An enterprise information integration system

This paper mainly introduces a solution for enterprise information system integration , This article is the material for the actual enterprise patent application ( Has been submitted ), I hope to provide some ideas for you who are writing patents or have doubts in the process of enterprise information integration

The theme

An enterprise information integration system

Existing technology

With the progress of society , Promotion of information technology 、 Digitization 、 The continuous development of intelligence , Various information and intelligent transformation needs within the enterprise emerge in endlessly . Because of the development and informatization planning in every enterprise , All kinds of information 、 production 、 The number of support systems varies , Therefore, the enterprise is in the process of overall transformation , Pull through the data flow of each system to form data sharing , It is particularly difficult to integrate various systems and experiment business process linkage . If we want to realize enterprise information system integration , Nothing more than the secondary development of the existing system 、 Then develop a new system to make a unified portal , Its transformation cost is large , High technical requirements , Many times, it will have a certain impact on the existing system or business .

Existing problems

The import time of various information systems in the enterprise is different , The design concept adopted by the system , Technology Architecture , Technology selection , The degree of opening to the outside world varies . Enterprise information integration should be compatible with and adapt to the technical stacks and protocols of various systems , Difficulty 、 High technical requirements 、 Many times, it will have a certain impact on the existing system or business .

programme

This solution is mainly to solve a lot of repetitive work in the process of enterprise information integration , Reduce the difficulty of technology development , Improve development efficiency .

This scheme proposes an enterprise information integration system , Online data integration is realized by plug-in plug-in and scheduling execution engine , Open interface services , The ability to dynamically extract or subscribe to data from other systems .

The implementation principle of this scheme ：

1. First, according to the database and technology adopted by the enterprise information system , In this scheme, the corresponding data docking plug-ins are designed in advance , such as mysql、sqlserver、PostgreDB、Oracle And other mainstream databases

2. The default plug-in for data flow processing is provided in this scheme system , Such as data diversion 、 logic 、 iterator 、 Script executor, etc , To meet the logical processing and processing of business data

3. In this scheme, the system provides a request access plug-in , Such as HttpRequest、WebSocket、MQ、MQTT、WebServcie etc. , To meet the access needs of different systems

4. In this scheme, the system provides automatic triggering plug-ins in different scenarios , Such as timer ; To solve automatically triggered business requirements , For example, fixed-point synchronization data 、 Automatically synchronize data or automatically execute a process

5. In this scheme, the system provides an online editing console , All the controls provided above support online orchestration and node configuration , And save and publish the arrangement data

6. An execution engine is provided in this scheme system , It is also the core scheduling engine , He runs and deploys the orchestration process released by the console in Hospitality , So as to perform the corresponding orchestration operation

chart 1： The role of enterprise information integration system in the process of system integration

Take an example of a scenario 1:

Sales sign an order for equipment , Data from CRM System entry , Need to sync to SCM Supply chain system , The supply chain needs to judge whether there is inventory , There is no inventory and a production order needs to be issued to MES System , Then the supply chain system will deliver the goods , Financial Invoicing , In this process, we hope to synchronize the torsional state of subsequent systems to CRM System , Let the salesperson know the internal reverse state of signing the order .

Because the internal systems of the enterprise are independent , No system integration , Therefore, the data between various systems cannot be shared , Nor can linkage be achieved , Through this scheme system , Through various functional plug-ins provided in the system , Subscribe to data from different systems , And pass API Interface synchronization data , So as to promote the reversal of data flow and business flow , To achieve the purpose of system integration

For the above scenario , Through this system, the following arrangements can be made

As shown in the figure above , Here is a description of the implementation process of order monitoring

1. Through plug-ins 1,Timer plug-in unit , Set a timer , Send an event every minute , Then drive the following connection nodes

2. When Timer Event sent by plug-in , Pass to the plug-in 2,MySQL（ Query order ） node , This node is connected MySQL data , Execute the SQL sentence , And send the query results to the plug-in of the connection 3（ It is assumed that CRM The system does not support external interfaces , Only direct access to data , And is MySQL Data ）

3. In the 3 A plug-in http-api, Received the first 2 Order data returned by plug-ins , To launch a HTTP Request to send the order data to SCM System ;（ It is assumed that SCM The system provides an interface to return inventory data ） And return inventory information

4. In the 4 A plug-in functionJS Received inventory data , Then judge whether the inventory data meets the order quantity of the order , And back to Y/N The conditional value of ,Y Enter the plug-in 6,N Enter the plug-in 5

5. In the plug-in 5, Received an order without inventory , Then trigger to MES The system issues the request of production order （ It is assumed that MES System support HTTP External interface access ）

6. In the plug-in 4 return Y, Go directly to the plug-in 6, Directly trigger the delivery process of an order （ It is assumed that MES System support HTTP External interface access , And the delivery business is conducted by MES The system is complete ）, After completing the shipment, you can directly enter the plug-in 7

7. In the plug-in 7, Receive the delivery and end the process , Immediately trigger the invoicing process （ It is assumed that ERP The financial system has HTTP External interface access ）, When the billing is completed, the plug-in finally 8

8. In the plug-in 8, Directly update the final status of the corresponding order to invoiced （ It is assumed that CRM The system does not support external interfaces , Only direct access to data , And is MySQL Data ）.

Scene two ： Through this scheme, the system that does not support external interfaces can support external docking and data sharing

such as CRM The system is a relatively old system , It doesn't have Open-API Ability , It is also difficult to transform it , But other systems hope to pass open-api To get the customer information and order information of the system , At this time, we can easily realize through this scheme , As shown in the figure below ：

As shown in the figure above , The whole pass http plug-in unit 、functionJs plug-in unit 、MySql plug-in unit ; Three types of plug-ins have been completed CRM The interface ability of the system to provide external order data , Specific thoughts are as follows

1. adopt http plug-in unit , Configure its type as request, The external interface address is configured as get:/crm/orders; Here you can receive the request and parameters of external system to access the order data , When receiving the request, transfer it to the next node

2. Pass step 1, Get the request and parameters to query the order , Through node 2,functionJs plug-in unit , You can authenticate the request and verify the parameters , Final output Y/N; Return the error code directly for the illegal request , Perform order data query on Legal requests

3. Pass step 2, return Y/N, return N when , Go straight into Http:response node , Return error code , End of request

4. Pass step 2, return Y/N, return Y when , Go straight into MySql plug-in unit , Query the order data according to the incoming conditions , And pass the result set to the next node

5. Pass step 4,http:response The node receives the incoming order data , Directly through response Return to the requester , End of request .
