You'll need to write all the functions in a web scripting language like ASP, PHP, etc. and HTML. So to view, add, delete, update records, you'll need to develop an HTML page in ASP (for example) that interfaces with the DB to do what you want. There are many online tutorials and books dedicated to doing just this.
An example flow of viewing a record in a DB would be:
1) Create connection to DB
2) Query DB for record(s), store returned rows in a recordset
3) Check that recordset has rows
4) Write the data from the recordset to the browser (formatted in HTML).
5) Close recordset
6) Close connection to DB.
So do some research on ASP, and ADO (ADO is the technology used to connect to the DB from ASP - you do not need to purchase anything new, it's installed by default). That should keep you pretty busy. When you have specific questions about ASP code, let us know.
