Hi all;
I would like to know that what is best approch for a photo table that keep photos for an article table and why?
I have a table for articles and each article can have zero or several photos:
1-putting a fileds in article table for photos and put the "file name" of each photo with separator in that field.
2-creat a table for photos and link it to articletable like:
tb_articles|article_id(pk)
tb_photos|photo_id(pk) , photofilename
tb_articles_photo|id(pk), photo_id(fk),article_id(fk
thanks

@MOSTAGHASSI, do not put photos into your data base tables. Instead store the file name of the photo in your data base and store the photos themselves in the server file system. There are many reasons why you want to do this, but performance and back up come to mind immediately.
You can easily generate a unique file name for the photos using a combination of the date/time and the owner key.
If you have many photos per article (zero - to - infinity) you want a separate table of photo names with a key to the articles that the photo applies to.

I hope by "photofilename" MOSTAGHASSI meant file path/to/photo only!!!

Yes ,this is just file name and the file store in a folder.
article_id(pk) , title , subtitle , textbody , source_id(fk) , date , remark
tb_photo

Or
tb_articles
article_id(pk) , title , subtitle , textbody , source_id(fk) , date , remark, photo_file(Comma separated)
