I am very new in WordPress development and I have a doubt about the WP database table named posts
I have observe that when I create a new post (into the WP administration panel) are created 2 record into the posts table.
For example, after that I have create a single post titled as DB TEST into the posts table I found these 2 records:
29 1 2014-08-14 20:36:43 2014-08-14 20:36:43 deb test DB TEST publish open open db-test 2014-08-15 20:37:34 2014-08-15 20:37:34 0 http://localhost/wordpressAsper/?p=29 0 post 0 30 1 2014-08-15 20:36:43 2014-08-15 20:36:43 deb test DB TEST inherit open open 29-revision-v1 2014-08-15 20:36:43 2014-08-15 20:36:43 29 http://localhost/wordpressAsper/2014/08/15/29-revi... 0 revision 0
As you can see the 2 records contains the same informations except for the ID (that is univocal) and for the post_type field. In the first record this field have post as value while in the secondo record the valie is inerith
So why when I create a new post I have 2 records and not a single record?
Moreover I noted that, for other posts, I have more the 2 records related to the same post. What exactly means?
