Hello to all i need some information about how to make a database

Hello, Hesam, A database is just a collection of data. Databases come in many shapes and sizes. A simple text file can be used as a database; some use a spreadsheet such as Excel as a database; Access is a popular Windows database; Sybase and Oracle are more heavy-duty databases used by some larger businesses; and on and on and on. What are your needs? What type of data are you going to be storing in your database? What are your data retrieval requirements? How many people will have to have access to the database? How will the database be accessed? What will you be using the database to accomplish? Give us a little more to go on, and I'm sure you'll get lots of responses.

i need to write a database for an assignment, and don't quite follow how it is done. i have searched through the net and found nothing. so i am hoping for a little help from here. im programming with c++ and have to write a database that will keep track of computer inventory (serial numbers, id numbers, type, cpu speed, etc) so if any one can email me with some help or just post it, then it would be greatly appreciated.
