Hi there I have a database examination tommorrow and there are a few questions that I feel will crop up and I was wondering what the best answer would be to ensure full marks are gained from each one. The questions are:

1. Explain the Logical Structure of a database (3)

2. Explain the Physical Structure of a database (3)

3. Explain the difference in the database approach to file processing as opposed to the traditional approach (4)

4. Define a database using appropriate terminology

I would greatly appreciate some tips
cheers Jay
