Database Question

Can WordPress take entries, fail to write those entries to the database, and still keep those entries on the blog?

The reason I am asking is because I was studying my database for http://totalphysiqueonline.com/ and unless my eyes deceive me, the entire month of Decembers entries is not showing up in my wp_posts datafield. How can this be? Is the wp_posts data field the field that contains all of your entries? Should it contain an entry the instant an entry is posted and saved?

I am new to databases, so all of this may seem elementary to you guys, but I do not trust my level of expertise enough to trust my own eyes, which clearly tell me that there are ZERO entries from the month of December. And December has about 20 entries if you count the ones you see when you visit my blog.

If WP stores entries in places other than wp_posts, then where would I find it. The same thing goes for Bad Behavior. If Bad Behavior does not have a visible datafield that can be seen at the homepage of the database MYSQL home page, then where is the datafield for Bad Behavior hiding?

Go Daddy tells me that the database HAS to be working fine in order for all of my entries for December to be showing up. So……..where the heck are they hiding on the database then 🙂

Thanks
