how many records can MYSQL 4.1.14 NT via TCP/IP can hold?

how many records per table can MYSQL 4.1.14 NT via TCP/IP can hold?

how many records in a table can MYSQL 4.1.14 NT via TCP/IP can hold given the table has a field Primary key - BIGINT(20) autoincrement?

need your opinion..Here are the facts:

MY system is an internal one. My Server--Is only a Desktop.. Celeron 2.8 Gigahertz, 40Gig Baracuda HD, 512 MB memory.. And it serves an average of 20 users a day and it also serves me for my system development..The average records inserted per month on mYSQL is 10,000 records..We foresee that system would be used for about 10 years.

Create A Database In MySQL To Hold The Videos
I'm creating a website that will (primarily) have thousands of videos. Rather than using a template to create a new HTML page for each new video(i.e. to avoid having to create thousands of HTML pages), I want to use PHP so that clicking a particular video link will 1.

open the (one and only) video player page and 2. get the relevant video file. I've configured PHP/MySQL/Apache/phpMyAdmin and have them running smoothly. I'm not sure if we need to create a database in MySQL to hold the videos(and/or their details) or whether PHP code alone will be sufficient.

How Much Can A Database Hold?
I'm making a website that has a form on it. People fill in the form by entering their personal details (name, address etc) and by answering some questions. When people submit their information, a new row is created in a mysql database stored on the website web space to store their information.

I would like to know if there is a limit to how many people can register, or how much information the table can hold. For example, if thousands of people join, will it always keep adding rows to accommodate this?

Does PHP Have A Way To Export Records Of A MySQL Database?
Quite by accident, I found the mysqldump utility, that comes with MySQL,
which dumps/backsup a database, table, or record. It looks very versatile!

Does PHP have a way to export records of a MySQL database? Anything that
does the same independent of the database used?

Deleting Records From Database
I have another question about record deletion from
database.

For example, my database has 10 records with ids 1
through 10. If I delete id #10 then everything is good
and all the records are still 1 through 9. However, if
I delete record id #4, then in my db I would have
records 1 through 10 with id #4 missing.

Is there a command that syncs the database? How do I
go about this to keep all the ids in the right order
after the deletion? or What do I need to do to prevent
that from happenning?

Incorporating A Rating System To Individual Records In An Existing Database
PROB: Incorporating a Rating System to individual Records in an Existing Database My site, www.recondemand.recset.com is in development and I want to give each record in an existing database that I have created, a rating record (Rating System, i.e. Star System).

So my question is, how do I append/link a Star Rating System Database to my existing Database, so that each record of my database can have their own unique rating system?

More Detail:
main.php
profile.php
player.php

main.php will list several records > once a record is clicked, it will go to the profile.php page to display information (Video title, name, etc.) >

Then when the viewer clicks player.php, the video will play on that page ( I would like the rating system to be incorporated on this page somehow, but uniquely linked with the record it received from main.php & profile.php.

My Hold Function
I'm making a hold function, which calculates time spent working on a job, simply by whether the 'Hold' checkbox is ticked or no. By adding up the times around the hold function, the total time spent can be calculated. There is no longterm storage in PHP tho, so I must use MySQL database to store the stuff. However, if you think about it a little, you realise that the hold times must be able to stack, with no real limit. Does anyone know how I can start to put this together?

P.S. Previously I have queries that select * from database, if I add fields that can hold a LOT of DATES, it'll want to print that stuff with my other useful info. Obviously I could limit my SELECT, but is it possible that data can be stored in the database without it being in an actual field that is usually selected?
