    hello i was wondering if some one could help me out.

    1. i wanted to know if Wpmu-- has only one database or can it have a database for each sub domain.

    if i could have database for each sub domain- i can update each individual database-from a previous setup.

    2. this brings up the second question:how can i update the database of a site-- without affecting the database of the other. example(one wp--has a theme with users/ the other/ has a complete different theme with other users-- how can i update each individual of them, without affect the data or users of the other sub site)

    i have found-- link for structuring database to be scale--how does this work in reference to question #2.

    http://wordpress.org/plugins/shardb/
    http://wordpress.org/plugins/hyperdb/
    https://premium.wpmudev.org/project/multi-db/

    this plugin are not compatible with 3.8 -- some one refer if there is newer plugins for it .

    any help will be highly appreciated

    thanks

  2. I wanted to know if Wpmu-- has only one database or can it have a database for each sub domain.

    WP Multisite runs with 1 database for everything. Once the network gets big enough there are ways to take pressure off that database using the plugins you mentioned. It would defeat the purpose of Multisite if each site in the network has its own database.

    how can i update the database of a site-- without affecting the database of the other. example(one wp--has a theme with users/ the other/ has a complete different theme with other users-- how can i update each individual of them, without affect the data or users of the other sub site)

    Each site in the network has several separate tables. See http://img593.imageshack.us/img593/3414/ej56.png -- it's very well thought out and structured so you don't need to worry about the example you described.

    thanks for the reply --- that makes more sense now

    1.are dose plugins compatible ? with 3.8

    but

    2. how do i insert a database into one of these separate tables ..

    3. if i want to start from scratch -- how do i empty only a specict table without affecting the rest ?

  4. Yes, they work fine with WP 3.8. However, you really won't need to do that until way down the road, unless you already have tens of thousands of sites. You're better off getting high-performance hardware than prematurely splitting databases. There really isn't a single specific point when you need to get into that. If you have that many sites you ought to have a professional server admin to make that decision for you.

    If i want to start from scratch -- how do i empty only a specific table without affecting the rest?

    Start what from scratch? WordPress? Then just get rid of the database and re-install standard WordPress and then convert back to Multisite. If you want to remove specific tables you should use a mysql GUI or SSH.
