resource for finding data models for projects you may have or as examples of well put together data
models. With around 500 data models the chances are you find something at least cl...

Hello: I am new to JAVA and server-side applications and have a dumb question. I have set up
Tomcat on my machine and created a JSP program to query an Access database using a DSN-Less
connection. If I publish the page to a webserver and include the .MDB file will it work? I'm
not sure exactly what needs to be packaged with my Java application to make it work. Since I
don't have a remote server that supports .jsp I cannot really test it. I'm assuming that
JDBC driver would be bundled with my site but not sure. Thanks!...

in using it. It wasn't until about a year and half ago now that I was first introduced to this
new age of Database. I discovered a lot of neat things and even learned about databases the very
long way. A database is exactly how it sounds its data that has a base. The base being the place
where you store all your data. If you have ever been to a library perhaps you have used the Index to
search for an author, this is a database of authors. Ever seen a rolodex on someo...
