I am programing a basic P.O.S. (Point of Sale) system, ad am looking for the best way to save Inventory objects. The object contains a few Singles and Strings (Such as barcode, name, price...ect). Assuming the user could possibly input thousands of such items, what is the best way to store and handle these?
My first, and simplest thought, is to add each inventory Item to an ArrayList, then once the user saves, or closes, the ArrayList prints each object to a text file, then when the program opens it reads the text file to re-populate the Array list. However, this seems very un-efficient (I assume). Would it be better to use an excell file or a Database (I know almost nothing about databases, but I can learn), or something completely different?
So I have a list of names in a .txt file. Where is a place I can type in all the names I want and press save and get a link so they can see the list. Then I can remove a name and press save and the name will be gone. And or add a name. So basically I need a website where I can type something and keep it uptodate. I've tried ripway but after you edit the list and save it it doesn't change.

View 2 RepliesI'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.
