  1. Hi, This is with reference to your query posted .You can learn but Oracle.But, for web programming, it won't be useful at all.Now-a-days, With VB.net and ASP.net, the programmers are using MS-SQL Sever as the back-end.With PHP - MySQL,With Java, HTML, DHMTL - MS-SQL Server.But, Oracle has its own value.If you know Oracle well, you can learn other Databases easily.I suggest that, first decide yourself which front-end language you want to learn for web designing. Then, decide the back-end.I hope, this is useful for you.If not so, please let me know with the correct info.Waiting for your response

It is confined only to that query. If u want to get the same ou

    It works as well as in the Access.Primary Key doesn't allow repetitions and null values.Foreign key is the reference to the Primary key.
