 [0003] Existing types of physical cards, such as membership cards, bank cards, and loyalty cards, need to have a unique card number identifier. If a duplicate card number occurs, the management data of the background system may be wrong, for example, the consumption credit information of the two membership cards is recorded in the same data record. Therefore, before creating and distributing each physical card, it is necessary to pre-generate a physical card number for uniquely identifying the physical card.

 [0004] In the prior art, a corresponding type of physical card number is generated for a certain type of service, which is usually generated in a server of a business management system, based on functions provided by various bursting languages such as Java and Javascript. Random number. After each random number is generated, it is necessary to determine whether the random value is a physical card number already existing in the service management system. If the random value is not a physical card number already existing in the service management system, the random value may be recorded to use the random value as a new physical card number for making a new physical card. However, if a large number of physical card numbers already exist in the physical card number record table of the service management system, it is often necessary to repeatedly perform the above functions multiple times in order to obtain a random value that does not exist in the physical card number record table, thereby causing The generation efficiency of the physical card number is relatively low; and the generated physical card number can only be guaranteed not to be repeated in the server of the same service management system. If the service management system has multiple distributed servers, duplicate physical card numbers will still be generated, resulting in confusion of business data.

 Beneficial effect

 [0024] In the embodiment of the present application, the service system only needs to send a sequence value call request to the first server based on the second server, so that the current sequence value of the sequence object created by the first server and the random code generated by the first server can be performed.

Embodiments of the invention

 [0034] In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the application.

 [0035] In order to explain the technical solutions described in the present application, the following description will be made by way of specific embodiments.

 [0036] FIG. 1 is a system architecture diagram of a method for generating a physical card number provided by an embodiment of the present application. For convenience of description, only parts related to the embodiment are shown.

[0037] Referring to FIG. 1, the system is composed of a first server 11 and a plurality of second servers 12. The first server 11 is configured to distribute the current sequence value after each update of the sequence object according to the sequence object created in advance, so that each sequence value corresponding to the sequence object can be spliced with a random code as a The physical card number used to make the physical card. Specifically, the above sequence object exists in the database of the first server 11. The foregoing database is further configured to store the service data related to the second server 12, so that the first server 11 can manage the service data and distribute the business data of the same number of the physical card number for the second server 12. No additional setup of the database is required.

 In the system, the second server 12 is configured to, as a requesting client, send a sequence value call request to the first server 11 to enable the first server 11 to update the current sequence value of the sequence object according to the request. The second server 12 is also used to run a business system of one or more types of services, so that each response returned by the first server can be output as a physical card number required by the business system.

 [0039] FIG. 2 is a flowchart showing an implementation of a method for generating a physical card number according to an embodiment of the present application, which is described in detail as follows:

[0040] S201: Create a sequence object in a database pre-established by the first server.

 [0041] The database pre-established by the first server includes but is not limited to Omcle, Sql

 Server. DB2 and PostgreSQL and other types of databases. Because the Oracle database is portable, easy to use, and powerful, it is applicable to all kinds of large, medium, small, and micro-computer environments. Therefore, the database established in the embodiment of the present application is preferably an Oracle database.

 [0042] In the Oracle database, when a sequence creation instruction issued by an external system or a database administrator is received, a sequence object is created by a preset sequence generation method. A sequence object is a database object that is used to generate a series of unique values, which is a special one-line table.

 [0043] As an embodiment of the present application, FIG. 3 shows a specific implementation process of the physical card number generation method S201 provided by the embodiment of the present application, which is described in detail as follows:

 [0044] S2011: Acquire an attribute parameter input by the user related to the sequence object, where the attribute parameter includes a minimum sequence value, a maximum sequence value, a step size, an initial value, and a loop option value.

 [0045] In the Oracle database, an instruction is created according to a sequence input by the user, such as create

 The sequence and the create any sequence statement, etc., create an Oracle sequence object. The sequence creation instruction carries the attribute parameters related to the sequence object that the user needs to create, including the minimum sequence value, the maximum sequence value, the step size, the initial value, and the loop option value.

[0046] The sequence creation instruction carrying the attribute parameter related to the sequence object that the user needs to create may be defined as follows:

[0047] CREATE SEQUENCE sequence

[0048] INCREMENT BY n

 [0049] START WITH a

[0050] MAXVALUE b [0051] MINVALUE c

 CYCLE I NOCYCLE

 [0053] wherein the above sequence, n, a, b, c, and CYCLE / NOCYCLE are all attribute parameters of the sequence object. Sequence represents the sequence name of the sequence object; n represents the step size of the sequence object; a represents the initial value of the sequence value; b and c represent the maximum and minimum values of the sequence object, respectively; CYCLE

 And NOCYCLE is the loop option value of the sequence object, and CYCLE indicates that the sequence object can be looped, and N OCYCLE indicates that the sequence object cannot be looped. The step size indicates the difference between the next sequence value and the current sequence value in the sequence object.

 [0054] S2012: In a database pre-established by the first server, a sequence object is created based on the attribute parameter, and the initial value is output as a current sequence value of the sequence object.

 [0055] According to the received sequence creation instruction, each attribute parameter in the sequence creation instruction is parsed to create a sequence object matching the attribute parameter in the database.

 [0056] Preferably, the attribute parameter further includes a memory option value. If the memory option value is CACHE, the sequence object is stored in memory to improve the processing speed of the sequence value and improve the efficiency of each sequence value in the sequence object.

 [0057] In the embodiment of the present application, each sequence value corresponding to the sequence object is finally output together with the random code as a physical card number required by the service system, so that the attribute parameter of the sequence object input by the user can be provided to the user. More custom space allows the user to customize the generation rules of a part of the physical card number according to the card-making requirements of the business system, thus improving the flexibility of the distribution of the physical card number to a certain extent.

 [0058] S202: When receiving the sequence value invoking request issued by the second server, acquiring the sequence object that has been created, and reading the current sequence value of the sequence object.

 [0059] In the second server, one or more management systems are run, each management system for managing business data associated with one type of service.

[0060] When any business system needs to acquire a new physical card number, a sequence value invocation request based on the sequence object that has been created in the Oracle database is generated, and the sequence value invocation request is sent to the above Oracle database. When the Oracle database receives the sequence value call request issued by the second server, the operation instruction matching the sequence value call request is executed, that is, the sequence name carried by the request is called according to the sequence value, and the sequence object matching the sequence name is obtained. , and read the current sequence value of the sequence object. Due to different sequences The sequence name carried by the value invocation request corresponds to one type of service, so different types of services will call different sequence objects, so that duplicate card numbers will not appear under the same type of service.

[0061] In the embodiment of the present application, the current sequence value of the sequence object is obtained by the pseudo column currval mode.

[0062] S203: Generate a next sequence value of the sequence object according to a preset step size and the current sequence value.

And updating the current sequence value of the sequence object to the next sequence value.

[0063] According to the preset step size corresponding to the sequence object and the current sequence value obtained by S202, the next sequence value of the sequence object is generated by the pseudo column next val, and the current sequence value of the sequence object is replaced. Is the next sequence value.

 [0064] For example, after receiving the sequence value call request issued by the second server, if the current sequence value of the sequence object that is read to match the sequence value call request is a, and the growth step of the sequence object is 2, The next sequence value generated is a+2, and at the latest engraving, the current sequence value of the sequence object will be changed to a+2.

 [0065] S204: Acquire a card number length value carried by the sequence value invoking request and obtain a character length of the updated current sequence value.

 S205: Obtain, according to a difference between the card number length value and a character length of the current sequence value, each character length of the difference is obtained.

 [0067] When receiving the sequence value call request sent by the second server, the sequence value call request is parsed to obtain the card number length value and the sequence name carried by the sequence value call request. The card number length value indicates the character length of a physical card number that the second server needs to obtain; the sequence name indicates the name of the sequence object to be called by the second server.

And [0068] calling the sequence name carried by the request according to the sequence value, causing the sequence object matching the sequence name to generate the next sequence value, and updating the next sequence value to the current sequence value, and identifying the character length of the current sequence value. . Calculates the difference between the card number length value carried by the sequence value call request and the character length of the current sequence value.

 For example, if the card number length value is 11 bits and the current sequence value is 238246223, the current sequence value has a character length of 9 bits, and the difference between the card number length value and the current sequence value character length is 11-9=2.

[0070] All values having the same number of bits as the above difference are obtained. For example, in the above example, if the difference between the card number length value and the character length of the current sequence value is 2, the value to be acquired is a value of 2 digits, that is, all values between 00 and 99. [0071] S206: Obtain one or more of the values with the highest probability of selection according to a selection probability preset by each of the values, and determine one of the values as a random number generated by the current engraving code

[0072] Values of different numbers of bits are generated in advance on the first server. Wherein, each value having the same number of bits is stored in advance in a data table, and each value corresponds to a selection probability. The probability of selection of each value is used to represent the probability that the value can be selected as a random code for all values of the same number of bits. In the initial state, the selection probability of each value in the same data table is the same, both are 1/10, which is the number of digits.

[0073] For example, in generating a hundred values 00 between 00 and 99, for each of these values, the probability of selection in the initial state is 1/100.

[0074] Among the respective values obtained by S205, one or more values having the highest selection probability are determined. Through the preset random number selection algorithm, a value is selected among the determined values, and the value is used as the random code generated by the current engraving. It can be seen that the character length of the random code is the difference between the card number length value and the character length of the current sequence value.

 [0075] S207: splicing the random code with the updated current sequence value, and returning the splicing result to the second server, so that the second server outputs the splicing result as a physical card number. .

 [0076] Before returning the physical card number, the first server places the generated random code before the current sequence value of the sequence object, and concatenates the random code and the current sequence value by a preset splicing algorithm, thereby outputting an actual card number. It can be seen that the length of the card number of the output physical card number is the same as the length of the card number carried by the sequence value call request.

 [0077] The embodiment of the present application is applicable to a case where the physical card number generated by the service system is different from the character length of the current sequence value of the sequence object, for example, if the service system needs to allocate an entity card number of 11 digits in length, If the current sequence value of the sequence object in the database is 9 bits, the difference between the card number length value carried by the sequence value calling request and the updated character length of the current sequence value is 2, so a random code of 2 digit values is generated, so that 2 The random code of the bit value and the current sequence value of the 9-digit number can be output as an 11-bit physical card number required by the business system after splicing to meet the actual needs of the service.

[0078] In the embodiment of the present application, the service system only needs to issue a sequence value call request to the first server according to the second server, so that the current sequence value of the sequence object created by the first server and the random number generated by the first server can be generated. The code is stitched to output as a new physical card number. Since the current sequence value of the sequence object is updated after the actual generation, there is no repeated distribution of the same entity card number, thereby enabling the service system to directly obtain the current sequence value of the sequence object each time it is obtained. The result of the splicing with a random code is output as the physical card number, and it is not necessary to judge whether the physical card number already exists, thereby improving the generation efficiency of the physical card number. By parsing the sequence value to call the card number length value carried in the request, the random code of different character lengths can be dynamically obtained according to the difference between the card number length value and the current sequence value; and the first server is spliced by splicing the random code with the current sequence value The output physical card number can match the actual card number length value required by the service system, thereby satisfying the actual needs of different service systems; since the random code has different lengths and its value is random, it is compared with the current sequence value. The splicing further reduces the repetition probability of the physical card number. In addition, multiple service systems can share sequence objects in the database of the first server, so that a unique physical card number is generated across the service system and across servers, thereby avoiding the problem of duplicate physical card numbers between multiple distributed servers. .

 [0079] As another embodiment of the present application, as shown in FIG. 4, after the foregoing S202, the method further includes:

 [0080] S208: If the current sequence value of the sequence object is the same as the maximum sequence value, and the loop option value is not looping, stop generating the next sequence value of the sequence object.

 [0081] S209: Let the database issue a sequence value exhaustion prompt, and return a rejection response after receiving the sequence value call request issued by the second server.

 [0082] The maximum sequence value is the maximum value among the respective sequence values corresponding to the sequence object defined by the user. If the current sequence value read in step S202 is the same as the preset maximum sequence value, the loop option value of the sequence object is read to determine whether the loop option value is a loop or not.

[0083] If the loop option value is not looped, the database issues a sequence value exhaustion prompt to prompt the database administrator that each sequence value corresponding to the sequence object currently created has been assigned to the matching business system, ie, prompt There are no other sequence values available for allocation in the database manager's current sequence object. Therefore, based on the sequence value exhaustion prompt, the database administrator can confirm whether another sequence object that matches the business system needs to be recreated. If another sequence object needs to be recreated, the database administrator can re-enter the attribute parameters of the new sequence object. Before receiving the sequence creation instruction, if the sequence value call request sent by the service system is continuously received, the rejection response information is returned to the second server where the service system is located. [0084] Preferably, in the default state, the loop option value of the sequence object is not looped.

 [0085] In the embodiment of the present application, by reaching the maximum sequence value in the current value of the sequence object, and the loop option value is not looping, the sequence value exhaustion prompt is issued, so that the database administrator can know the actual allocation state of the sequence value. And 吋 establish a new sequence object to ensure that each business system can normally obtain the sequence values in the database, and improve the operational stability of the entire physical card number distribution system. Since the loop option value is not looped, the assigned sequence values are not cyclically acquired, so the same sequence value is not repeatedly distributed to other service systems. Therefore, the entity card number generation method provided by the embodiment of the present application implements the cross Business systems and the generation of unique physical card numbers across servers avoid the problem of duplicate physical card numbers between multiple distributed servers.

 [0086] As an embodiment of the present application, FIG. 5 shows an implementation flow of a method for generating a physical card number according to another embodiment of the present application, which is described in detail as follows:

 [0087] S210: Obtain a history data table, where the history data table is used to record a historical random code generated by each engraving.

 [0088] S211: Determine, according to each historical random code stored in the history data table, the number of occurrences of the random code generated by the current engraving in the historical record data table.

In the embodiment of the present application, after determining a value used as a random code from each of the pre-generated values, the random code is stored in the history data table to become a historical random code.

[0090] After selecting a random code currently engraved in S206, it is determined whether the random code is the same as any historical random code in the history data table.

[0091] if the random code is the same as any of the historical random codes in the history data table, determining the number of the same historical random code as the random code, that is, determining the random code in the historical data table The number of occurrences

. It can be seen that the number of occurrences represents the number of times the random code has been used.

[0092] S212: For each character bit of the random code, determine a cumulative number of times that the value of the historical random code on the character bit is the same as the value of the random code on the character bit.

[0093] For the random code generated by the current engraving, the value on each character bit thereof is read. For example, if the random code is "132", the values in the ones, tens, and hundreds are "2", "3", and "1", respectively.

[0094] For the value of the random code on each character bit, the number of times the value appears on the same character bit of the historical random code is separately counted. The cumulative number represents the sum of the number of times corresponding to each character bit. among them After counting the cumulative number of times, the number of characters in the historical random code is the same as the number of characters in the random code generated by the current engraving. According to the cumulative number of times obtained by the statistics, the number of times the random code is generated on each character bit can be known.

 [0095] S213: input the character length x of the random code, the number of occurrences y, and the cumulative number of times z into a preset formula to obtain an output parameter P.

[0096] wherein the preset formula is as follows:

P=(l-y/z)/10 " , y≠0^.z≠0;

Ρ=(1+ζ/10 /10 , y≠0^.z≠0;

[0099] P = 1/10 ^x , y = 0 and z = 0.

 [0100] S214: Adjust the selection probability of the random code to the output parameter P.

 [0101] If the number of occurrences y of the random code generated by the current engraving is not zero, and the cumulative number z of occurrences of the same value on the character bit is not zero, it indicates that the number of times the random code is used to create the physical card number is relatively There are many, so in the data table in which S205 stores the value and its selection probability, the selection probability of the value corresponding to the current random code is lowered, and the selection probability is changed to (ly/z)/10 x.

[0102] If the number of occurrences y of the random code generated by the current engraving is zero, but the cumulative number z of occurrences of the same value on the character bit is not zero, it indicates that the random code has never been used to create a physical card number, and thus S205 stores a numerical value and a probability of selecting the data table, and increases the selection probability of the value corresponding to the current random code to adjust the selection probability to (l+z/10 /10).

[0103] If the number of occurrences y of the random code generated by the current engraving is zero, and the cumulative number of occurrences of the same value on the character bit is also zero, the selection probability of the value corresponding to the random code is changed to the initial state. The probability of selection is 1/10.

 [0104] In the embodiment of the present application, after each random code is generated, by increasing the random code selection probability in the case where the random code and the number of occurrences of the character bit are high, the value of the random code and its character bit When the number of occurrences is low, the selection probability of the random code is lowered, and the automatic adjustment of the selection probability of the random code is realized, so that the first server generates the random code 下次 based on the selection probability in the data table next time, which can avoid the maximum This engraving generates a random random code. The splicing of the sequence values based on the less repetitive random code further reduces the repetition probability of the physical card number obtained after splicing.

[0105] As an embodiment of the present application, FIG. 6 shows a method for generating a physical card number provided by an embodiment of the present application. The specific implementation process of 207 is detailed as follows:

 [0106] S2071: Invoking a service identifier carried in the request according to the sequence value, and searching for a service code corresponding to the service identifier in a preset data table.

 [0107] In the sequence value invoking request, in addition to carrying the card number length value and the sequence name, the service identifier corresponding to the service system that issues the sequence value invoking request is carried. Each type of service has a unique business identity. Before the sequence object is created, in the database of the first server, according to the setting instruction issued by the database administrator, a data table is pre-established for storing the correspondence between the service identifier and the service code.

 [0108] After parsing the service identifier carried in the sequence value call request, the service code corresponding to the service identifier is matched from the data table. For example, if the service is represented as "KTV-VIP", the corresponding service code is "124"; if the service is represented as "KTV-NORMAL", the corresponding service code is "123".

 [0109] S2072: splicing the service code, the random code, and the updated current sequence value in sequence, and returning the splicing result to the second server, so that the second server will perform the splicing result The output is the physical card number.

 In the embodiment of the present application, the currently obtained service code, the random code generated in the above step S206, and the current sequence value after the sequence object update are sequentially spliced, and the physical card number in another combination manner is used. Thereafter, the physical card number returned to the second server is composed of three pieces of information, which are a service code, a random code, and a current sequence value.

 [0111] Exemplarily, if the service code is "103", the random code is "382", and the current sequence value is "233999903", the splicing result obtained by sequentially splicing the three parts of information is "103382233999903", That is, the physical card number obtained by the second server is "103382233999903".
