Design Principles

The Schevo schema definition syntax and database usage API were designed very carefully with several design principles in mind.

In no particular order, they are as follows:

  • Code readability.
  • Provide deep introspection allowing rich auto-generated user interfaces.
  • Convenient use in a Python shell: help the user while staying out of their way.
  • Name and call-signature symmetry and consistency.
  • Straightforward and consistent extension of default behavior.
  • Encourage composition of smaller pieces into larger ones.
  • Prefer declarative over imperative.
  • Take full advantage of the core Python language.
  • Data consistency assurance.
  • Namespace collision avoidance.
  • Reduction of boilerplate code.
  • Minimal of reserved words.
  • Separate layers of functionality, but keep related layers nearby in the source code.
