Furthermore, the distributed heterogeneous processing system is in butt joint with the mail system, single sign-on is achieved through the service management platform, and the mail system is logged in a unified mode. The single sign-on is to encrypt the user id, the timestamp and a logic _ secret agreed by the client and the hundred million mail as parameters to obtain an authid, then send the user id, the timestamp and the authid as parameters to an interface/cgi-bin/logic of the hundred million mail for verification, the hundred million mail encrypts the transmitted parameters through passwords agreed by the two parties and compares the encrypted parameters with the authid transmitted by the user, and if the encrypted parameters are the same, the verification is passed.

Further, the smart form platform of the support platform layer is based on the definition, presentation and interpretation of the form of the XFORM standard, and the form build is responsible for realizing the definition and interpretation of the form in the model, that is, realizing the access of information and data, and adopting a component-based description and extension mode.

The component is a software standard component for industrialization of software, is a reusable software component, and can be used for quickly constructing special software prefabricated by other software. The building blocks may be encapsulated object classes, class trees, some functional modules, software frameworks, documents, parsers, design schemas, and the like. The components are divided into component classes and component examples, the examples are generated by giving parameters of the component classes, and corresponding application software is constructed by assembling and controlling the examples. It is essentially a reuse of existing software development knowledge (development process and skills) and the results of the various stages of software development. The component management mainly comprises:

component operation management environment: including the components running services, management environments and business frameworks. The Server provides the running environment of various components, the components run in the Server according to the preset rules, the components operate the data in the XML data bus to complete certain service functions, and the Server provides an API interface and a service component module for the operation of the bottom layer of the architecture, so that a user can call the components in the self-development package conveniently. The method provides a function of managing and monitoring the operation status of the Server and the components, and comprehensively manages the Server through the console.

Component development environment: the component assembly integrated development environment for carrying out patterning and dragging modes on 6 components comprises: developing, debugging, assembling, publishing, and managing an environment.

A component library: the method is directly used for quickly building an application system and is provided with a set of prefabricated parts with high reusability. And a complete software management mechanism of a standardized XML interface for production, improvement, management, precipitation and development of components is provided, and software knowledge accumulation is realized. The system comprises a basic computing component library, a basic service component library and a workflow component library.

In the component, the interface is defined and realized, and the parameters of the interface corresponding to the component are set.

In Sy-FlowBuilder, the component interface parameters can be represented by five-tuple:

component interface (name, processing type, update mode, column set, interface);

the name refers to the user identification of the interface. Interface names in different categories of information may be repeated.

The interface processing types are mainly two types: a maintenance interface and a retrieval interface. The maintenance interface refers to an interface interacting with a user in the business process, such as an interface corresponding to draft making, draft checking, issuing activities and the like in a text; the retrieval interface is an interface interacting with a user when retrieving data, and comprises a retrieval condition input interface, a retrieval result list, retrieval details, retrieval statistics and other interfaces. In fact, information retrieval does not belong to the office business processing process, but various retrieval interfaces are different due to different processing businesses. The definition of the search interface is also done by the workflow model designer. The maintenance interface is typically update-enabled, while the retrieval interface is read-only.

And the updating mode indicates which database table is updated when the component corresponding to the interface needs to be updated. Since an interface may be composed of fields in multiple database tables, it is necessary to indicate which table needs to be updated.

A set of columns refers to all the fields contained in the interface that correspond to fields in the database table. To facilitate the work of the workflow model definition personnel, each field is represented by a Chinese name. The column set describes the behavior at all field levels on the interface during workflow processing. In the following section we will describe the definitions of the columns in detail.

Interface I ═ retriverow, GetFocus, LostFocus, EditChanged, ciiked, valid, Updated, Express };

it is described as follows:

table 2 build interface definition table

The form generator: used for generating a form; and corresponding to Form \ Page elements and other related parameters, using OUT during generation. Generating an object; objects such as text, datetime, listbox, dropdown, combbox, textarea, button, submit, select, tree, and radio checkbox are included, and the parent-child relationship is organized according to the attributes of the objects; forming a series of controls;

searching the form receiver: for receiving submitted form data; receiving all data objects from the Request, querying required fields from the Form for matching, and submitting corresponding data to a data source object; performing operations such as insertion, modification, deletion and the like of the database;

the data source object: data query results, modification, deletion and insertion of data; data modification, deletion and insertion are all waited by a specified database script, and the data parameter sequence and the parameter name are independently set to adapt to different databases and programming languages;

the search form analyzer: XML definition file for solving form; after the analysis, the form object is loaded to the corresponding form object.

The information standard management is continuously supplemented and perfected with project construction, and is mainly used for importing, maintaining and releasing information standards;

the reference information encoding set includes at least: the national standard, the central intelligent campus standard, the national institute of administration standard, the provincial standard and the intelligent campus standard are continuously released by new versions along with the reference information coding, and need to be continuously improved;

the calibration information criteria set includes at least: the intelligent school management information subset, the daily office management information subset, the student management information subset, the teaching and educational administration management information subset, the instructor, the retired person management information subset, the financial management information subset, the book, the file management data subset, the logistics service management data subset and the alumni management information subset;

the information standard and metadata management provides a standardized data interface for the platform, and at least comprises: metadata management, formulation and initialization of an information standard code set, formulation of an information standard set and release of an information standard.

The sub-organization is a branch organization with independent administration capacity, and is a part of branches divided from the organizational tree. Units at all levels of the intelligent campus in Jiangxi province can be set as sub-mechanisms.

Each sub-organization comprises a part of departments and users on the organization tree of the whole system of the intelligent campus college of the western and the river provinces, and conversely, the departments and users on the organization tree of the system of the intelligent campus college of the western and the river provinces must also designate the sub-organizations. Each sub-organization may set up an administrator to implement hierarchical management.

Each sub-organization may have its own home page, specific business modules, specific flow sheets and menus, etc. All data related to the sub-organization are marked with the sub-organization ID attribute so as to ensure that the data are private to the sub-organization and do not interfere with each other. Each sub-organization may use the data of the sub-organization and the common data.

The organization and user data belong to private data of sub-organizations, and except for the provincial wisdom campus of the root organization, each sub-organization cannot access the user data of other sub-organizations (except for cross-unit flow).

The business module can be public (all units in the whole province can use the business module) or private, and the private module can authorize all sub-organizations to use the business module. Thus, each sub-organization can have different business modules according to business needs.

The process data flow can be public (all units in the province use the process by default) or private, and the private process can authorize each sub-organization for use. Therefore, the same module of each sub-mechanism can also go through different processes according to the business needs.

The form (print) data may be public (which is used by all institutions in the province by default) or private, which is authorized to various sub-institutions for use. Therefore, the same module of each sub-organization can display forms (printing forms) with different styles according to business requirements.

The code data can be public (all units in the province can be used) or private, and each sub-organization can maintain the private code of the sub-organization.

Allowing different sub-organizations to use different styles of menus, as well as different menu items.

Allowing different sub-agency configurations and use of different home pages.

All kinds of service data generated in the system operation are private data of each sub-organization, and except special conditions, other sub-organizations cannot access the data.

The distributed heterogeneous processing system adopts WS-Security and WS-Trust specifications, and FIG. 3 is a system operation environment deployment diagram of the distributed heterogeneous processing system based on workflow, and a Web Service technology is adopted to realize core components in the system.

WS-Security describes enhancing SOAP messaging, providing quality of protection through message integrity and message confidentiality. This specification also defines how security tokens are appended and contained within SOAP messages. Finally, a mechanism is provided for specifying a binary-encoded security token (e.g., an x.509 certificate). These mechanisms can be used independently or in combination to provide a wide variety of security models and encryption techniques.

WS-Security provides a generic mechanism for associating Security tokens with messages. WS-Security does not require a particular type of Security token. It is designed to be extensible (e.g., to support multiple security token formats). For example, a requestor may provide proof of identity and proof that they have a particular business certificate. One way to provide message integrity is to use XML signatures with security tokens (which may contain or imply critical data) to ensure that the message has not been modified during transmission. The integrity mechanism is designed to support multiple signatures (possibly signed by multiple participants) and can be extended to support additional signature formats. The signature may reference (i.e., point to) a security token. Also, one way to provide message confidentiality is to use XML encryption along with a security token to keep a portion of the SOAP message secret. The encryption mechanism is designed to support additional encryption techniques, processes, and operations by multiple participants. Encryption may also refer to a security token. Finally, WS-Security describes a mechanism for writing binary Security tokens. This specification also describes, among other things, how to write X.509 certificates and Kerberos tickets and how to include opaque encrypted keys. It also contains an extensibility mechanism that can be used to further characterize the security token contained with the message.

WS-Trust will describe a model for building direct and proxy Trust relationships, including third parties and intermediaries. This specification will describe how existing direct trust relationships can be used as the basis for proxy trust by creating a security token assurance service. These Security token assurance services are based on WS-Security, delivering the necessary Security tokens in a manner that assures the integrity and confidentiality of the tokens. This specification will then describe how several existing trust mechanisms can be used with this trust model. Finally, this trust model will explicitly allow, but not force, principals to authorize delegation and impersonation. Note that delegation is consistent with impersonation, but it provides an additional level of traceability.

The WebService adopts a protocol comprising XML: the Extensible Markup Language (Extensible Markup Language)1.0 standard is a Markup Language based on the text World Wide Web Association (W3C) specification. Unlike HTML, which uses tags to describe appearance and data, XML strictly defines portable structured data. It can be used as a language for defining a data description language such as markup syntax or vocabulary, interchange formats and communication protocols.

SOAP: the Simple Object Access Protocol (Simple Object Access Protocol) is an XML-based lightweight Protocol for exchanging information in a decentralized, distributed environment. SOAP defines a communication protocol between the requester and supplier objects such that, in an environment where object-oriented programming is popular, the application object performs a remote method call on the provided object. The SOAP specification is jointly developed by Microsoft, IBM, Lotus, UserLand, and Developmentor. The specification was subsequently developed and established the W3C XML protocol working group, in which over thirty companies participated. In SOAP implementations of most vendors, SOAP builds the foundation for distributed object communication. Although SOAP does not define a communication Protocol, SOAP has recently been referred to as an object-Oriented Architecture Protocol (Services-Oriented Architecture Protocol) due to its common use in SOAP implementations. SOAP has the advantage that it is completely vendor independent and can be implemented independently from the platform, operating system, object model and programming language. In addition, the transmission and language binding and the choice of parameters for data encoding are implementation dependent.

WSDL: the Web Services Description Language (Web Services Description Language) is an XML vocabulary that provides a standard method of describing a service IDL. WSDL is the product of the convergence of activities between nassl (ibm) and sdl (microsoft). It provides a service provider with a simple method description application form and responds to remote method invocation information (RMI). WSDL does not rely on the underlying protocol and coding requirements to refer to the subject matter of the service IDL. In general, WSDL provides an abstract language to define published operations with respective parameters and data types. The language relates to both the definition of location and binding details for the service.

UDDI: the Universal Description, Discovery, and Integration protocol (Universal Description, Discovery, and Integration) provides a common set of SOAP APIs that enable a service broker to be implemented. The UDDI specification is formulated by IBM, Microsoft, and Ariba to facilitate the creation, description, discovery, and integration of Web-based services. Org (a partner and cooperation between over 70 industry and trade organization leaders) is motivated by defining a standard for B2B interoperability.

the cluster built by the database realizes the security guarantee of data through Oracle Dataguard, and referring to the attached figure 4, the cluster is a database configuration diagram of the distributed heterogeneous processing system based on the workflow.

The major function of the Dataguard is disaster redundancy, the standby database automatically maintains the standby database through the filing log (or redoing entries) transmitted by the production library, and keeps the consistency of the data of the production library and the standby database, so that when the production library fails, the original standby database can be immediately switched into the production library, the system can be quickly recovered to be normal, and no real-time data loss exists after switching. After the fault production library is recovered, the fault production library can be used as a new standby library to synchronize data with the current production library.

The Dataguard adopts a maximum performance mode which is a default mode and can ensure the highest availability of the main database; the main library is guaranteed not to be influenced by the standby library in the running process, the main library transaction is normally submitted, and the running of the main library is not influenced by any problem of the standby library;

Fig. 5 is a workflow management system model diagram of a distributed heterogeneous workflow-based processing system according to the present invention.

In this reference model, the following five parts are co-classified:

1) process Definition Tool (Process Definition Tool):

it provides software for describing workflow process, describes the actual process steps with visualization method or simple text and generates or converts them into the standard workflow definition language format;

2) workflow execution service (workflow execution service):

it is composed of one or more workflow engines (workflow engines), which are the core of the workflow and responsible for creating, managing and executing workflow instances. The workflow engine is an execution environment of the workflow instance providing runtime, and explains the process definition, controls the operation of the workflow instance, navigates the workflow according to the definition and the state of the workflow, assigns various roles, maintains the control data of the workflow, calls various applications, and the like; various workflow applications access it through a Workflow Application Programming Interface (WAPI). Logically it provides a total of 5 interfaces, see in particular the interface description below;

3) direct call application (invoked application):

it is a collection of functional applications, each of which may be responsible for completing the execution of a certain sub-process of a workflow or for completing a certain task(s). The workflow engine calls the workflows according to the running conditions of the workflows to complete the execution of the workflows;

4) client application of workflow (workflow client application):

it can access the workflow list (workflow) library through the workflow list access interface (workflow access), and the workflow engine can assign the work (task) to the workflow list library and the user can access to accept the assigned task. Workflow client application components are optional when implemented, but some less than fully automatic process in requiring involvement in completing a workflow is for the application to provide the application;

5) workflow management and monitoring Tools (Administration & monitoring Tools):

it is responsible for managing monitoring workflows, including user management, role management, run records, error recovery, stopping and deleting workflows, etc.

The workflow execution service is the core of the workflow execution service, and communicates with other four interfaces, wherein the 5 interfaces are respectively:

interface 1 Process definition and workflow service Interface (Builder-Server Interface)

A common format workflow process definition language for static process exchange specifications is defined between the process definition job and the workflow server. Such as XPDL (workflow definition language).

Interface 2 Client-Server Interface

Complete interaction is provided between the workflow client and the workflow server, including operation of the workflow list, querying, control of the workflow process and its activities, and management functions. It also allows a workflow client application of one vendor to access a workflow server of another vendor.

Interface 3 application invocation interface (application invocation interface)

Temporarily not used.

And interface 4: interface between workflow server and server (server-server interface)

The interaction between two workflow servers is described, including the control and management functions of the initialization, query and workflow processes and their activities, etc.

And interface 5: interface of monitoring and workflow server (monitor-server interface)

A set of functions for managing and monitoring the workflow server is defined.

The distributed heterogeneous processing system based on the workflow can flexibly and conveniently set the corresponding workflow according to the requirements of business handling and document processing, and can provide a graphical interface of the workflow. The flow setting can meet the processing requirements of business handling and administrative official documents. Based on Web Service and XML, the system has good openness and expandability. The Web Service and XML technologies are important technologies and tools for realizing openness and system interaction, and IBM, Microsoft, SUN and the like support the two standards to the utmost extent although the platforms and languages are not unified. As a standard of function calling and data exchange, our Sy-FlowBuilder realizes the function calling based on Web Service, and accords with WFMC specification on function design, while Sy-FormBuilder and remote data exchange describe and transfer data by using XML language, which means that the system has good openness and expandability. The process planning can be easily completed based on the Web graphical process making function. Through Internet or Intranet, Drag and Drop (Drop) graphical task grouping and a superior supervisor or relationship person can easily establish a form flow chart in a browser.

The workflow-based distributed heterogeneous processing system comprises the following specific steps: supervising or urging according to the handling requirements; automatically urging and supervising the files after the file is overdue; reminding the case, and informing the transacting personnel to transact the case in time.

(1) Local handling monitoring

The leader of the department can monitor and urge the case handling situation of the department (if necessary, the superior can also urge the subordinate to issue an order within the specified time limit)

The department monitors and displays the inquiry statistical information (including cases and quantity to be handled, cases and quantity in handling, cases and quantity due, overdue and quantity, urging conditions and the like) of the incoming documents handling in the department, and can also inquire the handling conditions according to personnel.

The department monitoring only has monitoring and supervising rights to the department and does not have supervising rights to the whole process.

(2) Whole-city handling monitoring

The monitoring personnel can monitor the running condition of the process.

1) In the case handling process, the system can automatically prompt cases with different progresses in a grading and fractal mode (the prompting mode requires striking, such as: red differentiation can be added when the file arrives; the handling time limit can be changed into a striking color automatically with the file title 1 day before the completion; file expiration, which may occur in a scrolling manner, etc.; if the file is overdue and not processed, the first line is referred to and the file is reminded in a flashing and striking way. )

2) And inquiring and counting the case handling conditions. And counting the case handling conditions according to requirements, such as displaying specific cases of files to be handled, files at work and due and files at overdue and counting summary numbers.

3) The operation monitoring personnel can monitor the operation condition of each process (namely, the operation monitoring personnel can monitor which node, which nodes are circulated and which nodes are required to be circulated in each case at present)

4) If the examination and approval work cannot be completed within the specified time limit, the system should have a corresponding prompt in the window, and the host department fills in the delay condition. The business process explains the situation to the applicant. The system should also be able to automatically notify the applicant of changes in the transaction time. Such as the EMAIL mode.

5) All the time of the system working is subject to the time of the server.

The system management personnel can carry out special treatment on the flow to ensure the correct operation of the actual business handling process, and the method further comprises the following steps: flow delay: changing the processing time limit of the flow; suspending the flow: suspending the process handling and stopping the timing of the case; and (3) deleting the flow: clearing the whole flow; and (3) hastening: in the case handling process, the monitoring system should automatically (or manually) send out an office sheet for the nodes exceeding the time limit. And for the nodes which do not exceed the time limit, the system can also promote the nodes according to the requirements. The function of reassignment: the system administrator can directly re-assign the forms to other users on the flow chart, and solve the problem of form processing state stagnation or delay.

When a fault occurs or a fault call is received, emergency group workers need to accurately record related contents and timely report emergency group leaders. When the smart campus platform and the important computer network cannot work, the technical support department needs to be reported in time. After the fault is eliminated, the emergency working team staff must report to the emergency working team leader in time and fill in the fault processing record. The staff in charge of document management must do the work of filing for receiving and reporting faults and eliminating records.

The emergency working group staff must carefully perform their respective duties and strictly execute the reporting system according to the pre-arranged plan. In the process of fault elimination, the mobile phone of a person participating in the fault elimination work needs to be turned on for 24 hours, and if the mobile phone fails, other methods capable of timely communicating need to be provided.

When the computer backbone network of the intelligent campus platform has faults (the system cannot operate or the response speed of the system is too slow), if the faults are not eliminated within 1 hour and the system is in the working time, all the using departments involved are informed by an emergency working group so as to take necessary measures.
