Domain Modeling F# sample

A domain modeling exercise in F#

Cafe:

Entities and/or values involved are the cafe, the available foods, the table, and the orderitems. There are plain member methods in those entities/values that return new entities/values. Events are "wrappers" for root methods. Commands produce events (or an error).

In a real application, we just need to deal with how to store (and reapply) events, and how to store and read snapshots.

How to run tests:

in cafemodelingtest directory using terminal/command line console:

    dotnet run

or

    dotnet test

Hotel:

The hotel example is an evolution to the cafe example. There are rooms and bookings. Events, commands, and domain objects are seralizable via json. Events and snapshots are stored in a Postgres database that needs proper setup. Note: proper postgres setup is needed to compile. See the dmhotel.slq script and Db.fs source file to figure out proper dbname and user and user credentials needed.

How to run tests:

in hotelmodelingtest directory using terminal/command line console:

    dotnet run

or

    dotnet test

Todo:

1. move some events and command related methods that are similar, in a common library/project
2. a web interface
3. evolve the cafe subproject in the same way as hotel subproject did (serialize and store events)
