detailed description

The embodiments of the present invention disclose a method and a system for performing service control based on service componentized application software. To better clarify the objects, technical solutions, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. .

FIG. 1 is a schematic diagram of a method according to an embodiment of the present invention, including:

5101. Acquire a data buffer according to the service connection request sent by the channel, where the service connection request carries a service function identifier.

The channel refers to an external system associated with the current application software on the business function, and is used to initiate a service connection request to the application software. Taking the core business system of the bank as an example, the channel for launching the function of the personal deposit business may be the operator who refuses to face the bank front desk, or the bank ATM machine, or the online banking system.

The structure of the data buffer can be seen in Figure 2. The data buffer includes a sub-buffer, a buffer meta-array, and a data element linked list. The sub-buffer includes a sub-buffer name, a number of buffer elements included in the sub-buffer, and a position indication of each buffer element in the buffer element array. The buffer element array records indication information of the access addresses of the respective data element linked lists; the data element linked list records the first service data and the second service data.

The general sub-buffer name is the same as the service function identifier stored in the sub-buffer, and is used to indicate the service function recorded in the sub-buffer. The function of the service function identifier is used to distinguish different service functions, which can be the service function number or the service function name. In Figure 2, the business function numbers are used to identify different business functions.

In Figure 2, the personal account withdrawal service in the financial industry is numbered 1131 as an example to illustrate the various parts of the data buffer area. The name of sub-buffer 1 is 1131, which indicates that the sub-buffer records the business function with service function number 1131. The number of buffer elements is 2, indicating that the service function corresponds to two buffer elements in the buffer element array of the buffer, and 1 and 10 indicate that the first access address of the two buffer elements is located by The first bit of the buffer meta array is pointed to, and the other access address is pointed to by the 10th bit in the buffer meta array.

S102: Obtain an action sequence table corresponding to the service function according to the service function identifier. Different service function identifiers correspond to different business functions, and each business function has a corresponding action sequence table. The action sequence table is pre-stored in the local system and can be found in the local system through the service function identifier.

The action sequence table contains the action steps performed by a business function at runtime and the program interface corresponding to each step. Therefore, according to the action sequence table, external data and internal data required to complete the current service function can be obtained.

Taking the personal account withdrawal service with service function number 1131 as an example, the action steps specified in the action sequence table corresponding to the service function include: calling 1131 to read the data packet, calling 1131 to read the database, calling the 1131 business program, and calling 1131 to write the data packet. , call 1131 to write the database.

5103. Acquire first service data from a channel according to the action sequence table, and obtain second service data from a database.

The first service data and the second service data are respectively used to identify data related to the implementation of the current business function obtained from the channel and the database.

For example, the personal account withdrawal service with service function number 1131 is taken as an example. At this time, by executing the call 1131 to read the data packet in the action sequence table, the step obtains the first service data from the channel, including the account number, password, amount, and the like. The second service data is obtained from the local database by executing the "call 1131 read database" step in the action sequence table, including account number, account name, account balance, currency, password, etc. In the action sequence table, different business functions The steps corresponding to the identification involve different business data.

S104: The first service data and the second service data are stored in the data buffer.

5105. Each service component corresponding to the service function performs related service functions by using the first service data and the second service data stored in the data buffer.

5106. The first service data and the second service data whose contents in the buffer are changed are fed back to the channel according to the action sequence table, and are written into the database.

After the service component related to the service function performs the related operation by using the first service data and the second service data in the data cache area, the first service data or the second service data may be changed, so the buffer needs to be The first service data and the second service data whose contents change in the area are fed back to the channel and written into the database, so as to ensure the consistency of the channel data and the synchronization of the database data.

For example, the personal account withdrawal service with service function number 1131 is taken as an example. In order to withdraw 1000 yuan from the personal account, the account balance of the account will change. At this time, the "call 1131 write data packet" step in the action sequence table is executed, and the changed account balance information is fed back to the channel; In the "call 1131 write database" step, the account balance information is written into the database according to the account number.

Optionally, the method provided by the embodiment of the present invention further includes:

S107. Release the data buffer for use by other business functions.

According to the method provided by the embodiment of the present invention, the action sequence table is obtained according to the service function identifier, and the service data required to execute the service function is stored in the acquired data buffer according to the action sequence table, and the service function corresponds to The business component directly operates the data in the data buffer when performing the business function. At the same time, after the business function is executed, the changed business data is written into the database or fed back to the channel, thereby fundamentally avoiding each The direct access of the business components to the database solves the problem of database overload and even deadlock.

In addition, the method provided by the embodiment of the present invention stores the required service data in the data buffer before the execution of the service function, and writes the changed service data into the database or returns to the channel after the execution of the service function. Each service component related to the function directly operates on the data buffer, thereby avoiding frequent interaction processes between various service components and the database, thereby further improving the efficiency of business processing.

In order to make the method provided by the embodiment of the present invention more clear, the following provides a description of the method provided by the implementation of the present invention by taking the personal account withdrawal service (service function number 1131) in the financial industry as an example.

FIG. 3 is a schematic diagram of a scenario applied by an embodiment of the present invention, where the service support system 301 is an execution entity of a method provided by an embodiment of the present invention, and the service function 302 is a service function entity of a current application software, where multiple Business component. Database 303 is an internal data storage management system used by current application software. The channel 304 is an external system in which the current application software is associated with the service function. In the personal account withdrawal service provided by the embodiment of the present invention, the channel may be an ATM automatic teller machine.

Optionally, in order to separate the specific service function from the interface, the channel, the database, and the service function program respectively provide access interfaces, respectively, channel interface 304-I/O, database interface 303-I/O And business function program interface 302-I/O, these three interfaces are conceptually consistent with the application programming interface (API) in the software engineering field. In this structural mode, the business support system passes Interfaces with these entities enable access and control of entities.

The service support system is always in the listening connection state. When the channel initiates a service function, it initiates a service connection request to the runtime support system through the channel interface, and the runtime supports the system to respond to the connection and start working. Specifically, the method includes obtaining a blank, available data buffer according to the service connection request.

The service support system obtains an action sequence table corresponding to the service function according to the service function number 1131.

After the service support system calls the system level initialization program and completes some basic system initialization functions, it searches according to the service function identifier and finds its corresponding action sequence table.

5403. The “call 1131 read data packet” step in the action support system execution action sequence table obtains the first service data from the channel, and executes “call 1131 to read the database in the action sequence table, and the step obtains the second service data from the local database. .

Specifically, the service support system acquires, according to the action sequence table, the first service data required by the current service function, such as an account number, a password, and an amount, from a channel (such as an ATM); from the database connected to the current service support system. The related second service data required for the current business function, including account balance, currency, password, and the like.

S404: The service support system stores the first service data and the second service data in the data buffer.

It should be noted that, in practical applications, a service function may correspond to multiple sub-buffers, but the structure of each sub-buffer is the same regardless of the number of sub-buffers included in one service function. . S405. The service support system schedules and executes a personal account withdrawal service program, where each service component of the service program performs related business functions by using the first service data and the second service data stored in the data buffer.

5406, the service support system executes the "call 1131 write data packet" step in the action sequence table to feed back the account balance to the channel; and by executing the "call 1131 write database" step in the action sequence table, the account balance information is written according to the account number. database.

After the relevant business functions are executed, the account balance is changed from 16050.00 to 15050.00. The second business data changes, and the business data needs to be written into the database. Since the second service data has changed, in order to keep the data in sync, the changed second service data needs to be fed back to the channel (ATM automatic teller machine) for viewing by the operator or the user.

In practical applications, the service support system determines the changed service data according to the execution result of the specific service function, and feeds back to the channel and/or writes to the database.

5407, the business support system releases the data buffer used by the personal account withdrawal service.

The buffer of the system is limited. In order to improve the buffer utilization, the data buffer used by the service function needs to be released after the execution of a service function, so that other service functions can be used for application.
