Asked In :-

Right Answer:

ODBC connections use a standard interface that allows for compatibility with multiple databases but may introduce overhead and reduced performance.

2) **Reason for registering a server to the repository**: Registering a server to the repository is necessary to manage and maintain metadata, ensure proper connectivity, and facilitate the execution of workflows and mappings within the Informatica environment.

3) **Rules associated with transferring and registering a server**: When transferring a server, ensure that the server configurations, connection details, and security settings are consistent. Additionally, the server must be compatible with the Informatica version in use, and all necessary permissions should be granted for successful registration and operation.

Dim newThread As New Thread(AddressOf CreateNewObject)
newThread.Start()

Sub CreateNewObject()
Dim myObject As New MyClass()
' Use myObject here
End Sub
```

Tech Architect VB.Net

Ques:- What is the difference between string and stringbuilder?

Asked In :-

Right Answer:
The main difference between `String` and `StringBuilder` in VB.Net is that `String` is immutable, meaning once it is created, it cannot be changed. Any modification creates a new string. In contrast, `StringBuilder` is mutable, allowing for modifications without creating new instances, making it more efficient for frequent string manipulations.
