I'm developing an airline reservation system as my semester project. Here, when one customer books a seat in a specific aircraft, I need to prevent another customer from booking that seat at the same time. I know how to do this in back-end level using synchronization. I need to know whether there is a way to do this in database level. If so, could you please point me in some direction
You can create unique constraint for 2 columns in table like (flight_id, seat_id)

If its just for turning on and off a basic feature, this should be ok?
USER_SETTINGS
-Id
-UserId
-SettingId
-IsEnabled
The problem is some settings require various fields...this could work, but is there a better way to do this?
USER_SETTINGS
-Id
-UserId
-SettingId
-XMLSettings (XML data of settings)
A. you can use nested table or object instead of XML on Oracle
B. you can create another table USER_SETTING_FIELD, which has foreign key to USER_SETTINGS
C. you can use simple string column with the format "field1:value1;field2:value2"
D. you can use extra SettingId for each field

Im curious what is the distinct use of pivot table in database? I mean, how is it apply in real life.
Pivot query help us to generate an interactive table that quickly combines and compares large amounts of data. We can rotate its rows and columns to see different summaries of the source data, and we can display the details for areas of interest at a glance. It also help us to generate Multidimensional reporting.

Can anyone help me to find out Where does TABLE_LIST structure exist in mysql?
And what are the elements it has?
you are totally right, TABLE_LIST is a structure in MySQL source code. its definition is in "mysql-..*\sql\table.h". i think it is used for parsing and optimizing a query. Actually, i want to learn from it very badly. but it is too complicated for me :)
Are you looking for TABLES in the information_schema database?

I would like to know if it is possible,
To extract the userid from an ebay page and insert it into mysql as part of an insert statement? Otherwise what would be the best way to do this?
I have files to import, which contain hundred of ebay auction urls, and I must grab the seller id from each one. Is there an easier way to do this than what I am suggesting?
You could use the eBay API for that. The URL for each page contains an item number, and that can be used to query eBay for the seller id.
eBay Hacks Item 109 gives some PHP example code to do what you need (and more).
