so does statistics mean the calculations of the query plan ?
Did you search in the documentation for the same? Since you didn't bother to mention the version, assuming 12.1, have a read of the following link,
Optimizer Statistics Concepts
Quoting from it,
Oracle Database optimizer statistics describe details about the database and its objects
Aman....

  • What does the term "Wheel" mean under sharing and permissions?

    Hi Everyone,
    When I select a folder (in Applications for example) and then click "get info", under the sharing and permissions section where accounts are listed with their respective permissions, the list usually starts with system or admin, then a term called "Wheel", then everyone. What is Wheel?

    Looks like I'm not having any luck pasting a screen shot...How does one do that?

    wheel is a system superuser group. By default only the root user belongs to it. Snow leopard has changed some permissions and now the preinstalled system apps in the main Applications folder have the group wheel (it was admin in Leopard). I don't know why they did it but this is now normal. where else do you see wheel?

  • I was playing with my ipad settings (it's an older model) and noted in the advanced settings of Safari there was a place to view website databases.  When I clicked on this I saw websites.  How do these get there and what does the space amount mean?

    I was playing with my ipad settings and noted in he advanced settings of Safari there was a place to view "website databases".  When I selected this I saw a multitude of websites.
    Can anyone tell me how these get there?  Can a website be posted even if it was never went to?  What does the space amount mean?  For example, 1.5 kb...is this quite a bit?  Would it indicate someone has gone to a site multiple times?
    I share my ipad with my teenage daughter and I'm trying to find out if she's lying to me.  Obviously she's swearing that she has "no idea" how these got there and I'm trying to keep her safe (she's only 14).
    Thanks everyone.

    Think of your PC and the 'temporary internet folder' where it keeps cached copies of web pages or elements off a web page for 'quicker display the next time you visit'. That's pretty much what that folder is. 1.5K is tiny. Probably just a basic page with some text on it. (you might be confusing 1.5K with 1.5 megabyte....megabyte is large...it's roughly 1000 kilobytes, so the 1.5K is a tiny file)
    As far as I know, the only way info gets into that folder is if the browser has been to that site.
    if you have a concern there are browsers out there, McGruff is one i've seen recommended, that allow some degree of parental control and supervision. That or you could passcode lock the iPad or enable the restrictions to turn off some parts of the device to have some control.

  • What does the word Factory mean in "naming factory "

    What does the word Factory mean in "naming factory" in JNDI tech?

    A Factory class is a class that produces an instance of an object. For example, a ParserFactory class will have a method that returns a Parser. Usually this Factory class is looking at something in the environment to decide which object to return. "Factory" is just one of many "Design Patterns" that you will encounter in the programming world. Several (many?) books have been written about design patterns.

  • What does the plus sign (+ ) mean in the app store updates?

    What does the plus sign (+) mean in the upper corner of the app updates in the app store?  Does it mean it costs more money?

    No, it is free. I have yet to see a paid update. The + sign means it is a universal app, meaning that it works across iPad, iPhone and iPod touch.

  • What does the dotted circle mean?

    When connecting itouch to itunes, what does the dotted circle mean next to a song? Thanks for the help.

    Hi pfn,
    From an earlier post on this topic - this may work for you - it's worth a try:
    First go to the 'On This iPad/iPod/iPhone' section and note all the tracks that have dotted circles.
    In the 'Music' section, un-check/de-select all the tunes noted 
    Apply and sync the changes. 
    Once that completes re-check/re-select the same tunes just un-checked/de-selected in the 'Music' section.
    Apply and sync the changes again
    Go back into the 'On This iPad/iPod/iPhone' section
    Hopefully all the dotted circles will be gone and all the tracks can be played
    See if this helps!
    Cheers,
    GB

  • What does the apple sign mean when sometimes it shows ?

    What does the apple logo mean when sometimes i turn it on it just pops up and goes back to normal??

    Ayip,
    The Apple logo appearing on your iPod nano is your nano's start-up icon. Normally, when you turn off your iPod nano, you are really putting it into a deep or semi-deep sleep, where it is ready to turn on at the push of a button and resume where you left off in your Now Playing list.
    If, however, you leave your iPod in a sleep mode for some time , it will shut down. To turn it on again, you'll need to hit the center button (deep and semi-deep will wake up with any button press). When turning the iPod on from a shut down state, it will display the Apple logo while loading your music iPod software.
    Hope this helps!
    Sincerely,
    -FD

  • What does the exclamation point mean next to a song that is unchecked?

    what does the exclamtion point mean next to a song that is unchecked?

    If you hover over the exclamation mark (or you may need to click on it, I can't remeber), it should tell you. Usually, it means that the original file (for that song) cannot be found, either because it has been moved, renamed or deleted.
