SQLite: generate database schema via EGX/EGL
As a continuation of #29 (closed), it would be good to automatically generate the schema of the SQLite backend via EGX/EGL, and decouple most of the core code of the backend from it (e.g. by introducing an ISchema
interface + a NonTimeAwareSchema
implementation). We could then produce the time-aware version of the schema through a model-to-model transformation.
