Ado. net connection environment and non-connection Environment

• Connection Environment: The Connection environment means that the user is always connected to the data source in this environment.

 

Advantages:

> Easy environment security control

> Easy Synchronization Control

> Real-time data is better than other environments

Disadvantages:

> Continuous network connection is required.

> Poor scalability

• Non-connection Environment: In a non-connection environment, some data stored in the central data can be copied and changed independently, and can be merged with the data source as needed.

Advantages

> You can connect to the data source only when necessary.

> Exclusive connection

> Applications in non-connection environments improve the scalability and performance of applications.

Disadvantages

> Data is not real-time

> Data concurrency and synchronization must be solved (important)
