Help, programming database

Hi..I am going to program a database for a user. I need to programming it in JCREATOR so that it creates profiles of the students (like name, address, phone... etc) and allow them to update it as they wish...how would I start and program this..
can anyone give me an outline or something?
Thanks

Make a new, larger array and copy the values of the old one into the new one.

Code:

---

Object[] tempArray = new Object[myArray.length + increment];
for (int i = 0; i < myArray.length; i++)
      tempArray[i] = myArray[i];
myArray = tempArray;

---

Every time you add an element, you should check to see if the array is at its limit, and if it is, call a method that makes it larger.

I do suggest learning the linked list method, however, as they offer much more functionality (such as the logical extension of them, binary search trees).
