1. Table: Items

   • This table will store information about base items like powerups.

   CREATE TABLE items (
       item_id serial PRIMARY KEY,
       name VARCHAR(255) NOT NULL
   );
   

2. Table: Synonyms

   • This table will store synonyms for each item, referencing the items table.

   CREATE TABLE synonyms (
       synonym_id serial PRIMARY KEY,
       item_id INT REFERENCES items(item_id),
       synonym VARCHAR(255) NOT NULL
   );
   

3. Table: Genres

   • This table will store different genres, like "fantasy" or "modern day."

   CREATE TABLE genres (
       genre_id serial PRIMARY KEY,
       name VARCHAR(255) NOT NULL
   );
   

4. Table: Items_Genres

   • This table will establish a many-to-many relationship between items and genres, as an item can belong to multiple genres.

   CREATE TABLE items_genres (
       item_id INT REFERENCES items(item_id),
       genre_id INT REFERENCES genres(genre_id),
       PRIMARY KEY (item_id, genre_id)
   );
   

With this schema, you can:

• Add base items like powerups to the items table.
• Associate synonyms for each base item in the synonyms table, referencing the corresponding item.
• Categorize base items into different genres in the genres table.
• Establish relationships between base items and genres in the items_genres table.

Here's an example of how you might use this schema:

-- Insert a base item
INSERT INTO items (name) VALUES ('Health Potion');
-- Insert synonyms for the base item
INSERT INTO synonyms (item_id, synonym) VALUES (1, 'Health Potion');
INSERT INTO synonyms (item_id, synonym) VALUES (1, 'Stimpack');
-- Insert genres
INSERT INTO genres (name) VALUES ('Fantasy');
INSERT INTO genres (name) VALUES ('Modern Day');
-- Associate the base item with genres
INSERT INTO items_genres (item_id, genre_id) VALUES (1, 1); -- Health Potion belongs to Fantasy
INSERT INTO items_genres (item_id, genre_id) VALUES (1, 2); -- Health Potion also belongs to Modern Day
-- Select the Fantasy name of an the heavy armor base item that you are looking for.
SELECT genres.name
FROM genres
JOIN items_genres ON genres.genre_id = items_genres.genre_id
JOIN base_items ON items_genres.base_item_id = base_items.item_id
WHERE base_items.name = 'heavy armor'
  AND genres.name = 'Fantasy';
