Common problems related to Informatization Infrastructure Construction

I. Common Problems Related to Informatization Infrastructure Construction

The subject of Informatization Construction in China is Informatization Construction in the industry. Many industries have gone through more than 20 years of Informatization Construction and achieved remarkable results. The following common problems are also highlighted:

1. There are many illegal buildings due to imperfect planning. Informatization is a long-term system project that requires planning at different levels (including the formulation and implementation of standards and norms) and reasonable implementation methods. The planning itself is not in form, but in effect, and needs to adapt to development, in order to respond to the diversified needs and needs at different levels of change. The existing problems are: on the one hand, a beautiful blueprint that cannot be implemented is equivalent to no planning; on the other hand, random planning leads to a low level of repeated construction, and the simple accumulation of various application systems not only has little value-added, on the contrary, many "illegal buildings" are brought with heavy burdens due to problems such as chaotic structures, poor information circulation, and difficult maintenance.

2. The personnel layout and positioning are unreasonable and the output is weak. In terms of construction methods and construction teams, unreasonable layout, inaccurate positioning, and closed-doors car building are found. In addition to the positioning and layout of the construction team on the operation layer of the industry itself, there are still common phenomena that do not fully borrow Social Forces (foreign aid, as a result, the management and technical means such as Project outsourcing and software integration cannot be well used to "take the jade of other mountains" to improve the output and quality of information construction.

3. Do not follow the "Military Strategy" in design and implementation. This problem is embodied in the fact that the system is arbitrarily built and the flexibility of the system is poor.

Randomness is manifested in: the application system is relatively random, the Information Format, system architecture, and the selection of software platforms and tools are relatively casual, and there is no open public technical standard, information encoding standards and specifications are inconsistent.

Poor flexibility is manifested in: the world is changing, and the demand is no exception. However, application systems and subsystems are often tightly coupled with strong dependencies, it is difficult to support dynamic integration of application systems and virtual organization construction. When the demand changes, we have to "patch" and rewrite the software. Too many "patches" often lead to the early death of the application system.

4. quick success. Investment in infrastructure construction is not proportional to investment in business application system construction. The current construction mode is like building a high-rise building on the beach. Without doubling the power of the "Foundation", the building is busy and the room is being decorated. The building is about to collapse after the room has just been renovated, this will inevitably cause unnecessary waste.

After a number of business applications are carried out, information sharing and integration issues are highlighted. The slogan of eliminating information silos arises, and various platform software (often called middleware) that shield underlying heterogeneity) therefore, it is widely used. Large companies tend to push their respective product systems and take the lead of users. The blind introduction of a large number of middleware will lead to new isolated islands. For the informatization construction of the industry, when the number of information and application resources reaches a certain level, the construction of standardized information infrastructure becomes the top priority.

2. Industry informatization infrastructure

The purpose of Informatization infrastructure is "integration", which refers to the following elements supporting Application System Integration:

Network and communication support (including support for ubiquitous computing devices );

A conceptual framework for the application industry, including standards, norms and conventions;

A collection of public resources;

Service-oriented and virtualized public resources (especially general functions) allow transparent sharing and utilization of public resources like power grids and tap water, it includes related planning, models, algorithms, and supporting frameworks;

Infrastructure platform, which provides an operating environment to support infrastructure services including resource management and routing, as well as messages and transactions.

The construction of information infrastructure has a direct and far-reaching impact on the construction of business application systems. Industry informatization construction should begin with its informatization infrastructure construction, which is also the most suitable part for introducing foreign aid in industry informatization.

Iii. Application of Information Grid Technology in Industrial Informatization Infrastructure Construction

The Information Grid technology can be used to build industry information infrastructure, especially infrastructure platforms. Early platforms used socket programming, RPC, and other means to achieve point-to-point interconnection. When there are many points to be connected, it will become messy. Some people compared this interconnection method to "Pasta ". The interoperability platforms represented by CORBA, DCOM, and RMI/EJB gradually replace the non-Chapter interconnection to form the interoperability bus, and have made remarkable progress. The infrastructure platform based on information grid is its continued development, focusing on the word "active" and moving on demand. Sharing does not have to be centrally managed, this has opened up a new way for the construction of information infrastructure in the industry. Unlike traditional operating systems and middleware platforms, the information grid platform breaks the previous "platform is a piece of steel" approach and is a "active" Open Platform in the form of a tool set, it is conducive to resource sharing, reduce repetitive construction, and improve the sustainable development of infrastructure. Specifically, the information grid platform has the following main features:

　　Supports the implementation of super-large application systems in the "virtual organization" mode;

Open Standards support independent hot swapping of distributed and heterogeneous resources;

Real-time combination of applications on demand to meet the needs of various volumes;

Support business personnel to participate in "programming" to better meet complex and changing user application integration needs;

Resources are subject to autonomous control, and subsystems of various departments can be subject to autonomous control;

"Liquefied" data facilitates the smooth flow of data and enables dynamic resource sharing and collaboration;

"Active" basic framework to better support reusable, reconfigurable, scalable, and other features;

"Using millions of people and managing half a person" is easy to manage;

Improves asset utilization through resource sharing and load balancing.

Introducing Information Grid technology to build sustainable information infrastructure is an effective solution to the aforementioned common problems. In this infrastructure, various industries can focus on their business applications. complicated information technology problems will be solved at the infrastructure level.
