Define a Web database, please. What are the advantages and disadvantages? How do I connect different software to the Web?
A Web database is any database that you can access through the Web. There are no inherent advantages or disadvantages; it all depends upon the way you're using it.
We can connect various programs to the Web by using ASP (Active Server Pages), Perl, application builders such as Forte or PowerBuilder, or by writing embedded SQL code that runs inside another language such as C, Perl, or Java. Most connection are made using either ODBC or JDBC.
