Description
Technical Field
The invention relates to the technical field of databases, in particular to a method and a device for updating data of an inventory system.
Background
In order to increase the speed of processing regional data and improve user experience, a distributed inventory system is usually adopted, that is, a partitioned inventory database is established in a region where users are concentrated, the partitioned inventory databases are connected, and the partitioned inventory databases are used for storing and processing inventory data, so that local users can conveniently and quickly access the local databases. In the partitioned inventory database, the inventory data structure exists in the form of a table, called an inventory table, and for the convenience of synchronization, the partitioned inventory database shares the inventory table, and the inventory data in the inventory table exists in the form of fields including an input field for representing an inventory input value, a deduction field for representing an inventory deduction value, and an inventory balance field, wherein the inventory input means that an inventory provider inputs a new inventory value, which is equivalent to inventory input, and the inventory deduction means that an inventory consumer deducts inventory, which is equivalent to inventory output.
When the inventory system is in inventory input or reduction, the inventory data of each partition inventory database needs to be updated synchronously, specifically, when a transaction occurs in a certain place, an input field (when the inventory input occurs) or a reduction field (when the inventory reduction occurs) in the inventory table of the partition inventory database is modified, and the modification can synchronize the same field of the inventory tables of other partition inventory databases. However, transactions in various regions often occur simultaneously, and the same field of the inventory table in each partitioned inventory database changes concurrently, and this concurrency may result in data synchronization conflict, which may cause data errors in the inventory table, and affect real inventory data and transaction processing.
In order to avoid data synchronization conflicts, a single-point modification method is usually adopted, that is, only one inventory database is used to modify the inventory table, and then the modified inventory table is synchronized to each partition inventory database. However, in this way, the transaction information of each region needs to be sent to the inventory database for modifying the inventory table across regions and in a long distance, and then the inventory database for modifying the inventory table modifies the inventory table according to the priority sequence or the time sequence.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but it will be appreciated by those skilled in the art that the present application may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the embodiments.
Fig. 1 is a schematic flowchart of an inventory system data updating method according to an exemplary embodiment of the present application, where as shown in fig. 1, the method includes:
step S101, an area input field and an area deduction field corresponding to the partitioned inventory database are set in an inventory table, the area input field is used for recording inventory increase values in the partitioned inventory database, and the area deduction field is used for recording inventory deduction values in the partitioned inventory database.
The correspondence with the partitioned inventory database may be correspondence with a library identifier of the partitioned inventory database or correspondence with an area identifier of the partitioned inventory database, and accordingly, in the inventory table, the number of the area input fields and the number of the area deduction fields are respectively the same as the number of the partitioned inventory database. For example, the inventory table is provided with region input fields a1, a2, a3 … … an and region deduction fields b1, b2, b3 … … bn corresponding to the partitioned inventory databases W1, W2, W3 … … Wn. The same table structure is used for each partitioned inventory database, namely the inventory tables of the partitioned inventory databases are the same and can be updated synchronously in a linkage mode.
Step S102, when the inventory of the partitioned inventory database is increased, updating the area input field corresponding to the partitioned inventory database, and synchronizing the inventory tables of the partitioned inventory databases;
step S103, when the inventory deduction occurs in the partitioned inventory database, judging whether the inventory balance is greater than or equal to the value of the inventory deduction in the current time;
and step S104, when the inventory balance is greater than or equal to the secondary inventory deduction value, updating the area deduction field corresponding to the subarea inventory database, and synchronizing the inventory tables of the subarea inventory databases.
In an application environment, when the inventory of the partitioned inventory database is increased or decreased, a user modifies a corresponding area input field or an area decrease field to update the area input field or the area decrease field; in another application environment, after the area of the partitioned inventory database is transacted, the area input field or the area deduction field is automatically updated according to the transaction information, for example, the area deduction field is updated according to the sale amount if the transaction is sale and the inventory deduction, and the area input field is updated according to the purchase amount if the transaction is purchase and the inventory is increased.
When the inventory of the partitioned inventory database is increased, updating the area input field corresponding to the partitioned inventory database, namely adding the inventory increase value to the original value of the area input field, wherein the inventory table in the partitioned inventory database is changed, and synchronizing the inventory table of each partitioned inventory database according to the change, so that the area input field corresponding to the partitioned inventory database with the inventory increase in each partitioned inventory database is changed in the same way, and the synchronous updating is completed.
When the inventory deduction of the partitioned inventory database occurs, updating the region deduction field corresponding to the partitioned inventory database, namely subtracting the value of the inventory increase from the original value of the region input field. However, if the inventory balance is insufficient, the inventory deduction cannot be completed. Therefore, when inventory deduction occurs to the partitioned inventory databases, it is first determined whether the inventory balance is greater than or equal to the value of the secondary inventory deduction, where the inventory balance M is ═ Σ (a1+ a2+ … … + an) - ∑ (b1+ b2+ … … + bn), where a1 to an are the region input fields of the partitioned inventory databases, b1 to bn are the region deduction fields of the partitioned inventory databases, and n is the number of the partitioned inventory databases. If the inventory balance is larger than or equal to the current inventory deduction value, inventory deduction can be carried out, the area deduction field corresponding to the partitioned inventory database is updated, the inventory table in the partitioned inventory database changes at the moment, the inventory table of each partitioned inventory database is synchronized according to the change, therefore, the area deduction field corresponding to the partitioned inventory database with the inventory deduction in the inventory table of each partitioned inventory database is changed in the same way, and synchronous updating is completed. If the inventory balance is less than the value of the current inventory deduction, the inventory deduction cannot be carried out, namely the area deduction field corresponding to the partitioned inventory database is not updated, and in this case, an inventory shortage message can be displayed to remind a user that the inventory is insufficient at the moment and the inventory deduction cannot be finished.
Preferably, when the inventory of the partitioned inventory database is changed (increased or decreased), after the area input field or the area deduction field corresponding to the partitioned inventory database is updated, a circular synchronization mode is used for synchronizing the inventory tables of the partitioned inventory databases, because the circular synchronization is used for processing the synchronization of the inventory tables in the multi-master database when the partitioned inventory databases are used as the multi-master database during the synchronization in the present application, and compared with a general method for dividing the multiple databases into master slave synchronization, the method has higher performance and reliability.
It should be noted that there is no precedence relationship between the occurrence of the inventory input and the occurrence of the inventory deduction, so that the steps S102 and S103 (and S104) in the technical solution provided by the present application are not limited by the writing order, that is, step S102 may be executed first, step S103 and step S104 may be executed later, step S103 and step S104 may be executed first, step S102 may be executed later, or step S102 and step S103 may be executed simultaneously.
Fig. 2 is a schematic flow chart of another inventory system data updating method according to an exemplary embodiment of the present application, the method is based on the method shown in fig. 1, and as shown in fig. 2, the method includes:
step S201, setting an area input field and an area deduction field corresponding to the partitioned inventory database in an inventory table, and setting an inventory balance field in the inventory table, where the area input field is used to record an inventory increase value in the partitioned inventory database, the area deduction field is used to record an inventory deduction value in the partitioned inventory database, the inventory balance field is used to record the inventory balance, and the inventory balance M ═ Σ (a1+ a2+ … … + an) - ∑ (b1+ b2+ … … + bn), where a1 to an are area input fields of the partitioned inventory databases, b1 to bn are area deduction fields of the partitioned inventory databases, and n is the number of the partitioned inventory databases;
step S202, when the inventory of the partitioned inventory database is increased, and when the inventory of the partitioned inventory database is increased, updating an area input field corresponding to the partitioned inventory database, updating the inventory balance field, and synchronizing inventory tables of the partitioned inventory databases;
step S203, when the inventory deduction occurs in the partitioned inventory database, judging whether the inventory balance field is larger than or equal to the numerical value of the current inventory deduction;
and step S204, when the inventory balance is greater than or equal to the secondary inventory deduction value, updating the area deduction field corresponding to the partitioned inventory database, updating the inventory balance field at the same time, and synchronizing the inventory tables of the partitioned inventory databases.
And step S205, when the inventory balance is less than the value subtracted by the secondary inventory deduction, displaying an inventory shortage message.
When the inventory deduction of the partitioned inventory database occurs, in the above embodiment, when it is determined whether the inventory balance is greater than or equal to the value of the secondary inventory deduction, the inventory balance value is calculated, and when the inventory of the partitioned inventory database increases, the inventory balance value is not calculated and the inventory balance is not updated, which may cause an error in calculating the inventory balance value under the condition of inventory deduction due to a blank update of the inventory balance under the condition of inventory increase, so that the obtained inventory balance value has an error from the actual inventory balance value, and if the inventory balance value is calculated incorrectly, the system may be crashed due to the incorrect inventory deduction.
As in the embodiment shown in the figures, in this embodiment, the sequence between step S202 and step S203 (and step S204) is not limited by the writing sequence, that is, step S202 may be executed first, step S203 and step S204 may be executed later, step S203 and step S204 may be executed first, step S202 may be executed later, or step S202 and step S203 may be executed simultaneously.
Therefore, in this embodiment, in addition to the area input field and the area deduction field, an inventory balance field for recording the inventory balance is set in the inventory table. When the inventory of the partitioned inventory database is increased, updating an area input field corresponding to the partitioned inventory database, and updating the inventory balance field at the same time, namely calculating the inventory balance after the inventory is increased, and updating the inventory balance field to a calculation result; and when the inventory deduction occurs to the partitioned inventory database, updating the area deduction field corresponding to the partitioned inventory database, and updating the inventory balance field at the same time, namely calculating a new inventory balance value after the inventory deduction, and updating the inventory balance field to a calculation result. Thus, because the inventory balance field is updated in real time, when the inventory deduction occurs, the inventory balance field can be directly read without calculating the inventory balance, and whether the inventory balance field is larger than or equal to the current deduction value is judged.
According to the technical scheme provided by the embodiment of the application, the area input field and the area deduction field corresponding to the partition inventory database are set in the inventory table, when the inventory of the partition inventory database is increased or reduced, only the area input field or the area deduction field corresponding to the partition inventory database needs to be updated, therefore, even if inventory of a plurality of partition inventory databases is changed at the same time, only the area input field or the area deduction field corresponding to each partition inventory database needs to be updated respectively, the situation that the same field is updated at the same time is avoided, and data synchronization conflict can be well avoided. When the inventory of each partition inventory database is changed, the corresponding area input field or the corresponding area deduction field can be updated locally in the partition inventory database, and then the inventory table is synchronized, and other partition inventory databases do not need to be remotely accessed to update and modify, so that the data updating response time is short, and the improvement of the throughput, the availability and the user experience of the system is facilitated.
Through the above description of the method embodiments, those skilled in the art can clearly understand that the present application can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation manner in many cases.
