Q:

I'm looking for a free database package for Ubuntu

I need to operate a database for personal use.   Now I'm using Ubuntu 14.04 LTS.  
As opposed to Windows operating system, I'm wondering if there's a dBase, Lotus123 or Access equivalent for Linux?  Something simple like MS Works database would be ideal.  Can someone point me to a suitable package? 

A:

There are numerous Open Source and free database options.  
Popular choices are: 

MySQL and it's successor MariaDB
PostgreSQL
...

You can install them from the commandline with:
sudo apt-get install <mysql-server | mariadb-server | postgresql>

or using the GUI package manager aptitude
