Abstract

The invention discloses a component and an implementation method for implementing WEBSERVICE transaction control through a PB12 (power builder 12), which belong to the technical field of computer application. The implementation method is characterized by A, implementing uniform transaction objects, providing registration transaction objects for a client side and having uniform properties and methods; B, implementing uniform database SQL (structured query language) execution objects for executing SQL commands through the transaction objects; C, implementing uniform data window objects and exchanging the data window objects with a database through a data window of the PB by the aid of the client side; and D, implementing uniform registration transaction objects and registering and canceling transactions through the registration transaction objects by the aid of the client side. Compared with the prior art, the component and the implementation method for implementing WEBSERVICE transaction control through the PB12 solve the problem that a developer cannot control transactions through Webservice, improve development inexpensiveness, and have excellent popularization and application values.

Description

Realize the assembly and the implementation method of the control of WEBSERVICE affairs through PB12

Technical field

The present invention relates to Computer Applied Technology, specifically a kind of assembly and implementation method that realizes the control of WEBSERVICE affairs through PB12.

Background technology

In Traditional Web service exploitation system, affairs control requires to submit to the necessary disposable submission of affairs generally through single affairs control, and is more to developer's restriction ratio under this background, causes bad processing code under some situation.Such as, in Webservice, require each client in oneself viewing content within the affairs independently.Difficult realization the in this former exploitation system.

Summary of the invention

Technical assignment of the present invention is the deficiency to above-mentioned prior art, and a kind of assembly and implementation method that realizes the control of WEBSERVICE affairs through PB12 is provided.Utilize this method developer just can registration transactions arrive server end in client, service end is returned affairs ID after the success, and the user is through the affairs of this ID Control Server end.

Technical assignment of the present invention is realized by following mode: the assembly through PB12 realizes the control of WEBSERVICE affairs is characterized in:

A, the unified transaction object of realization provide client registration transactions object, have unified attribute and method;

B, realization unified data storehouse SQL carry out object, and this object is carried out sql command through transaction object;

C, realization unified data window object, client can be mutual with database through the data window of PB with this object;

D, the unified registration transactions object of realization, client is through these object Register Cancel affairs.

Among the A:

Said transaction object connects database;

Transaction object is responsible for rollback and is submitted client transaction to;

Database linkage information is set.

Among the B:

SQL carries out object and carries out SQL through transaction object;

SQL carries out object can obtain database information, carries out the SQL grammer of appointment.

Among the C:

The data window object passes through transaction object alternately with database;

Can form the database grammer according to SQL statement;

According to data window grammer refresh data that imports into and return data window grammer;

Data window grammer according to importing into Updates Information.

The method that realizes the control of WEBSERVICE affairs through PB12 may further comprise the steps:

A, set up the discernible class libraries of Framwork through PB12, client transaction is through this class libraries Register Cancel and operation affairs;

B, in Framwork, quote the class libraries that uses PB12 to create, and be issued as IIS;

C, be the Webservice object encapsulation interface object, all are realized through this object with the Webservice interactive action.

Further, steps A comprises:

A, according to the different objects of difference in functionality module creation, comprise and carry out SQL object, service data window object;

B, the unified transaction object of use;

Unified interface object is used in c, external issue.

Compared with prior art, the developer can realize the affairs control of remote server through method of the present invention in software, and solving the developer can't be through the problem of Webservice control affairs.

The developer disposes assembly of the present invention in development environment, through this assembly claimed alternative, accesses remote databases can reach the purpose of control affairs, has effectively reduced code development quantity, has improved the cheap property of exploitation.

Description of drawings

Accompanying drawing 1 is that the present invention calls schematic diagram through the exploitation of PB12 realization WEBSERVICE affairs Control Component.

Embodiment

Realize assembly and implementation method work below at length explanation that WEBSERVICE affairs control to of the present invention through PB12 with specific embodiment with reference to Figure of description.

Embodiment:

Of the present inventionly realize that through PB12 the characteristics of the assembly of WEBSERVICE affairs control are:

A, the unified transaction object of realization provide client registration transactions object, have unified attribute and method:

Said transaction object connects database;

Database linkage information is set.

B, realization unified data storehouse SQL carry out object, and this object is carried out sql command through transaction object:

SQL carries out object and carries out SQL through transaction object;

C, realization unified data window object, client can be mutual with database through the data window of PB with this object:

Can form the database grammer according to SQL statement;

Data window grammer according to importing into Updates Information.

Shown in accompanying drawing 1, implementation procedure is following:

1. set up the discernible class libraries of Framwork through PB12, client transaction is through this class libraries Register Cancel and operation affairs.

A), comprise at present and carry out SQL object, service data window object etc. according to the different objects of difference in functionality module creation;

A1) it is following to carry out the public function that the SQL object comprises:

A2) the public function of service data window is following:

B) use unified transaction object;

C) externally unified interface object is used in issue, and externally the common interface of issue is following:

2. in Framwork, quote the class libraries that uses PB12 to create, and be issued as IIS

A) according to unified external interface object in the class libraries of PB12 establishment, issue Webservice calls;

B) it is following that the Webservice that issues can call function list:

PbCloseTrans
