As we all now that using the database oriented programming software such as vfp , vb..... can implement the concept of primary key, secondary key or even foreign key in order to reduce the redundancy of data. That means this can simplyied our way of storing data. Is there any keywords or fucntions that allow such features to be implemented in pascal?
Another question is that, is it possible to implement the concept of relations (e.g. one to one, one to many or many to many) in pascal. That is my question, i hope someone can give me a comment regarding this issue. Thanks!!!!!!
