Using EF Core I'm struggling how to model data. I'm also new to EF so bear with me.

We are storing personnel data thats changed, so some fields will be strings like name, some will be objects (Value Objects) like addresses, boolean flag values and dates. We need to try to keep the correct data type for type saftey, only a very limited subset of the data will be stored.

As you can see we have every kind of data to persist.

I'm struggling how to even model this using a data first approach let alone EF.

I'm kinda leaning towards saving everything as strings and use code inthe domain layer to check / maintain type safety, but value objects like address still present a problem, do I have a single row for all proprties or a separate row with a key and 1 property per row?

Not all data will be relavent or persisted per person, for example 1 person might update their name, another their address and another their marketing preferences, these need to be stored temporarily until approved when the master record will be updated.

Does anyone get what I'm after and any pointers on how to get going.
