Description
Technical Field
The present application relates to the field of data migration technologies, and in particular, to a data migration method and a terminal.
Background
With the development of mobile phone technology, the performance of mobile phones affects the user experience. In order to meet the requirements of mobile phone use, a user can replace the mobile phone with the update of the mobile phone. The replaced mobile phone is not limited to a brand new mobile phone, mobile phone data such as short messages, contacts and call records which need to be reserved by a user may be stored in the replaced mobile phone, and mobile phone data on an old mobile phone need to be reserved by the user. Therefore, after the new mobile phone is replaced, in order to not affect the use of the user, the mobile phone data stored on the old mobile phone needs to be imported into the new mobile phone and merged with the original mobile phone data of the old mobile phone.
In the conventional technology, after a user replaces a mobile phone, a user usually uses a key-press software to transfer mobile phone data of the old mobile phone to a new mobile phone. The mobile phone data is stored in the mobile phone in a database mode, when the mobile phone is changed, the database corresponding to the mobile phone data on the old mobile phone is backed up firstly, then the backup database is transmitted to the new mobile phone, and then the mobile phone data in the backup database is inserted into the database of the new mobile phone. When the mobile phone data in the backup database is inserted into the new mobile phone database, the mobile phone data in the backup database is generally added to the database of the new mobile phone one by one. For example, 10000 pieces of short message data in the backup database need to be inserted into a new mobile phone database 10000 times, and it is very time-consuming to insert one piece of short message data into the database.
In order to solve the above problems, the prior art provides a scheme that a backup database is divided into a plurality of asynchronous queues, and the asynchronous queues are used for simultaneously inserting mobile phone data into the database. As shown in fig. 1, also taking 10000 pieces of short message data as an example, if 10 pieces of short message data can be stored in one asynchronous queue, 3 asynchronous queues are set, and the short message data is inserted into the 3 asynchronous queues at the same time, but the short message data is still the short message data in one operation backup database. And in order to ensure the normal insertion of the short message data, the crash can not occur, and the number of the asynchronous queues is limited. Although the speed of transferring the short message data by adopting the asynchronous queue is higher than that of inserting the short message data one by one in the prior art, when a large amount of short message data is stored, a long time still needs to be consumed.

Detailed Description
In order to make the technical solutions in the embodiments of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application are further described in detail below with reference to the accompanying drawings.
Example one
Fig. 2 is a schematic flow diagram of a data migration method according to an embodiment of the present application, and referring to fig. 2, the data migration method according to the embodiment of the present application includes:
s101, receiving the backup database.
In this embodiment, the first terminal is a terminal device that receives migration data, and the second terminal is a terminal device that migrates data. The backup database is generated by backing up the database of the second terminal. The data types in the databases of the first terminal and the second terminal may include short messages, contacts, call records, and the like. The backup database generated from the database backup of the second terminal may also comprise a plurality of databases, wherein the type of data in each backup database is unique. For example, 10 contacts, 30 messages and 40 call records, 10 pieces of contact data are stored in a backup database, the data type stored in the backup database is a contact, and correspondingly, 30 pieces of message data and 40 pieces of call record data are also stored in the corresponding backup databases respectively.
When data in the database of the second terminal needs to be migrated into the database of the first terminal, the data migration cannot be directly realized because the first terminal and the second terminal are two independent devices. In this embodiment, the first terminal may establish a connection with the second terminal through one identification identifier, so as to implement data transmission, and further enable the first terminal to receive the backup database stored on the second terminal.
Specifically, the identification mark in this embodiment may be a two-dimensional code. As shown in fig. 3, the first terminal obtains an IP address after establishing a WLAN hotspot by itself, sets a Port and a Service Set Identifier (SSID) of the WLAN according to the allocated IP address, and obtains a WLAN access point by using a character string "IP: port: and in the SSID mode, generating a corresponding two-dimensional code picture, and waiting for the second terminal to scan. The second terminal scans the two-dimensional code of the first terminal, then is automatically connected to the WLAN hotspot of the first terminal, establishes data connection with the first terminal, transmits the backup database to the directory appointed by the first terminal after establishing data connection, and the first terminal obtains the transmitted backup database from the appointed directory. Of course, in this embodiment, the second terminal may also generate a two-dimensional code, and the first terminal scans the two-dimensional code of the second terminal to establish a data connection between the first terminal and the second terminal, which is not described in detail again.
S102, if the database of the first terminal is not empty, comparing the number of the data in the database of the first terminal with the number of the data in the backup database.
In this embodiment, if the first terminal is a used terminal, the database of the first terminal may not be empty, and there is data.
In general, when the current user uses the first terminal used by another user, the data in the first terminal is irrelevant to the current user and can be deleted. However, there may also be cases where the data in the first terminal database needs to be retained. For example, there are user a, user B, and user C. The user A gives the used first terminal to the user B, and the first terminal of the user A stores data such as the contact way, the call record and the short message content of the user C. For the user B, the contact information, the call record, the short message content, and the like of the user C stored in the first terminal need to be retained, and at this time, the data in the database of the first terminal needs to be retained.
When the database of the first terminal is determined to be not empty and the data in the database of the first terminal needs to be reserved, the number of data in the database of the first terminal and the number of data in the backup database need to be respectively obtained, and then comparison is carried out to determine the database with a large number of data. S103, if the number of the data in the database of the first terminal is less than that of the data in the backup database, inserting the data in the database of the first terminal into the backup database.
According to the method in the conventional technology, data in the backup database is inserted into the database of the first terminal one by one, and if the number of data in the database of the first terminal is more than that of the backup database, the number of data in the database of the first terminal is more at the moment, the data can be inserted into the database of the first terminal according to an asynchronous queue, and the data in the backup database is inserted into the database of the first terminal.
However, if the number of data in the database of the first terminal is less than the number of data in the backup database, the data in the backup database is more. It takes a lot of time if the data in the backup database is inserted into the database of the first terminal one by one. In view of the above situation, in the embodiment of the present application, data in the database of the first terminal is inserted into the backup database, a field position corresponding to the data inserted into the database of the first terminal in the backup database is first determined, and the data in the database of the first terminal is inserted into the backup database according to the field position.
In an exemplary embodiment, if the number of data in the database of the first terminal is 100, and the number of data in the backup database is 10000, if the conventional data migration method is adopted, 10000 of data in the backup database need to be inserted into the database of the first terminal in terms of pieces, and the number of insertion times is 10000. However, by using the data migration method of the embodiment, 100 pieces of data in the database of the first terminal are inserted into the backup database, and the number of the data in the database of the first terminal is 100, so that only 100 times of insertion is needed, and compared with 10000 times of data insertion in the conventional method, 9900 times of data insertion operation is saved, and further, the data migration time is shortened.
As can be seen from S101, the data type stored in the backup database in this embodiment may be a short message, a contact, or a call record. According to different types of data stored in the backup database, the method for determining the field position corresponding to the data in the database of the first terminal inserted in the backup database in the embodiment is also different.
If the data type of the memory number in the backup database is the short message, respectively acquiring the receiving time corresponding to the short message data in the backup database and the short message data in the database of the first terminal, and determining the field position corresponding to the short message data inserted into the database of the first terminal in the backup database according to the sequence of the receiving time.
For example, there are 10 pieces of short message data in the backup database, the corresponding receiving times are t1 and t2 … t10, respectively, and t1 to t10 are arranged in chronological order. And two pieces of short message data exist in the database of the first terminal, the corresponding receiving time is T1 and T2, and T1 is between T1 and T2 according to the receiving time sequence, T2 is after T10, and finally the short message data insertion field position with the receiving time of T1 in the database of the first terminal is determined to be the position between the two pieces of short message data corresponding to the receiving time of T1 and T2 in the backup database, and the short message data insertion field position with the receiving time of T2 in the database of the first terminal is the position after the short message data corresponding to the receiving time of T10 in the backup database.
And if the data type of the number stored in the backup database is a contact, respectively acquiring the contact data in the backup database and the first surname of the contact in the contact data in the database of the first terminal, and determining the field position corresponding to the contact data inserted into the database of the first terminal in the backup database according to the arrangement sequence of the first surname.
For example, there are 5 contact data in the backup database, and the corresponding initials of the last names are a, b, d, h, and w, respectively. And if two pieces of contact data exist in the database of the first terminal, and the corresponding surname initials are c and f, the position of the contact data insertion field with the surname initials of c in the database of the first terminal is finally determined to be the position between the two pieces of contact data corresponding to the surname initials b and c in the backup database, and the position of the contact data insertion field with the surname initials of f in the database of the first terminal is the position between the two pieces of contact data corresponding to the surname initials d and h in the backup database.
If the data type of the number stored in the backup database is the call record, respectively acquiring the start time of the call record data in the backup database and the call record data in the database of the first terminal, and determining the field position corresponding to the call record data inserted into the database of the first terminal in the backup database according to the arrangement sequence of the start time.
For example, there are 10 pieces of call record data in the backup database, the corresponding start times are t1 and t2 … t10, respectively, and t1 to t10 are arranged in the chronological order of the start times. And two pieces of call record data exist in the database of the first terminal, the corresponding starting times are respectively T1 and T2, and the T1 is between T1 and T2, and the T2 is between T9 and T10 according to the starting time sequence. The location of the call record data insertion field with the start time of T1 in the database of the first terminal is finally determined as the location between two pieces of call record data corresponding to the start times of T1 and T2 in the backup database, and the location of the call record data insertion field with the start time of T2 in the database of the first terminal is determined as the location between two pieces of call record data corresponding to the start times of T9 and T10 in the backup database.
It should be noted that the above method for determining the field insertion position of the data in the database of the first terminal in the backup database is only illustrative, and the present application is not specifically limited, and other manners may also be adopted, which is not described again here.
And S104, covering the database of the first terminal with the backup database.
After the data in the database of the first terminal is inserted into the backup database, the data in the database of the first terminal and the data in the database of the second terminal simultaneously exist in the backup database. After the backup database is controlled to cover the database of the first terminal, although the data in the database of the first terminal is covered, the original data in the database of the first terminal exists in the backup database at the moment, so that the data in the database of the first terminal cannot be lost.
As can be seen from the foregoing embodiments, the present application provides a data migration method, when the database of the first terminal is not empty, and the number of data in the database of the first terminal is less than the number of data in the backup database, compared with the case where data in the backup database is inserted into the database of the first terminal, the number of data insertion times is reduced, and further, the time for inserting data is reduced.

Example two
In a first embodiment, a first terminal is a terminal used by a user, and this embodiment provides another data migration method for a case where the first terminal is a brand-new terminal and a database of the first terminal is empty, with reference to fig. 5, where the method includes:
