Design pattern Technique

Hello All,

My question is actually related to design pattern kind off stuff.

As in image, I have 3 layers, UI layer, Business Logic layer and DB layer,

My Question : I want to Design Business Logic layer such that Any UI tech can access, Ex: UI1-Web is a Web Based UI, UI2-Windows is a Windows based UI, And similarly anything else. Whatever the UI technology is, it should be able to consume the Business object, and shouldn't cause any changes in Business logic layer.

How exactly to do this, what programming language needs be used, what technology needs to be used?

Pls help me with as much as detail as possible.
