A business use case, is a simplified, abstract, generalized use case that captures the intentions of a user in a technology and implementation independent manner.
The system use case has many implementation details embedded within it.
The business use case tells you what your users want to have built.
U therefore can express your requirements as business usecases.
A system use case is describes the system you are going to build to cater the requirement your user has stated in his business use case.A system use case will therefore include high level implementation details like specific references to UI screens if your system has a user interface.
