Qbase is a highly customizable database manager for home users and small business users. You can build your own tables, called "lists", by choosing from a variety of column types to store information such as names, numbers, notes or images, and easily define relations between different lists. Each list can easily be customised by deciding which columns to show or edit, setting filters, sort patterns, color formatting and more. Qbase is a stand-alone solution for Windows and does not require signing up for a cloud account. It is currently a non-profit project available for free.
