In the development process of enterprise network application, the planning and establishment of network system integration scheme is an important basic part of enterprise network application. Therefore, the network system integration scheme should be designed according to the actual needs and in combination with each part for the purpose of improving enterprise efficiency and creating higher benefits. The following principles should be followed in the design of enterprise network system integration scheme:

(1) Practicability

In the network system integration scheme, the network system is set for the purpose of user use, and attention should be paid to its practicability to meet the use needs of users.

(2) Security

In the network system integration scheme, the computer network system should be security oriented. The low system security is easy to be attacked by viruses / hackers, so that the data information is stolen and the interests of users are damaged. Therefore, network system integration should have better prevention and recovery ability against network attacks to maintain user information security.

(3) Reliability

If a part of the system fails during operation, it will affect the whole network system. Therefore, we need to ensure that the system can meet the needs of users in a short time, buy time for maintenance personnel and improve the reliability of the network system.

(4) Scalability
When designing the network system integration scheme, it shall ensure its reliable use performance and good scalability, so as to facilitate future updating and expansion, so as to adapt to the development of information network and user needs.
