- Sub: Should I use TList?
-
- I need some advice on how far to take object oriented programing in writing
- an application. First some background info: we have a large collection of
- video pictures that are stored on a video disk. The video disk can be controled
- by an RS232 interface. We provide an application that allows the user to
- database information about all the pictures then do a search to retreive
- specific pictures.
- The questions: 1) Do I make the database an object? 2)Should the list of
- pictures be a single object or should each item in the list be a seprate
- object?
- My thoughts: I beleive that the database should not be an object. I also
- beleive that I should not make each item in the list a seprate object. The
- list can be very large(1000's of items). Creating this many objects is very
- time consuming. You may not have enough memory to create that many objects.
- Calling the drawing method of each item will be very time consuming. While
- having a TList of objects is very appealing I beleive the overhead will kill us
- in this case.
- What are your thoughts on this?
