Fig. 3 is the schematic flow sheet of the method for the database access of the present invention.With reference to figure 3, according to a kind of number of the present invention
The method accessed according to storehouse, comprises the following steps：
Step 301：Database access request is received, mark and the visit of application program are carried in the database access request
Type information is asked, the access type includes reading type and writes type；
It should be noted that in Android (Android) operating system, using SDB databases (SQLite Data
Base) data of application program are stored.In the prior art when application program operates to SDB databases, call
Content provider (ContentProvider) interface, by ContentProvider interface interchange SqliteOpenHelper interfaces
With operation of the realization to database, (SQLiteOpenHelper is a help class of SDB databases, for managing the wound of data
Build and version updating).
When multiple applications initiate write access operation to database, pass through Uniform Resource Identifier (Uniform
Resource Identifier, URI) inquired about in active manager service (Activity Manager Service, AMS)
ContentProvider agent side is fed back into application to corresponding ContentProvider, AMS, bound using passing through
(Binder) call and carry out database access operation, and Binder access maximum upper limit is 16, if it exceeds this upper limit,
Access to database will be blocked.
When multiple applications get when acting on behalf of of ContentProvider, read-write operation can be initiated to database, when same
During Shi Faqi read-write operations, if write operation, only allow a main connection be present；If read operation, can carry out simultaneously
Three strips connect.This mechanism can be prevented to data inconsistency caused by database concurrency access.
Step 302：According to the mark of application program, the priority of process corresponding to acquisition application program；
It should be noted that in low memory management (Low Memory Killer) mechanism of Android, can for it is all enter
Cheng Jinhang classify, as shown in table 1, process corresponding to the application program include local process, Resident Process, prospect process, can
See process, can aware processes, A services, desktop process, B service are gentle deposits into journey, have its oom_ for the process of each classification
The span of adj values, the priority that oom_adj values more Gao Ze represents process are lower.
Table 1
Step 303：The database access request is inserted into the access request queue of pending data storehouse according to priority
In；Wherein, the priority of database access request is higher corresponding to the higher process of priority；The process of equal priority is corresponding
Database access request, the priority for reading the database access request of type is higher than and writes the database access request of type；
Further, the local process, Resident Process, prospect process, visible process, can aware processes, A service, table
Face process, the gentle priority-level for depositing into database access request corresponding to journey of B services arrange from high to low successively.
It should be noted that being directed to same URI inquiry in AMS, enqueue operations are carried out to inquiry request, according to team
Application priority in row carries out dequeue operation, ensures that the high application of priority can get ContentProvider generation
Manage end.When Binder, which reaches, accesses the upper limit, the low URI inquiry requests operation of priority is preferentially discharged, processing priority is high
URI inquiry requests.The progress information (ProcessRecord) in internal memory is saved in AMS, passes through the process number of application
Corresponding oom_adj values in (Process Identification, PID) inquiry ProcessRecord, according to oom_adj values
Order of priority from low to high conducts interviews.
After multiple applications acquire ContentProvider agencies, ContentProvider is according to First Input First Output
The access request in the mode processing data storehouse of (First Input First Output, FIFO), is needed exist for
One is established in ContentProvider and AMS and accesses connection, ContentProvider can pass through AMS inquiry current process
Priority state.A pending data storehouse access request queue is established inside ContentProvider, the queue is according to process
Priority conducts interviews to database, and concrete mode is：When there is new database access request to need to insert pending data storehouse
During access request queue, by the preferential grading of the existing database access request in new database access request and the queue
Row compares, and the priority of database access request is higher corresponding to the higher process of priority；The process of equal priority is corresponding
Database access request, the priority for reading the database access request of type is higher than and writes the database access request of type.
Because during database manipulation, the frequency of read operation is significantly larger than the frequency of write operation, and once-through operation
During, the efficiency of reading is higher than the efficiency write, therefore in the present invention, is visited for database corresponding to the process of equal priority
Request is asked, the priority for reading the database access request of type is higher than the database access request for writing type.
Further, it is described that the database access request is inserted into pending data storehouse access request according to priority
In queue, in addition to：
For the database access request of same process priority and identical access type, according to the nearest of corresponding process
The database access request is inserted into the access request queue of pending data storehouse by usage time, and nearest usage time more connects
Nearly current time, the priority of database access request is higher corresponding to process.
Step 304：The database access request in pending data storehouse access request queue is handled successively；
Further, the database access request in the processing pending data storehouse access request queue, including：If
The processing time for reading the database access request of type exceedes the read time threshold value pre-set, or writes the database visit of type
Ask that the processing time of request writes time threshold more than what is pre-set, disconnect the currently processed database access request, locate
Manage next database access request in pending data storehouse access request queue.
It should be noted that after disconnecting currently processed database access request, it can reduce and break according to actual conditions
The priority for the database access request opened.
Reference picture 4, the embodiment of the present invention additionally provide a kind of mobile terminal 400, and the mobile terminal 400 includes processor
401st, memory 402 and communication bus 403, the processor 401 and the memory 402 are logical by the communication bus 403

The memory is used for data storage storehouse and accesses program；
The processor 401 is used to call the DBAR database access routine stored in the memory 402, and performs following walk
Suddenly：
Database access request is received, the mark and access type letter of application program are carried in the database access request
Breath, the access type include reading type and write type；
According to the mark of application program, the priority of process corresponding to acquisition application program；
The database access request is inserted into the access request queue of pending data storehouse according to priority；Wherein,
The priority of database access request is higher corresponding to the higher process of priority；Database corresponding to the process of equal priority
Access request, the priority for reading the database access request of type are higher than the database access request for writing type；
The database access request in pending data storehouse access request queue is handled successively.
In the present embodiment, the type of mobile terminal can be configured according to being actually needed, for example, mobile terminal can be hand
