Is this project a good idea - interfaces and abstract class

Question

I would like to be able to do something like the following:

//non-generic
var MyTable = new Table();
string name = MyTable.Name;
IEnumerable<String> rows = MyTable.Rows;

//generic
var MyTableGeneric = new Table<MyType>();
string name = MyTableGeneric.Name;
IEnumerable<MyType> rows = MyTableGeneric .Rows;

Something like this will be a lot:

or it will be better:

Sorry if it's hard to understand what I'm trying to get to, basically I have two objects that will share comman properties, except that the string collections will be universal. I would like to do this in the cleanest way.

Sorry for my crappy diagrams made at powerpoint :)

Answer 3

I would use generics in strings without involving a string in the base class and have a non-generic type of the inherited class Table. Do not use an abstract class.

Table<T> -> Table:Table<string>
