Copernica databases can be layered, allowing you to, for example, store purchase histories. It is also possible to make [selections](./selections- introduction) which can be used for the segmentation and personalization of your email campaigns. Copernica stores a lof of data about the behaviour of your profiles, such as clicks, opens, bounces and errors. In other marketing software, people often keep their mailing lists separate, but this would make our behaviour tracking ineffective. We therefore advise you to always update your existing databases, instead of periodically creating new ones.
Inside the Copernica database management you find terms like collection and subprofile. These terms are related to our multidimensional database model, which allows you to keep multiple records about profiles in your database. For example, when keeping track of a profile's purchase history, you can create a collection called orders. The customer is in this case the profile and the product this profile ordered the subprofile. You could apply the same principle on for example employees of a company.
Things to consider
The most important thing to consider in your database is the structure. You want your database to be clear and effective. It's also possible to set up rules and restrictions to prevent invalid data from entering your system or sending out unintended mailings.
There is a lot to know about databases, which is why we have documented everything you need to know thoroughly. The following articles will help you build, maintain and export your databases.
