A short guide to Anorm
/*
Overview
--------
To run a query using anorm you need to do three things:
1. Connect to the database (with or without a transaction)
2. Create an instance of `anorm.SqlQuery` using the `SQL` string interpolator
3. Call one of the methods on `SqlQuery` to actually run the query

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?
