database), the server acquires the updated designated information from the information database, and stores the acquired designated information into a statistical calculation unit in the server.
Step (2): and sequencing the specified information to obtain an information list.
The obtained specifying information is sorted according to a preset rule in the server, where the preset rule is related to the specifying information, and for example, the specifying information may be sorted by using a certain parameter amount in the specifying information as a sorting basis to obtain an information list. In one embodiment, the designation information includes user performance. And taking the user score as a sequencing basis to sequence the specified information to obtain a user score list. The user score list is an information list after ordering the specified information. In another embodiment, the specific information may further include a user physical examination report, and the specific information may be sorted by using the user age or the initial of the user name in the user physical examination report as a sorting criterion, so as to obtain the information list. The statistical sorting process may be executed in a statistical computing unit in a server, in order to improve the computing efficiency, the statistical computing unit in the server may include one or more statistical computing units, and the plurality of statistical computing units may implement parallel processing on the specified information in the information database, thereby improving the statistical sorting efficiency of the specified information.
And (3): and generating a sorting index according to the information list.
The sorting index is a tool for helping to quickly find the specified information in the information list, and the sorting index can be a set of user registration information and sorting related to the specified information or the information query application, for example, the sorting index can be a set of account information of the user registration information and user score ranking, so that score ranking of the account information of the user registration information can be obtained through the sorting index, and then user scores under the score ranking are obtained from the information list according to the score ranking, so that the user scores matched with the user registration information are obtained.
And (4): and establishing a Redis database based on the information list and the sorting index.
And adding the information list and the sorting index of the information list into a Redis database to establish the Redis database. The Redis database can store the information lists after statistical sorting and the sorting indexes of the information lists by using a hash key mode, the storage time of the information lists and the sorting indexes of the information lists in the Redis database can be set according to actual conditions, for example, when the information lists are score lists, a date range for score query can be set, and after the date range is exceeded, the score lists in the Redis database and the sorting indexes of the score lists can be automatically deleted, so that a user cannot query score information.
In practical applications, referring to the performance query method flowchart shown in fig. 2, the performance query performed by the information query method based on the Redis database may be executed by referring to the following steps S202 to S208:
step S202: and acquiring user result information from the information database, and sending the acquired user result information to a statistical storage queue. Wherein, the user achievement information can be periodically acquired from the information database; and whether new user achievement information is added into the information database can be monitored in real time, and when the new user achievement information is added, the new user achievement information is obtained from the information database.
Step S204: and acquiring user result information from the statistical storage queue, sequencing the user result information according to the user results, and acquiring a user result list. The ranking mode of synchronous statistics and calculation results in the prior art is converted into the mode of asynchronous efficient data processing result ranking, and the pressure of an information database is greatly reduced.
Step S206: and storing the user achievement list into the Redis database, and enabling the Redis database to generate a sorting index by utilizing the sorting characteristic of the Redis database.
Step S208: receiving a score query application sent by a user terminal, acquiring a user score matched with the score query application according to the score query application, a user score list and a sequencing index in a Redis database, and sending the user score to a corresponding user terminal. After receiving a score query application sent by a user terminal through a reading interface of the Redis database, the corresponding sorting index can be taken out in a paging mode from the ordered set of the Redis database, and score information (the score information can be a personal score of the user or a user score list where the user is located) required to be checked by the user is obtained through the sorting index and user registration information in the score query application, and data after statistical ranking required by a front-end page is returned. According to the score query method, frequent reading of the information database in a short time is converted into periodic single query of the information database, the user score statistics and ranking are completed and then stored in the Redis database, and the user terminal only needs to read the score list of the sorted numbers in the Redis database, so that the processing efficiency of score query is greatly improved.
