Below mainly to solving the methods of the many records of database, be described:
The access interface encapsulation work that service creation environment provides SQL SIB to carry out database, business development personnel only need to fill in SQL SIB needs the database SQL statement of execution or the storing process of database, user can configuration database type, such as being configured to oracle database or sybase database etc.Preferably, can also configure the separator of setting in return data, and configure whether return to many records, and return to some configuring conditions such as which bar record.The SQL statement of these configuring conditions and execution is written in the business datum file that this SQL SIB is corresponding.
Service creation environment is compiled into scale-of-two business datum file by the business editting, by intelligent network management module, the business datum file setting is loaded into service control node (Service Control Point, referred to as SCP) upper, by business logic processing module, be responsible for resolving and carrying out the intelligent network business loading.The address of service of configuration database, port numbers and database-name on SCP, database access module reads these configuration informations.
When intelligent network triggers calling, IN business, wherein, IN business refers in certain specific region, and calling is not paid.In the process that business is processed, when processing SQL SIB, business logic processing module is encapsulated into SQL SIB configuration information in message header, the information of main encapsulation include but not limited to following one of at least: type of database, database-name, whether return to many records, return to the information such as which bar record, data delimiter, timer time and the sequence of operation number, and SQL statement or database store process are encapsulated in message body, according to the database address of SCP configuration and port numbers, send socket message to target database access modules.
Target database access modules is resolved message according to predetermined message format, from the message of resolving, separates message body, carries out SQL statement or storing process in message body.Database access module returns to the data set of operating result according to the configuration information in message header.Database manipulation result set mainly can be divided into two kinds of situations: unirecord situation and many record cases.
For returning to unirecord situation, can be divided into again two kinds of scenes: 1) in result, only have a record, 2) there are many records in result, only return to a certain record wherein.
For the 2nd kind of above-mentioned situation, can according to message header configuration, return to the numbering of which bar record by database access module by the mode of circulation, take out this record.Data set result is encapsulated in message body, Information encapsulations such as result signs (success or failure), data amount check (data amount check that refers to wall scroll record the inside here), the sequence of operation number in message header, this socket message is sent to message source, and message source herein can be business logic processing module.
Business logic processing module is resolved this message according to predetermined return messages form, parses the sequence of operation number in message header, and judges whether it is the results messages of oneself asking according to this sequence of operation number.If the sequence of operation number of request is consistent with the sequence of operation of returning number, receive so the result set of this message, and according to the separator configuring, one by one by Data Analysis out.If the sequence of operation number of request and the sequence of operation of returning are number inconsistent, abandon so this message, continue the message of waiting for that database returns.
For returning to situations about recording: be divided into again two kinds of scenes: 1) once return to many records more; 2) repeatedly return to unirecord.
For the situation of above-mentioned many records, whether repeatedly return, can be configured according to the SQL SIB of business.Above-mentioned scene 1) request, some special processing that database access module need to be done, for example: indicate the data amount check of wall scroll record, and all records are put in message body successively, with separator, separate.Such as there being 3 records (A, B, C), separator is ", ", and every records 5 data, and message body can be according to following data layout store data:
“A1,A2,A3,A4,A5,B1,B2,B3,B4,B5,C1,C2,C3,C4,C5”。
Database access module sends to message source by the socket message assembling.
Business logic processing module more record return messages form message is resolved according to predefined, and different message formats, can distinguish by different message event number.Resolve and mainly comprise the following steps:
S1: the data amount check that parses wall scroll record in message header;
S2: according to separator, once take out the data of wall scroll record data number;
S3: often getting is exactly once a record, until the data of message body are taken.
The record that just all databases can be returned by the way all takes out once, greatly improved the efficiency of accessing database, aforesaid way is especially applicable to the smaller scene of unirecord data, can greatly improve the execution efficiency of intelligent network business, also improve the performance of intelligent network access database.
For above-mentioned scene 2) many records situation about repeatedly returning, in order to make intelligent network business exploitation more succinct, the situation of the message that database access module repeatedly returns many records, can in message header, expand a zone bit, this zone bit is used to indicate whether the last item record of current Visitor Logs.Business logic processing module parses goes out after this sign, if not the last item record, continues to wait for that database returns to other data recording, till to the last a record returns.
Preferably, when intelligent network business request access database manipulation, in order to prevent that intelligent network from waiting as long for, can increase timer mechanism, user can directly fill in time-out time, from business logic processing module sends request, record the current time, if do not receive replying of database access module in official hour, no longer wait for, the error handling processing of directly dishing out, thus prevented because database chain rupture causes the generation of the problem that a large amount of intelligent network business blocks.
For above-mentioned whole intelligent network access database flow process, can as shown in Figure 7, comprise following step:
Step S702: user uses service creation environment compiling SQL SIB, the SQL statement or the storing process that need execution is set, and configures the information such as timer, data delimiter; Service creation environment compiling generates service scripts, and by service management module loading to intelligent network platform.
Step S704: the configuration informations such as address, port numbers and database-name of user's configuration database in SCP, database access module carries out according to these configuration informations and database server alternately.
Step S706: when intelligent network business is carried out SQL SIB, business logic processing module by SQL statement and data configuration Information encapsulation in message, and this message is sent to database access module, by database access module, send to the complete corresponding database manipulation of database server.
Step S708: database access module returns to business logic processing module by the database manipulation result data collection receiving, thereby completes the request of access of IN DataBase, and database access result data collection is delivered in intelligent network business and carried out.
