Small Business Database

Hello,

I am completely new to all of this and looking around for help. I recently started a (very) small business and i want to use OpenOffice to help run it.I'm looking for a pre-built database so I won't have to start from scratch. I have built databases before, but just looking for a time saver that I can tweak.  I have looked for help Online marketing ads but can't find where you have put the support for this problem.The options I have found online are templates for specific documents or tables and I'm looking for a small business application. If anyone can point me in the right direction .I went through many resources but did not find any solution for this issues. Please help me out.

Any help will be appreciated.

Thank you.
