In my program (Media database with postgres) I have these classes. Im going to make a Gif class and GifDAO class
These classes all enter the same table in the database (files)
And they only differ by one field in Video and Image Media , and only one method in the DAOs insertMEDIA
My current ideas:
A: Extract a MediaProperties class and inject in the Image and Video constructors
B: Have a File abstract class, and Video and Image extend it.
For the DAO, I thought of a Inserter interface with an insert method, but these DAO would also do other operations, so maybe an Accessor Interface.
Other questions:
Is it a good time to abstract right now? Or should I make the Gif class and wait then, or make more methods (DeleteImage, UpdateVideo), or do a different thing like add the file system to parse Images and Videos for their properties to insert into the database?
