ORM Safari! Part I

We are taking a surprise trip to the Savannah for a safari to see all sorts of exotic animals. During our time there we want to keep track of all the animals we have seen. For this, we need to create a database, as well as a small console application to help record what we see.

Objectives

• Use an ORM to query against a database

Requirements

Additional Reading

NOTE: The Additional Resources section below is very helpful. Consider reading this after reading Explorer mode. Then make a plan for the assignment for digging in and writing code.

Setup

dotnet new sdg-console-database -o SafariConsole

Explorer Mode

• Create a database called SafariVacation
  • This will have 1 table called SeenAnimals that has the following columns
    • Id (int)
    • Species (string)
    • CountOfTimesSeen (int)
    • LocationOfLastSeen (string)
  • NOTE: This should be made all in the code (C#), and not created in the pgcli.
• Create a small console application, and create the following queries using your languages ORM.
  • Display all animals the user has seen
  • Update the CountOfTimesSeen and LocationOfLastSeen for an animal
  • Display all animals seen in the Jungle
  • Remove all animals that I have seen in the Desert.
  • Add all the CountOfTimesSeen and get a total number of animals seen
  • Get the CountOfTimesSeen of lions, tigers and bears

Adventure Mode

• Add a new column called LastSeenTime, with a type of DateTime. This will require you to add and run a new migration.

Epic Mode

• Continue to make progress on your capstone project. This should be tasks like Database Schema, HTML, CSS
