Add more database primitives

**Is your feature request related to a problem? Please describe.**
Database types like Date and Timestamp are inserted as strings/ints. These strings/ints are fixed no matter what database is targeted. Some databases add integrations for these types. This could lead to incompatibility when other systems try to use the database too.

**Describe the solution you'd like**
Add more primitive support. Support common values like described [here](https://docs.mongodb.com/manual/reference/bson-types/). Than leave the saving to the database implementation.
