At times, you might be compelled to write some code because you think you'll need it. It's just a simple method. If you have a table full of data you'll probably need a GetAll method and a GetById method. A word of caution here: don't write any code until you have a true need for it. The more code that is written, the more code needs to be maintained. If you write code that you think you might need, but never actually use, you've wasted effort. Worse yet, you've introduced code that must be maintained until or unless it is removed.
