Abap Objects With or Without persistence

[Former Member]

Hi forum!

I'm looking for examples of abap OO programs with BD interaction using persistence or not, when do you suggest to use persistence in abap programing?, and, when i do easy reports?, i'm working in R3 enterprise 4.7 basis 6.20.

Thanks in advance,

John.

I think it depend on your requirement.

I have some experience on persistence class.

It will generate a class combine with a table, and you can populate the table with this class, include select, insert, modify.

It offer you a way to populate table in a OO way.

But unfortunatly, single persistence class can only combine one table. And after you save the combine relation of the class and table, it is difficult to do further change.

So if your application need to populate multiple table in same time, and do some join select, persistence class won't help too much.

I think BO (business object) will be helpful to you.

If you don't want to access the relate table directly.

But BO is not a OO way.

thanks
