EAI concept
Enterprise information construction, after decades of fast IT innovation creates a large number of comprehensive, distributed and changing application systems, these systems span different systems from large machines to web, so different systems Interconnection has been a problem that needs to be solved. How to play the potential advantages of these corporate assets, make full use of existing technologies and application resources, and enterprise application integration (EAI).
At present, more and more enterprise users are being bothered for application integration. According to statistics, in most companies, 80% of IT resources cost the infrastructure development, integration and maintenance, this means that only 20% The IT budget can be used to enhance the competitiveness of the corporate market, bringing high-value applications for companies, this is not to be a nightmare! Why is the infrastructure so expensive? This is because the increasing application of enterprises is distributed on a variety of different platforms, making information integration between different systems into a heavy burden of enterprises. On the one hand, in order to use IT technology to acquire competitive advantage, companies hopes to be able to deploy various applications efficiently, including new web applications, support Web original systems, online transactions, enterprise portals, mobile and wireless access, business process automation, Commercial partners are connected, realize business intelligence, etc., on the other hand, the internal application system is too complicated, there are too many components, the infrastructure is unreliable, unmanageable, and integrated infrastructure requires a long time and expensive fees. This complexity uses the households in IT investment, so that IT technology has not been played far in improving efficiency and costing costs.
EAI technology is considered to be the key to success in the company. Integrate all the information resources of a body into a seamless, parallel, easy access to corporate assets, which makes a powerful corporate asset operation. Just like a virtual single system. EAI contacts the heterogeneous system, application, data source, etc. of the entire enterprise through the underlying structure, and completes seamless sharing between ERP, CRM, SCM, database, data warehouse, and other important internal systems within the enterprise. Exchange data needs.
China Netcom Integrated Business Support System Overview
China Netcom integrated business support system is a new generation of OSS / BSS systems. This is not only for the relevant independent core business system itself, but also as an important basic system in the overall IT architecture of Netcom, its construction will have a profound impact on the overall operations and management architectures in Netcom's in the next few years.
China Netcom has many product lines in voice and data business, but there is no unified support platform, and a large number of business processing is hand-operated, whether business operations and business management are greatly restricted; a lot The business system is still manually completed, or writes a large number of follow-up code to complete data interaction; voice service and data services are isolated from each other, and there is no unified interface for marketing and cannot promote each other. How to effectively support the integrated business of voice and data, become the key to the success of Netcom.
Netcom Integrated Business Support System Supports Netcom's existing voice and data services, and features integrated marketing acceptance, order scheduling, business management, certification authorization, collecting billing, settlement processing, comprehensive accounting, payment, customer management, product Management, agents management, etc., serving the headquarters direct sales department, business management department, and branch office.
The following figure is a framework structure of the integrated business support system:
Overview of China Netcom EAI System
Construction Netcom integrated business support system requires considering the integration and interoperability of new systems and the original systems. On the other hand, operators need to transform existing systems or business processes to adapt to new business needs to protect the original investment, reduce costs, which requires new systems to fully consider business process changes in the construction initial. Therefore, it is necessary to build a complete, safe and reliable EAI system, integrate a wide variety of separation business systems, unify the external interface of each system, implement the data intercom, operation integration forming a unified operation. Relying on the EAI system to implement the unified coordination, data processing and business process of internal business processes and external business processes, to adapt to flexible business needs, thereby implementing corporate management level, operating efficiency, service capabilities, etc. Overall improvement. China Netcom's EAI system (linkage system) is an important part of China Netcom Operation Support System Plan, which assumes the application integration of the entire OSS / BSS system. Through the EAI system, the data interaction and interoperability between each function subsystem is completed, and the grading architecture, complete, safe business support joint system is gradually formed. By building an EAI system, support for business restructuring, system integration, and data sharing is largely provided, and the goal of reducing costs and enhance market competitiveness is achieved.
China Netcom EAI system specific construction goals:
- Connect various functional subsystems and external related systems in China Netcom Integrated Business Support System
- Integrate business processes for each system, form a more standard, customizable process management platform
- Integrate data in each system to form a more standard data model
- Establish a connection interface to each system, develop and implement these interfaces
- Establish data transfer channels of enterprise data center through data integration and transfer
The core platform of the Netcom EAI system uses Microsoft's BizTalk Server. The BizTalk data bus mechanism is used to maintain both independence and can also be flexible; through a flexible transmission protocol definition, data format conversion, call convention setting, etc., the various business modules are scheduled, and the services are guaranteed High reliable stable, safe connection between the subsystem, and monitor data connection; use XML as a data exchange model, it is independent of the running platform and the specific development technology, thereby ensuring the openness of the system, it can be easy Realize the expansion of future new services; support real-time and asynchronous transmission mechanisms to ensure the transaction of the process, maintain data consistency.
The following figure is a schematic diagram of the Netcom EAI system:
The construction of Netcom EAI system runs through the whole process of construction of integrated business support system
The construction of the EAI system is closely integrated with the construction of various business subsystems in the integrated business support system. In order to achieve various separation business systems, unify the external interface of each system, implement the overall goal of the data intercommunication, operation interoperability, EAI system organization, coordinate the relevant business subsystem, and completed the "various subsystem functions" , "Subsystem-cross-system business process integration", "interface definition", "interface development", "integrated test", etc. Good foundation.
During the construction of the EAI system, the system constructor and related business units (such as enterprise customer clients, operational services, services and implementation and implementation and implementation and implementation, etc.) have maintained a good communication mechanism, clarify business norms to ensure integrated support systems Process and good support for future new services.
Netcom EAI system construction experience
Combined with the practice experience of system construction, the success of EAI system construction and two factors: one is the advanced technology, reliability, safety, flexibility of EAI system itself. Another factor is the clear and stability of business needs, it directly affects the effects of cross-system business process integration.
With the increasing development and maturity of China Netcom, Netcom EAI system that is an important part of the integrated business support system will also gradually develop and improve.
