Kekeguo brings you the core key test site of soft exam information system project manager （ 8、 ... and ） Software integration technology , Including mind map + The real question . This data is sorted out by Keke .

【 Information system project manager core examination site 】 Software integration technology

In the enterprise information construction , Due to the lack of unified planning and overall layout , Often form multiple information islands . Information island makes the consistency of data impossible to be guaranteed , Information cannot be shared and fed back , It requires repeated acquisition and input . Information island is an important negative factor of enterprise informatization , The main reasons are both technical factors and management factors , There are also factors in business processes and Standards . How to connect many isolated information islands , So that different information can interact with each other , It is a problem faced by many enterprises at present .

Enterprise application integration （Enterprise Application Intergration,EAI） Technology can eliminate information islands , It connects multiple enterprise information systems , Achieve seamless integration , Make them as a whole .EAI It is produced and evolved with the development of enterprise information system , The value orientation of enterprises is to promote EAI The driving force of Technological Development , and EAI In turn, the realization of also drives the promotion of enterprise competitive advantage .

EAI The connected applications include various e-commerce systems 、ERP、CRM、SCM、OA、 Database system and data warehouse . From the perspective of a single enterprise ,EAI It can include presentation integration 、 Data integration 、 Control integration 、 Business process integration and other levels . Of course , Application integration can also be carried out among multiple enterprises .

【 Software integration classification 】

1、 Represent Integration

Presentation integration is also called interface integration , Gather the original scattered system interface into a new interface . Indicates that the integration is a black box integration , There is no need to understand the internal structure of the program and database , The commonly used integration technology mainly consists of screen capture technology and input simulation technology .

2、 Data integration

In order to complete control integration and business process integration , We must first solve the problem of data and database integration , Before integration , The data must first be identified and catalogued , Then determine the metadata model , Ensure data distribution and sharing in the database system . Data integration is white box integration , The integration point is middleware .

3、 Control integration

The integration point of control integration is stored in the program code , Integrate the application system in business logic , Also called function integration or application integration . Integration may only require the simple use of public API You can access . Control integration is black box integration .

4. Business Process Integration

Also known as process integration , By a series based on 【 The standard 、 Unified data format 】 The workflow consists of , Enterprises must define the exchange of various business information 、 Empowering and managing .

【 Mind map of core test site 】

【 Core test site real questions 】

1. Application integration within an enterprise can include presentation integration 、 Data integration 、 Control integration and business process integration , Description of the relationship between these integration methods , What's not right is ：( ).

A、 When the business logic is relatively stable , Data integration is more flexible than presentation integration

B、 Control integration is more flexible than representation integration and data integration

C、 Data integration is more complex than control integration , The complexity of control integration is higher than that of representation integration

D、 Business process integration is the most complex , This integration goes beyond data and systems

【 answer 】C

【 analysis 】 Information system project manager tutorial No 3 edition P55, Software integration technology C: Control integration is more complex than data integration and presentation integration

When realizing control integration , You can use remote procedure calls or remote method calls 、 Message Oriented Middleware 、 Distributed object technology and transaction monitor . Control integration and presentation integration 、 Data integration , More flexibility . Represent the environment where integration and data integration are applicable , Are applicable to dry control integration . however , Riyu control integration is carried out in the business logic layer , Its complexity is higher - some . and , The business logic part of many systems does not provide API, such , Integration will be more difficult .
