The Arrival Of Enterprise'S Full Information Age -- Integration Creates Value, And Integration Leads To Intelligence (4).

Because all applications are focused on application servers, deploying new applications or upgrading software is directly done on the application server without having to go to the client side by side.

Data backup and data update are similar, and can be done centrally on the database server.

Correspondingly, the mainframe technology is characterized by the application and data stored in the mainframe, and the client terminal using the character terminal.

The disadvantage is that the interface is not rich and flexible, it is difficult to express multimedia data such as graphics and sound, and the mainframe hardware is expensive and has poor expansibility.

The characteristics of client / server technology are separation of application and data, client application and server side storing data.

The disadvantage is that the amount of network communication is large, and it is not suitable for WAN. The more serious is that its application is distributed on every client. Installation, upgrade and maintenance are complex, and the cost is high, so it is difficult to adapt to the requirements of Internet application.

The application of C/S structure is difficult to realize the centralized management of enterprises across regions, or it will inevitably cost expensive promotion and subsequent maintenance.

2. uses cluster database technology to save investment in hardware and ensure that enterprise information exists in a single database.

The data capacity bottleneck of hardware and database has plagued the information construction of enterprises.

The old solution of enterprises is to continuously add piles of servers and distribute applications on multiple databases on multiple servers.

The present method is different, for example, the Oracle 9i database uses Real Application Clusters, which enables a single database to run on multiple servers at the same time without any modification to the application code or architecture. This feature greatly improves the system reliability: if the data capacity increases, the enterprise can expand by adding small servers, and will not damage the system when any server fails, because other servers can easily share some new loads.

This feature can also shorten database access time and improve application performance.

It also makes it possible to replace expensive mainframes with IT data centers made up of more inexpensive computers, which can save nearly 80% of hardware (in some cases, millions of dollars) as the demand for CPU increases.

The Oracle database now occupies more than 66% of the Unix open system. It provides excellent open performance and leads the current database technology standards.

The adoption of advanced integration technology 3..

In the ideal world, each person adopts a unified standard, and uses unified application software and auxiliary development tools to establish enterprises, so that different systems can communicate like a system.

But in today's e-commerce world, this is not the case.

A globalized enterprise can make it work towards an isomorphic environment, but in view of the fact that it is necessary to exchange data with external databases and enterprises, let alone merger and subsequent information integration nightmare, any technology that is not flexible in business environment can be fatal.

Under the Internet computing structure, the task of integration is mostly undertaken by the application server.

The Oracle application server can use the integration tools and methods to talk with the source system.

For example, it can talk with the host, communicate with the communication system, dialogue with Oracle and non Oracle database, dialogue with application packages, and dialogue with switches and Web services.

We can see that the application server can talk with many devices.

This is why we use our integrated device and make it an integral part of the application server.

To meet challenges, the integration technology provided by Oracle is becoming increasingly mature.
