Review the pdf documents attached. Use the theory (specifically what is covered between slides 4-24 to 4-63) to convert the provided ER Schema into a temporal ER Schema. Every decision needs to be DOCUMENTED: Phase I Start with Temporal Normalization (start with identifying time variant vs. time invariant entities, attributes, relationships and why then normalize). What Time Domains you are going to be using and their definitions (event time, transaction time, etc.), what is the your Chronon for each temporal element and why, State or Event modeling for each temporal element and why, instant or interval timestampings where and why. Phase II Grouping of time-variant attributes (temporal denormalization). Examine the Lifespan of your objects and determine if you are having any Parallel Histories. The project file attached has the ER diagram and was created in SQK Workbench
