C. after receiving the Query Information of the value that comprises described querying condition, from tables of data, obtain the pairing record identification of the database information that meets this Query Information according to described value, and the record identification obtained formed record identification collection more than or equal to one, inquire about the tables of data at each record identification centralized recording sign place according to the internal memory concordance list, from tables of data, obtain the database information of record identification correspondence, and all database informations that each record identification set pair is answered send to the user respectively.
Among the described step c, concentrate the database information of all record identification correspondences to be kept in the packet record identification, and this packet is sent to the user.
This method may further include, the mutual database management module (DBDaemon) of setting and user and database in database is then set up the internal memory concordance list of preserving database information record identification and tables of data identification information corresponding relation by DBDaemon among the step b; Among the described step c, by DBDaemon receive Query Information, obtain record identification and generate the record identification collection, from the internal memory concordance list query note sign place tables of data, obtain the database information of record identification correspondence, and database information is sent to the user.
Time according to every database information input database is that every database information is provided with record identification.
Among the described step b, the number of the record identification that the record identification collection comprised is set according to the volume of transmitted data of network and the data volume that is kept at the information in the tables of data.
Among the described step a, set up tables of data according to the unit interval, among the described step b, all database informations were kept at respectively in the corresponding tables of data according to the unit interval.
The described unit interval is one day.
Described database is the short message data storehouse.
The present invention program has following beneficial effect:
1) by a plurality of tables of data are set for database, all information is kept at respectively in these tables of data, can improves inquiry velocity, and be convenient to deposit tables of data in database the database of big data quantity;
2) be divided into a plurality of record identification collection by the record identification that will obtain, the maximum transmitted amount that makes database can make full use of network is transmitted details;
3) be used to preserve the internal memory concordance list of the corresponding relation of tables of data and record identification by foundation, foundation is to the index copy of entire database, make database obtain the tables of data at institute information inquiring place by this internal memory concordance list, and realization is to the scanning of all tables of data in the database, so that from tables of data, obtain database information apace, further improved inquiry velocity to the database of big data quantity.
Description of drawings
Fig. 1 is the realization flow figure of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and the specific embodiments the present invention program is described in further detail.
With the example that is treated to the short message data storehouse, referring to Fig. 1, the present invention program realizes by following steps:
For reducing when obtaining the short message details to the required time of short message data storehouse scanning, a plurality of tables of data need be set, and unique identification information is set for each tables of data correspondence, the details of short message are kept in these tables, the short message details can comprise the calling and called address information, submit to and issue the time, mobile switching centre (MSC) address, encoding scheme and type etc., when the short message details are saved in tables of data, also need a unique record identification be set at every short message, and this record identification is kept in the short message data storehouse with the short message details, this record identification can be set to increase in proper order according to the short message entry time.When tables of data is set, can be for a tables of data be set every day, this tables of data writes down all short message details on the same day, and the short message details can deposit in the tables of data successively according to its time that is submitted to database.
This DBDaemon interface need be set up an internal memory concordance list, and this internal memory concordance list is kept in the internal memory.The corresponding relation of keeping records sign and tables of data in this internal memory concordance list.Such as, comprise in the tables of data that record identification is 1 to 10 short message, this tables of data be designated a, then preserve the corresponding relation of this tables of data a and record identification 1 to 10 in the internal memory concordance list.
The querying condition of user's input can comprise information such as caller phone number and fixed time section, if comprise the fixed time section in the querying condition, then the DBDaemon interface inquires the pairing record identification of the short message that meets this querying condition from the pairing tables of data of this fixed time section, such as, it is that 12345 cellphone subscriber is in July 1 that the user needs the inquiring calling number, 2, the details of three days on the 3rd the short message that is sent, then the user sends to the DBDaemon interface with cell-phone number and date, after the DBDaemon interface is received Query Information, from the short message data storehouse with July 1,2, obtained the record identification of the short message correspondence of 12345 users transmission in the corresponding tables of data on the 3rd; If there is not the fixed time section in the querying condition, then the DBDaemon interface need inquire the pairing record identification of the short message that meets this querying condition from all tables of data, such as, it is the details of 12345 the short message that the cellphone subscriber sent that the user needs the inquiring calling number, then the user sends to the DBDaemon interface with cell-phone number, and the DBDaemon interface obtains the record identification of the short message correspondence of 12345 users transmission from all tables of data in short message data storehouse.
In general, the data volume of the information that the user need obtain is bigger, and present agreement has been stipulated data quantity transmitted in the network, therefore DBDaemon possibly can't directly send to the user with all data that inquire, and, user place network allows often also little than the agreement regulation of the data volume that once sends, and at this situation, the present invention program adopts DBDaemon that the pairing short message information of record identification is transferred to the user several times.All record identifications of the user inquiring condition that meets that DBDaemon at first will obtain in step 103 are divided into several record identification collection, and respectively each record identification collection are handled.Specifically, because the size of data of each short message information is similar, therefore can be according to the size of every short message information and the maximum transmission data amount of network, all record identifications are divided into a plurality of record identification collection, and pairing all the short message details of each record identification collection can once transfer out by network.When the record identification collection is handled, at first judge the tables of data at concentrated each the record identification place of this record identification according to the internal memory concordance list, from this tables of data, obtain the short message details, and the short message details of obtaining are kept in the packet.After the short message details of obtaining concentrated all the record identification correspondences of this record identification, the packet of preserving these short message details is sent to the user.
Below only be preferred embodiment of the present invention, not in order to restriction protection scope of the present invention.
